Today was in dr. Head chose headphones. I listened to many and the choice fell on these Bowers & Wilkins Px7 S2. Everything was super sound, quality, power reserve, but there was one nuance that haunted me, at maximum volume when listening to the track while the music is playing, everything is gorgeous, and when the voice appeared, the music was muffled slightly, and a swing appeared on every word in the lyrics itself the sound is muted. I ended up getting the adidas RPT-01, I don't know what they did with the sound, but these headphones sound great, just listen to them before you buy and you will look askance at the Bowers & Wilkins Px7 S2.
