The AKG N700NC M2 Wireless are the next generation of the AKG N700NC Wireless. They have an adaptive active noise cancelling (ANC) system that automatically adjusts its level to better match your environment. They also have a longer continuous battery life of over 20 hours, support multi-device pairing, and come with a 1/8" TRRS cable with an in-line mic. Their slightly bass-heavy sound profile can be adjusted to your liking using their companion app's parametric EQ too. On the downside, some users have reported that their unit's hinges broke with continuous use.

Our Verdict

8.0 Neutral Sound

The AKG N700NC M2 are great for neutral sound. They have a slightly bass-heavy sound profile that delivers a touch of extra thump, rumble, and boom to mixes. That said, if you're looking for a more neutral sound profile, you can adjust their sound to your liking using their companion app's parametric EQ and save your favorite presets. Unfortunately, their passive soundstage seems closed-off and unnatural.

Pros
  • Comfortable and well-built.
  • Parametric EQ available.
Cons
  • Disappointing passive soundstage.
7.8 Commute/Travel

The AKG N700NC M2 are very good for commute and travel. These over-ears have a comfortable, well-built design and have an ANC system that can adapt to your environment to block out background noise more efficiently. Thanks to this system, they can block out the low rumble of bus and plane engines. Their over 20-hour battery life should also last through long commutes or trips without too much of a problem.

Pros
  • Adaptive ANC can block out background noise well.
  • Comfortable and well-built.
  • Over 20 hours of continuous playback time.
Cons
  • Bulky design.
7.4 Sports/Fitness

The AKG N700NC M2 are decent for sports and fitness, although they're not designed for this use. They have a comfortable as well as stable fit for light runs in the park, and their wireless design keeps the risk of something snagging your headphones off your head low. However, they can fall off your head with more intense head movements. They also lack an IP rating for water resistance.

Pros
  • Comfortable and well-built.
  • Over 20 hours of continuous playback time.
Cons
  • Bulky design.
7.7 Office

The AKG N700NC M2 are good for office use. They have a comfortable fit, long-lasting continuous battery life, and can be paired with up to two devices at a time, which is nice if you want to stay connected to your PC and smartphone at the same time. They also have active noise cancelling and can cut down a great amount of noise, like ambient chatter, so that you can focus on your work.

Pros
  • Adaptive ANC can block out background noise well.
  • Comfortable and well-built.
  • Over 20 hours of continuous playback time.
Cons
  • Bulky design.
6.1 Wireless Gaming

The AKG N700NCM2 aren't suitable for wireless gaming. You can use them with Bluetooth-compatible PCs, but their latency is likely too high to be suitable for gaming. They also aren't compatible with Xbox or PlayStation consoles.

7.7 Wired Gaming

The AKG N700NC M2 are good for wired gaming. They can connect to any console with an AUX port, thanks to their included 1/8" TRRS cable, which also has an in-line mic so that you can chat with teammates. Their slightly bass-heavy sound profile helps emphasize sound effects while you game, but it shouldn't overwhelm dialogue or instrumentals. They also have a comfortable fit.

Pros
  • Comfortable and well-built.
  • Over 20 hours of continuous playback time.
Cons
  • Sub-par noise handling.
7.0 Phone Calls

The AKG N700NC M2 are satisfactory for phone calls. Using their integrated microphone, recorded speech sounds clear and natural. However, the mic struggles to separate your voice from moderate ambient noise, so you may have some trouble being understood if you're taking a call from a noisy environment like a busy street. On the upside, they come with a 1/8" TRRS cable that includes an in-line mic. This mic offers a slightly better noise handling performance with background noise like that in a subway station.

Pros
  • Adaptive ANC can block out background noise well.
  • Comfortable and well-built.
Cons
  • Sub-par noise handling.
  • 8.0 Neutral Sound
  • 7.8 Commute/Travel
  • 7.4 Sports/Fitness

The AKG N700NCM2 have good controls. There are physical buttons on each ear cup, which are clicky. There's a chime to let you know when you've reached max volume and when you've paired the headphones to your device. There aren't any voice prompts, though, and the beeps sound similar for all commands.

On the left earcup:

  • '+' button:
    • Single press: Raises the volume.
    • Three-second press: Skips the track forward.
  • '-' button:
    • Single press: Lowers the volume.
    • Three-second press: Skips the track backward.
  • Center button:
    • Single press: Plays and pauses audio. Also answers and ends calls.
    • Press and hold: Declines a call.

On the right earcup:

  • Action (AmbientAware) button:
    • Single press: Turns 'AmbientAware' on and off. This setting keeps your audio at the same volume while also letting you hear your surroundings. You can remap this command to trigger 'TalkThru' via the companion app instead. This is advertised to boost the frequency range of human voices and reduce your own audio's volume so that you can hear conversations more clearly. When you're in a call, this button also mutes and unmutes your mic.
    • Double press: Activates voice assistant.
  • Power button:
    • Single press: Turns the headphones on and off.
    • Slide downwards: Enters Bluetooth pairing mode.

Design
Build Quality

The build quality is good. They're mostly made of plastic, with faux leather padding and a metal plate to help reinforce the headband. As a result, they should be able to survive an accidental drop or two without taking too much damage. However, some users have reported the hinges of their units breaking over continuous use.

7.5
Design
Stability

The AKG N700NCM2 have a slightly more stable fit than the AKG N700NC Wireless due to their higher clamping force. However, they're not designed for use during workouts or sport and can fall off your head with more intense movement. They shouldn't move around if you're listening to audio at your desk or on the couch, though.

The AKG N700NC M2 have a slightly bass-heavy sound profile that delivers a touch of extra thump, rumble, and boom. They don't sound very bloated, and vocals and lead instruments are clear, present, and detailed in your mixes. If you prefer a different sound, their companion app offers a parametric EQ that you can use to adjust their sound to your liking.

The frequency response consistency is decent. You may notice a drop of bass if you have thick hair or glasses. However, it's somewhat minor. The headphones are more sensitive to fit and positioning, though, which can affect treble delivery. You may need to adjust them on your head each time you use them to get a more consistent sound.

The AKG N700NC M2 have an adaptive ANC system that automatically adjusts its level to better suit the noise around you. As a result, we can't properly test this feature as its performance can vary depending on the environment. That said, when using our test signal, they can block out an okay amount of bass-range sounds like the low rumble of bus and plane engines. They can also cut down a significant amount of ambient chatter as well as the high-pitched hum of an AC unit.

Note: These headphones have an ANC system that can't be turned off. To test passive noise isolation, we turned the headphones off.

The mic's noise handling performance is sub-par. It struggles to separate your voice from moderate ambient noise around you, which could be frustrating if you're taking a call from a busy street.

The in-line mic offers a similar performance with pink noise. The background noise is noticeable and annoying, but the voice is still present and clear. You can hear a recording of the in-line mic's pink noise handling here. When it comes to subway noise, the in-line mic offers better noise handling performance than the integrated mic. While your voice gets lost in very loud noise, it can still keep your voice above moderate ambient noise. You can hear the subway noise handling recording here.
