Sound

Sony WH-H900N produces a well-balanced sound that has a good amount of bass that thumps and rumbles without overpowering the instruments and vocals in the mid-range. The ANC does not have a noticeable effect on the audio quality, which is good, as some headphones with ANC lose range within the low-end of the spectrum with the feature switched on.

Sennheiser HD 4.50 BTNC provides a very balanced sound with a decent level of bass and very clear vocals and instruments. The sound signature is amazing and works with different music genres.
