Well it figures that Kef would finally come out with headphones JUST after I spend a fortune on B&W. I tested the Bose and the Beats, the Sennheisers, the Harman Kardon, and even the Sol Republics. I could not do better than the P5s by Bowers and Wilkins.
The P5s were just an amazing set of headphones. I have never heard such crisp music w/o any shrillness even at loud volumes. The bass was stable but not concussive, I could hear all that was recorded w/o requiring the speaker to add it's own sound like some hip-hop is recorded to do, shaking the car. I only heard the track in it's purist form. Every selection I played on them was flawless unlike EVERY other headphone I tried, always some problem stood out.
Well, I didn't test the Parrots, but I am not a battery powered headphones guy, and I really don't want noise canceling. Why suffer with distortion ADDED by your headphones. So I spent the money and got the P5s for regular use and the P3s because they were so close to the P5s, slightly less bass presence, but quite a few less dollars. Then if the wife wants to listen to something at the same time I got no complaints.
Then right after they arrived the P7s came out. I was so angry until I got a chance to listen to them. They were even less bass than the P3s, although not as clamped on your ears either. Hopefully overtime that will not be so harsh.
Now it has been half a year and the KEFs are out. I love KEF. My 104A/B stereo speakers that I have had since I was 17 (after my sister took her JBLs to college) are still my main speakers. When surround became a thing I got the KHT 3000 series with subwoofer, rocks my world when watching BluRay. The review you did was epic and sold me on buying the KEFs, I just wish you had ever done a review of the P5s when they were new, I think they would have impressed. Certainly nothing else on the marketplace of stores I can walk into and buy/return.
