Sennheiser Momentum 2 is a multipurpose and very comfortable device for its large over ear closed cups, light weight, comfort, and wired and wireless connection options.
For the over average Sennheiser Momentum 2 specs it should reproduce a high fidelity sound. That is supported by a wide field of frequency response - 16Hz-22KHz. 120 dB sensitivity works great for loud volumes. 28 Ohm of impedance is great for connection to almost all audio devices.
The incredible battery life of 25 hours plus a fast charge time that will take just 2 hours is great for portability and use in travels. There is also a battery free listening mode and battery level indicator. The NFC is supported.
The bass is deep and bright, as well as all other ranges that are not overshadowed by the lows. Everything is reproduced with a brilliant fidelity still flat enough for neutral listening. They are not sharp and rather warm with not too crisp highs that might scratch very sensitive ears. They will suit most music genres. Of course we should not expect a wide soundstage for its closed cups design, still the sound quality is above average.
The ANC is adjustable and it does a pretty good job. It does not cancel loud noises and still reduces them quite well and comfortably for hearing.
The wired connection is supported with a detachable cable 140 cm/4.6 ft long. The Bluetooth version is 4.0.
Sennheiser Momentum 2 is incredibly light. It weighs just 140 g/4.9 oz. The adjustable headband adds comfort to the fit and it may be worn for long hours. They are also quite portable with its folding cups to take less space in your bag. The built-in microphone for calls and gaming, control buttons, and voice add functionality to this device.
