Our Verdict
Bose QuietComfort Ultra Headphones Wireless
Bowers & Wilkins Px7 S3
The Bose QuietComfort Ultra Headphones Wireless and Bowers & Wilkins Px7 S3 are high-end headphones. The Bose feel more comfortable and lightweight for most people with much better noise isolation performance. Their sound profile is more excited in the treble by default. The Bowers & Wilkins are comfortable too, even with glasses, but their noise isolation isn't as impressive. Still, their mic is a bit better, and depending on your tastes, the bass-heavy tuning may appeal to you.
