But now to the headphone itself, which is made of quality materials, including stainless steel and Alcantara. The latter is known for its durability sufficiently. Momentum is very easy and convenient adjustable. The thick, soft earpieces fit perfectly and tightly. Even after prolonged use, the skin does not sweat under the covers. The 1.4 meter long cable with remote control and built-in microphone is detachable.
I am using the Sennheiser MOMENTUM On-Ear G (M2) mainly on my Sony Xperia smartphone for music and sound reproductions. The sound is better many times over the use without a headset. It's amazing how tremendously improves the sound quality. Outside noise are imperceptible.
But to call the headphones are perfect. My interlocutor can understand me better when I use the headset, as it comes with the cable microphone my voice better catches than the micro of my Xperias. Our LG 7 and our Sony VAIO laptop headphones are also compatible.
The three buttons on the remote (high, low and "play") are easy to operate. About "play" you can start playing songs or select the next track. Too bad that this key can not be used to answer and end phone calls.
Basically, the Sennheiser MOMENTUM On-Ear G (M2) from the usual high-end audio manufacturers experience and deserves 5 stars.
