I hear my music from mobile phone via Spotify via Bluetooth. The good thing about the headphones is that you can directly in front of the title, turn back and pause. The volume can be adjusted without looking directly at the headphones adjust easily and quickly. I thought that was great. The sound is really good for me in this price range. Everything sounds clear and the bass comes over very well. Noise Canceling I do not overwhelming. It works, but is not outstanding. Could even the Bose headphones test are indeed known but also have a different price range. However, these are worlds here. Not only the price, special just how it works. The Bose makes saugut and here at the Sony, it is rather a small technical support for the suppression of ambient noise. I recommend the headset to all cases and did not think I get these features for the money. The processing is really great for this price. Why I sent him back is the reason that the temple was too wide for my head. The headphones sit, but were not strong enough as I'm used to it by others. If I had a hat on, it was ideal. Otherwise, it is not suitable for my head as he slid in small jerky movements of the head. Why is this so far no one complained I do not know. But perhaps because of the shape of my head :-)
