I did try to give them a chance though and proceeded to loosen the drivers up (burn) by playing music nonstop through them for a good 50 to 60 hours. The mids seem delicately pushed , showing signs of slightly bloated lower-mids; upper-mids have oddly good detail, vocals sound superb but sometimes too bassy.

so I began burning-in using the sound profile using pink noise once again (they had about 45 hours of burn-in already on them). He doesn't measure headphones, just collects measurements from other sites and uses that data to create EQ profiles. If you want to get the most out of iPhone or iPod, headphones don't come any better than the Bowers and Wilkins P5 Wireless headphones.Finally, the skull ripping “Come On” from Stanley Clarke’s The Toys Of Men was served up with full impact by the P5s.

I heard instruments in this song that I’d never heard before and, according to iTunes, I’ve listened to it well over 300 times. Listening to the latest from Moe, Smash Hits, Volume One, the vocals were natural and lacking any kind of artificial push. B and W P5 Wireless brings you a remarkably natural sound and a luxuriously comfortable fit that makes longer listening sessions a pleasure. We are clearly bass deficient although how much, we don't know due to fitment issues (and listener preference).

The headphone does struggle to render sub-bass with the same conviction as my Fostex TH900 or Shure SE846 but an allowance has to be made for the physical limitations of the P5S2.
