Features

Talking about impedance, I've realized that Sennheiser Momentum 2 has 28 Ohm and this is one and a half times more than HD 4.50 BTNC does — 18 Ohm. The frequency response of the first headphones is 16 Hz - 22 kHz, which is a bit wider than in the case with Sennheiser HD 4.50 BTNC — 18 Hz - 22 kHz. The appliance Momentum 2 has 120 dB of sensitivity and HD 4.50 BTNC has 113 dB.

These headphones from Sennheiser support aptX. After two hours of charge Sennheiser Momentum 2 can work 25 hours, while the battery life of the other one is 19 hours. Well, you can listen to music with Sennheiser HD 4.50 BTNC for 25 hours if you do not use a noise-canceling option.

Sound

Sennheiser Momentum 2 has lovely transparency. These headphones have a surprisingly rich spectrum. With this device you can hear the subtle raspy timbre of a voice and every expressive nuance of a bass tone.

The sound of Sennheiser HD 4.50 BTNC is incredibly crisp and vibrant. The bass here is not overbearing. NoiseGuard cancels constant ambient noises like fans, airplanes, street traffic, etc.

Comfort and design

The model of headphones Sennheiser Momentum 2 weighs only 140 g and it is really light if to compare with the weight 238 g which HD 4.50 BTNC has. Buying one of these devices you get a special case, therefore taking into account the fact that both Sennheiser headphones are foldable, they are easy to carry. An adjustable headband is one more detail that makes them convenient.

When I used Sennheiser HD 4.50 BTNC, there was some lag between button press and play/pause operation. The lack of distinct click made me wondering whether I have really pressed the button or I should push harder.
