Bowers & Wilkins P7 Wireless is worth the price. Its sound quality is so good that once you put it in your ear, you won't take it off. Some of the reviewers claimed that while listening to the song “Hello” by Adele, one could hear instruments they are unable to do with other wireless headphones. B&W P7 wireless are primarily made for sound, but they don't have noise cancellation feature. On the other hand, MDR-1000X combines the noise cancellation of the Bose QC35s and the thumping sound of the P7 Wireless. Trusted Reviews said that the Ambient Sound and Quick Listen modes are very useful features that give listeners a lot of flexibility. Regarding sound quality, the review claims that it is outstanding. I think its sound quality is much better than B&W P7 wireless.
