Q & As

Sennheiser MM450-X On-Ear Noise Cancelling Bluetooth Headphones, Black 4 5 1 1
Very good noise cancelling + bluetooth headphones. It's very good headphone, sound really good. One short coming is it's short battery life compared to my old Nokia BH-905i, I just bought an extra battery for that. Here's a tip (I went to Sennheiser service centre): Some of the reviews I read complaint about it doesn't sound as loud when powered on, plugged into cable with/without noise cancelling turning on; just press the volume up on the headphone. 15 August 2014
