The Audeze MM-100 are wired open-back headphones with planar magnetic drivers. They're one of two headphones designed in collaboration with Grammy award-winning engineer/producer Manny Marroquin, intended as a mid-range alternative to the more premium Audeze MM-500. They're designed with studio applications in mind, so they sport gel-filled earpads and an adjustable ski-band-style headband that aims to make long recording sessions as comfortable as possible. Their low sensitivity and impedance also mean you can use them with a phone or laptop without a dedicated amp or sound card to drive them.

Our Verdict

7.7 Neutral Sound

The Audeze MM-100 are very good for neutral sound. Their open-back, planar magnetic design means they have a sound profile that lacks rumble and thump in the bass range but reproduces vocals and other mid-range instruments with plenty of detail and clarity. The recessed low and mid-treble dulls sibilants somewhat but can be advantageous in avoiding ear fatigue over long mixing sessions. Their soundstage performance is impressive and provides ample separation of instruments in the stereo field. While the comfortable, gel-filled earpads go a long way in offsetting the heft of their planar drivers, they can still feel heavy on the head after extended use.

Pros
  • Immersive, open-sounding soundstage performance.
  • Comfortable fit and excellent build quality.
Cons
  • Bulky and heavy design.
3.6 Commute/Travel

The Audeze MM-100 are studio headphones that aren't intended for use on the go. As a result, they're a poor choice for commuting and travel use as their bulky design means they're not very portable. Their open-back design also provides almost no isolation against external noise, and they leak enough audio for others around you to hear on the bus or train. On the upside, though, they're comfortable and well-built enough to survive long journeys.

Pros
  • Comfortable fit and excellent build quality.
Cons
  • Bulky and heavy design.
  • Poor noise isolation performance.
  • Leak a lot of audio.
5.2 Sports/Fitness

The Audeze MM-100 are disappointing for sports and fitness use as they're not intended for this purpose. Their bulky design is prone to falling off your head during more intense movements, and it's easy to get the audio cable snagged on things while you're in motion. They also lack any controls to change the track or adjust the volume on the fly.

Pros
  • Comfortable fit and excellent build quality.
Cons
  • Bulky and heavy design.
  • Leak a lot of audio.
4.3 Office

The Audeze MM-100 are studio headphones that aren't designed for use in an office setting. While they're comfortable enough to wear at your desk, they provide almost no isolation against external noise, so it's easy to get distracted by office chatter. They also leak a lot of audio, so within the average office setting, others can hear what you're listening to.

Pros
  • Comfortable fit and excellent build quality.
Cons
  • Bulky and heavy design.
  • Poor noise isolation performance.
  • Leak a lot of audio.
4.3 Wireless Gaming

The Audeze MM-100 are wired headphones; you can't use them to game wirelessly.

6.4 Wired Gaming

The Audeze MM-100 are passable for wired gaming. They're comfortable enough for extended gaming sessions and provide a low latency performance via their wired connection. Their immersive soundstage makes it easy to localize sound effects, like footsteps, in the stereo field, and their accurate high-bass response helps bring them out further. They lack an integrated mic, so you'll need to purchase a standalone mic or opt for Audeze's boom mic-equipped cable.

Pros
  • Immersive, open-sounding soundstage performance.
  • Comfortable fit and excellent build quality.
Cons
  • Bulky and heavy design.
  • Poor noise isolation performance.
1.4 Phone Calls

The Audeze MM-100 are wired studio headphones with no integrated mic, so they're not suitable for taking phone calls. However, Audeze manufactures a cable with a built-in mic that you can use with these headphones.

Differences Between Sizes And Variants

The Audeze MM-100 are available in one color: gunmetal gray with a black headband and black grilles.

Please let us know in the comments if you encounter another variant of these headphones.

Compared To Other Headphones

The Audeze MM-100 are wired, open-back headphones designed for studio use and reference listening. Like the Audeze LCD 2 Classic/LC2C, they feature planar magnetic drivers and a rock-solid build quality. They also share a similar sound profile: one that lacks low-bass but features very neutral mids and a recessed treble range. They're heavy on the head, even compared to other planar magnetic headphones like the HiFiMan Sundara 2020. That said, they're not as heavy as the closed-back Audeze Maxwell Wireless, and the manufacturer has introduced gel-filled earpads with the MM-100 that aim to offset the weight better with a comfortable seal.

If you're looking for more headphones, check out our recommendations for the best studio headphones, the best headphones for music, and the best open-back headphones.

Audeze LCD 2 Classic/LC2C

The Audeze LCD 2 Classic/LC2C and the Audeze MM-100 are open-back, planar magnetic headphones from the same manufacturer. As a result, they share a lot of similar traits, with little to differentiate between them. They're both comfortable and well-built, with both headphones employing adjustable ski-band style headbands. They also have extremely similar sound profiles, with an underemphasized bass response and a recessed treble range. The main difference between the two is the soundstage, where the LCD 2 Classic sound a touch more wide and open. The LCD 2 Classic also have a higher impedance, and you'll need an amp or soundcard to drive them.

HiFiMan Sundara 2020

The Audeze MM-100 and the HiFiMan Sundara 2020 are both open-back headphones with planar magnetic drivers. However, the two have quite different sound profiles, with the HiFiMan sounding more neutral overall. They're also slightly more comfortable, and it's easier to get consistent audio delivery between listening sessions when using them. That said, the Audeze are considerably better built and more likely to be a durable, long-term option in the studio.

Beyerdynamic DT 990 PRO

The Beyerdynamic DT 990 PRO and the Audeze MM-100 are both wired, open-back audiophile headphones with slightly different strengths. The Audeze are better built using more premium materials, and their planar magnetic drivers help them create a more spacious, immersive soundstage. While both headphones have relatively neutral sound profiles, the Beyerdynamic have a more accurate bass and treble response. That said, the Beyerdynamic's slightly overemphasized treble can be fatiguing to listen to over long periods, which is less of an issue with the Audeze due to their veiled treble response.

Sennheiser HD 6XX

The Audeze MM-100 and the Sennheiser HD 6XX are both open-back, wired headphones designed for audiophiles and music professionals. Choosing between them will depend on personal preference. The Audeze are more comfortable and better built, with a more expansive-sounding soundstage. However, the Sennheiser have a more neutral sound profile overall. Both headphones lack low-bass, which is normal for open-back designs, and both excel at reproducing mid-range sounds with clarity and accuracy. However, they differ slightly in their treble accuracy, where the Sennheiser follow our target curve more closely.

The Audeze MM-100 are sleek, modern-looking, over-ear, open-back headphones that share some cosmetic similarities with the Audeze Maxwell Wireless, like the adjustable ski-band design used for the headband. Their distinctive black grilles are embossed with the Audeze logo, accented by gunmetal gray earcups and yokes. They have a unique design whereby the detachable audio cable can be plugged into an input on either earcup, allowing for greater freedom of movement while puttering about the studio.

Despite their bulky look, they're comfortable headphones. Their planar magnetic drivers add weight to the frame, and they fit quite tightly on the head, but this is offset by the plush, thick ear cup padding that feels comfortable on the skin. Although they have a ski-band design, which helps distribute the weight more evenly around your head, the sheer weight of these headphones can still cause some discomfort on the top of your head, where the ski-band rests, during longer listening sessions. The headband is only adjustable via three sets of notches, so you can't get the best fit for your head beyond these settings.

These headphones have a bulky frame. While they don't take up as much space as the Audeze Maxwell Wireless, they're still too cumbersome to carry around on your person for on-the-go use. Fortunately, they fold flat, so you can more easily stow them in a bag or in the included carrying pouch.

These headphones come with a large carrying pouch. It's made of a good quality material that's felt-like on the outside and softer on the inside to better protect your headphones. The pouch is roomy enough to fit the headphones and cables and still have space to spare.

8.5
Design
Build Quality

The Audeze MM-100's built quality is excellent. They feel durable and are made of premium materials like magnesium, steel, aluminum, and dense plastic, with a faux leather material used across the ear cups and headband. However, the braided cable doesn't feel quite as sturdy as the headphones and lacks a sleeve, making them more susceptible to wear and tear. The holes that attach the leather headband to the body will also likely degrade over time, especially if multiple people use the headphones and you're constantly readjusting the size. Overall, though, these headphones feel like they can withstand extended use in the studio.

6.0
Design
Stability

These headphones aren't very stable. Their heavy frame makes it very easy for them to shift around on your head during movements despite the tight seal they form over your ears. Intense head movements, like headbanging along to your finished mix, will cause them to slip off your head entirely.

The Audeze MM-100 have a fairly well-balanced sound profile that's comparable to other open-back headphones equipped with planar magnetic drivers, like the HiFiMan Sundara 2020. They have a recessed low-bass, which is normal for open-back designs. The mid-range is extremely detailed and accurate, resulting in a crisp and natural reproduction of vocals. However, a noticeable dip in the low and mid-treble veils some of the high-end brilliance found in the upper harmonics of vocals and dulls the sizzle of sibilants, like open hi-hats. The underemphasis in this range can help reduce ear fatigue over longer listening sessions.

These headphones also have a low impendence and relatively high sensitivity that makes them suitable for driving a range of devices, like laptops and phones, while still pairing well with soundcards, amps, and other studio gear.

The frequency response consistency is very good. Their treble and bass delivery can vary depending on fit and positioning. If you wear glasses, you'll experience inconsistencies in the bass range as the arms of your glasses can prevent a proper seal from being created. Overall, though, if you take some time to adjust the fit, you'll achieve consistent audio delivery.

The mid accuracy is outstanding. The response throughout this range is very flat and follows our target curve extremely well, resulting in a clear and accurate reproduction of vocals and lead instruments. In songs like Marvin Gaye's What's Happening Brother, the strings and rhythm guitar sound smooth and balanced, while the lead vocal sounds forward in the mix, thanks to the slight bump between the mid-mid and high-mid.

The treble accuracy is sub-par. The range as a whole is quite underemphasized, and there's a large dip between the low and mid-treble that dulls the upper harmonics of vocals and reduces the brilliance of sibilants, like cymbals.

7.5

They have good peaks and dips performance, meaning they control their sound profile well. There's a small bump in the high-bass that adds warmth to the mix and a slight dip in low-bass. There are two peaks in the high-mid and low-treble that add presence to vocals and lead instruments, followed by a significant dip between the low and mid-treble that dulls lower-frequency sibilants. A sharp peak at the top of the mid-treble range adds air and excitement to the high-end of mixes.

The imaging performance is amazing. Imaging can be a good indicator of quality control and ergonomics. However, it's worth keeping in mind that planar magnetic drivers, like those used in these headphones, are more prone to L/R mismatches due to their complex design, compared to dynamic drivers. Our unit's drivers are well-matched in group delay, resulting in tight bass and transparent highs. The L/R drivers are also generally well-matched in frequency, amplitude, and phase response. While some slight bumps are visible in the phase response in the mid-mid and low-treble, these aren't noticeable with real-life content, and instruments are correctly placed in the stereo field.

The Audeze MM-100 have an impressive soundstage performance. Their open-back design allows for a good amount of interaction with your outer ear, and their soundstage feels wide and immersive as a result. Audio sounds like it's coming from speakers placed in the room around you rather than from inside your head.
