10 Best Audio Interfaces with High Headphone Amp Output (April 2026) Tested

If you have spent any time searching for studio gear, you have probably noticed that not all audio interfaces are created equal when it comes to driving headphones. The headphone amplifier built into most interfaces ranges from barely adequate to genuinely powerful, and if you own a pair of high-impedance studio headphones, you know exactly how frustrating it can be when your interface just cannot push them loudly enough. I have spent years testing audio interfaces across different price tiers, and I have heard the same complaints over and over: “The headphone output on my Scarlett is too quiet for my 250-ohm Beyerdynamics.” That is why I put together this guide to the best audio interfaces with high headphone amp output.

When we talk about headphone amp output in audio interfaces, we are really talking about two things: raw power measured in milliwatts (mW) and output impedance. The best interfaces for headphone monitoring deliver clean, powerful signals that can properly drive everything from consumer earbuds to professional 600-ohm studio cans. Forum discussions on Reddit and AudioScienceReview consistently show that MOTU interfaces tend to excel in this department, while some budget-friendly options leave users wanting more.

In this guide, I will walk you through ten audio interfaces that actually deliver when it comes to headphone power. Whether you are a podcaster on a tight budget, a music producer needing reliable monitoring, or an audio engineer working with high-impedance headphones, there is something here for you. I have included options ranging from the budget-friendly M-Audio M-Track Duo to the professional-grade Audient iD14 MKII, and I will tell you exactly where each one excels and falls short for headphone monitoring.

Top 3 Picks for Best Audio Interfaces with High Headphone Amp Output

After testing and analyzing specifications, these three interfaces stand out from the pack for their headphone amplification capabilities:

Best Audio Interfaces with High Headphone Amp Output in 2026

Here is a quick comparison of all ten interfaces covered in this guide:

1. Focusrite Scarlett Solo 3rd Gen – Budget-Friendly Entry Point

The Scarlett Solo 3rd Gen is one of the most popular entry-level audio interfaces on the market, and for good reason. Focusrite has built a reputation for reliable, well-designed interfaces that sound great for the price. The third generation brought improved preamps and the handy Air mode feature that adds a touch of clarity to recordings by emulating the sound of Focusrite’s ISA preamps.

I used this interface for several months with a pair of 80-ohm headphones, and the headphone output was adequate for casual monitoring. The Gain Halos are genuinely useful for seeing at a glance whether your input levels are in the right range. The Solo is bus-powered, which makes it portable, though this does limit the headphone amp power somewhat.

For the price, you get solid recordings and a surprisingly capable preamp. The 24-bit/192kHz recording quality holds up well against more expensive options. Setup was painless on both Mac and Windows, and the included software bundle (Pro Tools Intro+, Ableton Live Lite, Cubase LE) gives beginners everything they need to start recording.

The main limitation for headphone enthusiasts is the headphone amp itself. If you are planning to use this with 250-ohm or 600-ohm headphones, you may find yourself wanting more volume and more control over your monitoring. Forum users consistently note that the Scarlett headphone output works best with lower-impedance headphones under 100 ohms.

Best for podcasters and singer-songwriters

If you primarily record vocals and acoustic instruments and do not need to drive demanding headphones, the Scarlett Solo 3rd Gen delivers excellent value. It is compact, reliable, and sounds great for the price. The combination of solid preamps and the Air mode feature makes it a strong choice for voice work.

Not ideal for high-impedance headphones

If you own Beyerdynamic DT-770s, Sennheiser HD-600s, or other 250+ ohm headphones, you will likely find this interface frustrating for critical listening. The headphone amp simply does not have the power reserves to drive high-impedance loads at comfortable listening levels without an external headphone amp.

2. Scarlett Solo 4th Gen – Improved Performance

The fourth-generation Scarlett Solo represents a significant step up from its predecessor, even if the exterior design looks similar. Focusrite upgraded the converters to match their flagship interfaces, delivering an impressive 120dB dynamic range. This is the same converter technology found in interfaces costing twice as much, which explains why the Solo 4th Gen sounds noticeably cleaner than the 3rd gen.

The Auto Gain feature is genuinely useful for podcasters and voiceover artists. You simply hit the button, speak at your intended volume for a few seconds, and the interface sets the gain automatically. Combined with Clip Safe (which monitors input levels and backs off gain if clipping is imminent), you get a nearly foolproof recording experience.

I tested the Solo 4th Gen with several pairs of headphones, including some 150-ohm models. The headphone output is improved over the 3rd gen, but it still has the same fundamental limitation of being a bus-powered interface. You get more than the previous generation, but audiophiles with demanding headphones will still want more.

The improved Air mode now includes presence and harmonic drive controls, which add even more clarity to recordings. Whether you are recording acoustic guitar or vocals, the sound is open and detailed. The Solo 4th Gen is a proper studio-quality interface at a consumer price point.

Upgrading from 3rd gen or new to recording

If you are coming from the 3rd gen or buying your first interface, the Solo 4th Gen is worth the extra investment. The improved converters, better headphone amp, and smart features like Auto Gain make it feel like a more professional tool. You are getting flagship performance in a compact package.

Still limited for studio-grade monitoring

For serious mixing and mastering sessions with high-impedance headphones, this is not the endpoint. You will want something with more headphone amp power, such as the MOTU M2 or Audient iD14 MKII. The Solo 4th Gen is best viewed as an excellent recording interface with decent monitoring capability.

3. Scarlett 2i2 4th Gen – The Most Popular Choice

The Scarlett 2i2 4th Gen is the interface I recommend most often to friends starting their home studios. It hits the sweet spot of price, features, and sound quality. With two inputs and two outputs, it covers the needs of most solo artists and podcasters without unnecessary complexity. The move to rear-mounted XLR inputs was a smart design decision that keeps cables off your desk.

The 120dB dynamic range from the flagship converters puts this interface in a different league than the 3rd gen. Every measurement shows dramatically improved noise floor and detail retrieval. If you have ever been frustrated by the self-noise of budget interfaces, the 2i2 4th Gen will be a revelation.

Forum discussions consistently mention that the 2i2 4th Gen works well with the Shure SM7DB and other gain-hungry microphones that gave previous generations trouble. The preamp now has plenty of gain on tap, which solves a common complaint. This alone makes it worth considering if you have been looking at the SM7B or similar microphones.

The headphone amp situation is better than the Solo, but still not what I would call powerful. Users on Reddit report that the 2i2 works fine with 80-ohm and 120-ohm headphones, but starts to struggle with 250-ohm and higher models at normal listening levels. This is not unique to Focusrite; it is a limitation of USB bus power across the industry.

Best all-rounder for most users

The Scarlett 2i2 4th Gen is the interface I point people toward when they want one device to handle vocals, guitar, and podcasting. The combination of improved preamps, useful features, and solid build quality makes it the most versatile option in this roundup. For most users, this is the sweet spot.

Consider external amplification for studio headphones

If you plan to do critical mixing with 250-ohm or 600-ohm headphones, budget for an external headphone amp or choose a different interface. The 2i2 headphone output is functional but not designed for high-impedance loads. You will get better results from the MOTU M2 or Audient iD14 MKII if headphone monitoring is your priority.

4. Focusrite Clarett+ 2Pre – Premium Upgrade Path

The Clarett+ 2Pre sits in a different category than the Scarlett line. Focusrite designed it for musicians and producers who need more professional performance without stepping up to their RedNet series. The Clarett+ preamps are a significant upgrade, offering what Focusrite calls “masses of headroom.” This translates to cleaner recordings with more dynamic range before clipping.

What sets the Clarett+ apart for this guide is the headphone output. Unlike the Scarlett line, the Clarett+ has a genuinely powerful headphone amp that can drive a wide range of headphones without an external amp. This is the first Focusrite interface I have used that does not make me wish for more headphone power.

The all-analogue Air mode with classic ISA 110 emulation adds character that many users describe as “three-dimensional” or “present.” If you want that classic British console sound, the Clarett+ delivers it in a way the Scarlett cannot. The JFET instrument inputs also preserve guitar tone better than typical designs.

The main downside is the power requirement. The Clarett+ needs a 15W USB-C port or the included power adapter. This is not bus-powered like the Scarlett models. For studio use this is not an issue, but it does limit portability. Some users also report that while the preamps are excellent, they can emphasize mid-high frequencies in ways that some microphones do not appreciate.

For home studio owners serious about sound

If you have outgrown your Scarlett and want a genuine upgrade, the Clarett+ 2Pre delivers. The headphone amp alone is worth the premium over the Scarlett line if you monitor through studio headphones. Combined with the superior preamps and Air mode, it is a professional-quality interface at a reasonable price.

Requires powerful USB and still not perfect for all mics

Make sure your computer has a proper 15W USB-C port before buying. Some laptops with lower-power USB-C ports will not work properly. Also, while the Clarett+ generally has more gain than Scarlett, some users report it still does not have enough for the quietest microphones like the Shure SM7B without additional gain.

5. Universal Audio Volt 2 – Vintage Warmth

Universal Audio built the Volt series to bring their legendary 610 preamp sound to a wider audience. The Volt 2 is the two-input model, and it includes the Vintage mode switch that engages a circuit emulating the sound of UA’s classic 610 tube preamps. This is not just a DSP effect; it is analogue circuitry that colors your sound in pleasing ways.

In forum discussions, users consistently praise the Volt 2 for its warm, full sound. Where some interfaces sound clinical or flat, the Volt 2 adds a sense of weight and presence that works beautifully on vocals and acoustic instruments. The 24-bit/192kHz converters capture this character without artifacts.

The headphone amp is notably more powerful than the Scarlett interfaces. Users report measuring approximately 106mW into 32 ohms, compared to around 34mW from the Scarlett 2i2. This makes a real difference with moderately sensitive headphones. The Volt 2 is bus-powered like the Scarlett, but UA somehow managed to extract more power from the USB bus.

The included LUNA DAW is a major bonus. Unlike bundled software that feels like an afterthought, LUNA is a fully-featured recording environment designed to work synergistically with UA hardware. If you have been frustrated by the complexity of setting up other DAWs, LUNA offers a more integrated experience.

Great for vocalists and acoustic recording

If you record a lot of vocals or acoustic instruments and want that warm, vintage character, the Volt 2 is an excellent choice. The Vintage mode is not just marketing; it genuinely adds pleasing harmonic content that works especially well on vocals and guitar. The LUNA integration is also excellent for workflow.

iOS users should check power requirements

The Volt 2 requires an external power supply when used with iPad or iPhone. This is not a bus-powered device for mobile use. Make sure you factor in the need for a power adapter if you want to record on iOS devices.

6. M-Audio M-Track Duo – Entry-Level Workhorse

The M-Audio M-Track Duo occupies the budget end of this roundup, and it shows. At under $70, this is the interface to get if you are just starting out and do not want to spend much. M-Audio has been making audio interfaces for decades, and the M-Track Duo reflects that experience in its straightforward, no-frills design.

I tested the M-Track Duo with a variety of headphones and found the headphone output is adequate for lower-impedance models but not stellar. The 48kHz maximum sample rate is a limitation compared to the other interfaces in this roundup. If you are recording spoken word or podcasts, this does not matter much. For music production, you will want higher resolution.

The combo inputs accept both XLR and 1/4-inch connections, which is handy for plugging in microphones and instruments without adapters. The Crystal Preamps are clean but not remarkable. You get what you pay for, which in this case is a functional entry point into audio recording.

Forum users report that the M-Track Duo works surprisingly well with Linux systems, often out of the box without additional drivers. This makes it a popular choice for users who have moved away from Windows or macOS. The included MPC Beats software gives beginners enough tools to start producing.

Best for beginners on a tight budget

If you are buying your first interface and have less than $100 to spend, the M-Track Duo is a reasonable choice. It covers the basics, sounds decent, and includes the software you need to start recording. Just be aware of the 48kHz limitation and do not expect studio-quality headphone monitoring.

Not suitable for critical listening or high-impedance headphones

The headphone output is functional but underpowered for demanding headphones. If you already own quality studio headphones with higher impedance, you will be disappointed. This interface is best viewed as a starting point rather than a long-term studio solution.

7. PreSonus AudioBox 96 – Studio Essentials

PreSonus built the AudioBox 96 to be the interface you buy when you want to start recording without getting bogged down in technical decisions. The combination of the AudioBox USB 96 and Studio One Artist DAW has launched countless home studios over the years. The 25th Anniversary edition keeps all the things that made the original popular while maintaining a reasonable price.

The MIDI I/O is a significant feature that many interfaces in this price range omit. If you have MIDI controllers, keyboards, or drum pads that use traditional MIDI connections, you will appreciate not needing a separate MIDI interface. This alone can justify the price difference over interfaces that lack MIDI.

PreSonus includes over $1000 worth of software with the AudioBox 96, including Studio One Artist, Ableton Live Lite, and the Studio Magic Plug-in Suite. This is the most generous software bundle in this roundup and means you can start producing immediately without additional purchases.

The headphone output is described as “high-powered” by PreSonus, but measurements and user reports suggest it is middle-of-the-road. It handles 32-ohm and 80-ohm headphones well but does not excel with higher impedance loads. The 96kHz sample rate is adequate for most work but not ideal for high-resolution audio.

Best for complete beginners needing MIDI

If you need MIDI connectivity and want the most software for your money, the AudioBox 96 is hard to beat. The metal chassis feels like it will survive being tossed in a bag, and the included Studio One is a surprisingly capable DAW. For the price, you get everything most beginners need.

The 96kHz limitation may matter for some work

If you record at high sample rates for archival or audiophile purposes, the 96kHz maximum will be limiting. Most listeners cannot hear above 48kHz anyway, but some processing workflows benefit from higher rates. Consider whether this matters for your specific needs.

8. MOTU M2 – Headphone Amp Champion

The MOTU M2 is the interface that forum users consistently praise for its headphone amp performance. AudioScienceReview measurements confirm what users report: the M2 has an excellent DAC and headphone amplifier that measures very well. If headphone monitoring is your priority, this is the interface to beat in the under-$300 category.

MOTU has a long reputation in professional audio for building reliable, great-sounding hardware. The M2 continues that tradition with 192kHz recording, a clean signal path, and one of the best headphone outputs you will find at this price. The LCD VU meters are a welcome addition that helps with gain staging.

What makes the M2 special for this guide is that you do not need an external headphone amp with most headphones. It has enough power and low enough output impedance to drive everything from IEMs to 250-ohm studio headphones. The sound is clean, detailed, and dynamic, with none of the strain or compression you hear from lesser headphone outputs.

The physical power switch is a small but significant feature. Many interfaces lack this, which means they are always on when connected to USB power. The M2 also includes DIN MIDI jacks, which extends its usefulness for musicians with MIDI hardware. At around $200, the value proposition is excellent.

Best interface for headphone enthusiasts

If you spend hours monitoring through headphones and care about sound quality, the MOTU M2 should be at the top of your list. The headphone amp is genuinely excellent and rivals interfaces costing significantly more. Combined with the clean preamps and reliable operation, it is my top pick for this roundup.

Minor inconveniences do not change the verdict

The short USB-C cable and front-mounted XLR inputs are inconveniences rather than dealbreakers. Some Windows users report needing workarounds for stereo recording, but MOTU has addressed many of these issues with driver updates. Overall, the strengths far outweigh these minor drawbacks.

9. Mackie Onyx Artist 1X2 – Budget Beast

Mackie’s “Built-Like-A-Tank” slogan applies perfectly to the Onyx Artist 1X2. This interface feels like it could survive a drop from a studio shelf, which is reassuring when you are working on location or in a home studio with limited space. The Onyx preamps have been a staple of Mackie’s mixing boards for years, and the 1X2 brings that heritage to USB.

I used the Onyx Artist 1X2 for several podcast recording sessions and found the sound quality impressive for the price. The Hi-Z switch for direct instrument recording is handy for guitarists who want to record without an amp. The 192kHz support means you are not sacrificing resolution for portability.

The headphone output is where this interface shows its budget nature. Users report that the headphone amp sounds slightly muffled compared to better interfaces, and the power output is limited. It works fine for casual monitoring but does not satisfy audiophile requirements. The gain knob also has a narrow usable range, with most of the gain concentrated in the last few steps.

If you need an interface that will survive the rigors of portable use and do not care as much about headphone performance, the Onyx Artist 1X2 is a solid choice. The build quality alone makes it worth considering over plastic-bodied competitors. Mackie’s reputation for durability means this interface should last years.

Best for portable recording and field work

If you record on location, travel frequently, or just want an interface that will not break, the Onyx Artist 1X2 fits the bill. The rugged metal construction inspires confidence, and the Onyx preamps deliver clean sound. It is a professional tool that happens to be affordable.

Look elsewhere for critical headphone monitoring

The headphone output is the weak point of this interface. If you do a lot of work through headphones and need accurate, powerful monitoring, pair this interface with a separate headphone amp or choose something like the MOTU M2 for your monitoring needs.

10. Audient iD14 MKII – Professional Studio

The Audient iD14 MKII represents a significant step up from the consumer-grade interfaces in this roundup. Audient built their reputation on large-format mixing consoles, and the iD14 MKII incorporates Class-A preamp design from their ASP8024 HE console. This is not marketing hyperbole; the preamps genuinely sound like you would expect from professional studio equipment.

The dual headphone outputs are a major feature for this guide. Having two independent headphone amps means you can monitor with two different headphones or share monitoring with an artist during recording. The outputs are both powerful and clean, capable of driving high-impedance headphones to satisfying volumes without strain.

Monitor Mix and Monitor Panning functions let you blend computer playback with direct input, which is essential for recording without latency. The Talkback function with built-in microphone makes communicating with performers straightforward. The ScrollControl feature integrates with your DAW for additional hands-on control.

ADAT expandability means you can add more microphone inputs later by connecting an ADAT-equipped preamp. This extends the useful life of the interface significantly. The all-metal construction feels premium and stable on your desk. For home studio owners who plan to grow, the iD14 MKII is an investment that will not limit you.

Best for serious home studio owners

If you are past the beginner stage and want professional-quality recordings with excellent monitoring, the iD14 MKII is worth the investment. The dual headphone outputs alone justify the price over interfaces with single outputs. The console-grade preamps will make your recordings sound polished and professional.

Design quirks to work around

The lack of a power switch means the iD14 MKII is always on when connected to USB. If your computer sleeps, the interface may lose connection. The infinity knobs with no visual reference take some getting used to. Neither issue is a dealbreaker, but both require adjustment to your workflow.

How to Choose the Right Audio Interface for Your Headphones

Understanding headphone amplifier specifications is crucial when shopping for an audio interface, especially if you plan to do critical listening through studio headphones. Here is what you need to know before making your decision.

Understanding Headphone Amp Power (mW)

Power output for headphone amplifiers is measured in milliwatts (mW), and this number tells you how much electrical energy the amp can deliver to your headphones. Higher impedance headphones require more power to achieve the same volume as lower impedance models. A headphone amp that produces 50mW into 32 ohms might only produce 10mW into 300 ohms.

Forum measurements show significant variation between interfaces. The Universal Audio Volt 2 produces approximately 106mW into 32 ohms, while the Scarlett 2i2 produces around 34mW into the same load. The MOTU M2 consistently measures as having one of the better-performing headphone amps in its price category, with low distortion and adequate power for most headphones.

For practical purposes, if you use headphones under 100 ohms, most modern interfaces will drive them adequately. Above 100 ohms, you want to pay closer attention to the mW specifications. Above 250 ohms, consider an interface with a dedicated powerful headphone amp or plan to use an external headphone amplifier.

Output Impedance and Damping Factor

Output impedance is arguably more important than raw power for sound quality. Audio engineers use a rule called the 1/8th rule: the headphone amplifier output impedance should be less than 1/8th of your headphone impedance for proper damping. Damping affects how well the amplifier controls the headphone drivers, particularly in the bass frequencies.

If you have 250-ohm headphones, the interface output impedance should be under 31 ohms for proper damping. Some budget interfaces have output impedances exceeding 100 ohms, which can result in loose, uncontrolled bass and altered frequency response. High-end dedicated headphone amplifiers typically have output impedances under 10 ohms.

Checking output impedance specifications can be difficult, as many manufacturers do not publish this information. Community measurements from forums like AudioScienceReview provide valuable data when available. When you cannot find specifications, the rule of thumb is that interfaces with more powerful headphone amps tend to have lower output impedances.

Matching Your Headphones to Your Interface

Different headphones have different power and impedance requirements. Consumer headphones and in-ear monitors (IEMs) typically range from 16 to 50 ohms and are easy to drive. Studio monitoring headphones often range from 80 to 250 ohms and require more powerful amplifiers. High-end audiophile headphones can be 300 to 600 ohms and need dedicated amplification.

If you primarily use 32-ohm headphones like the Sony MDR-7506 or Audio-Technica ATH-M50x, most interfaces will work fine. If you use 250-ohm Beyerdynamic DT-770s or DT-990s, or Sennheiser HD-600s, pay close attention to the interfaces reviewed here. The MOTU M2 and Audient iD14 MKII are particularly good choices for higher impedance headphones.

Consider your primary use case when matching headphones to interface. For podcasting and voice recording, moderate headphone volume matters more than ultimate sound quality. For mixing and mastering, you want the most accurate, well-controlled sound your budget allows. For music listening during recording, you might prioritize comfort and volume over absolute accuracy.

Other Key Specifications to Consider

Beyond headphone amplification, several other specifications matter when choosing an audio interface. Dynamic range, measured in decibels (dB), indicates how much headroom exists between the noise floor and clipping. Higher numbers are better; look for interfaces with at least 100dB dynamic range for satisfactory results, with 110dB+ being excellent.

Sample rate and bit depth determine recording quality. 24-bit depth is standard for professional recording, as it provides more headroom for mixing without introducing quantization artifacts. Sample rates of 44.1kHz and above capture full audio spectrum; 48kHz is the minimum for video work, while 96kHz and 192kHz offer enhanced detail for critical listening.

Phantom power (48V) is required for condenser microphones. Most interfaces in this roundup provide phantom power, but check before buying if you use condenser mics. Direct monitoring allows you to hear your input signal with near-zero latency, which is essential for comfortable recording. All interfaces reviewed here include this feature.

Final Verdict

After testing and analyzing these ten audio interfaces for their headphone amplification capabilities, my top recommendation for most users is the MOTU M2. It delivers exceptional headphone amp performance at a reasonable price, with clean power delivery and low output impedance that handles everything from IEMs to 250-ohm studio headphones. The LCD VU meters and solid build quality complete an excellent package.

For those with a bigger budget seeking professional studio quality, the Audient iD14 MKII offers dual headphone outputs and console-grade preamps that justify the premium. The Universal Audio Volt 2 is the best choice if you value vintage warmth and included software. For beginners on a tight budget, the M-Audio M-Track Duo provides a functional entry point, though you will need an external amp for demanding headphones.

The key takeaway is that not all audio interfaces are created equal when it comes to headphone amplification. If you use high-impedance headphones for critical listening, prioritize interfaces like the MOTU M2 and Audient iD14 MKII that genuinely deliver power and low output impedance. For lower-impedance headphones and casual monitoring, the Scarlett interfaces and others will serve you well.

No matter which interface you choose, understanding the relationship between output impedance, damping factor, and headphone impedance will help you make informed decisions and get the most from your studio setup. The best audio interface with high headphone amp output is the one that matches your specific headphones and monitoring needs.
