B&W (Bowers & Wilkins) PX-7 Headphones

These are amazing, well built audiophile headphones in immaculate condition. I've used them both wireless via bluetooth and wired and they always sound terrific. Their heritage as studio monitors at Abbey Road shines through. They ship in the original box with the accessories. I'm not sure why they look blue in the first two photos - they're gray.

The PX7 Wireless headphones offer Bluetooth for playing music wirelessly and include adaptive noise-canceling circuitry. Yet they still manage to preserve B&W's heralded spacious, detailed sound. Their completely redesigned 43mm drivers were developed and created by the sound engineers responsible for B&W's flagship 800 D3 loudspeakers.  

Music plays wirelessly from your phone via Bluetooth 5.0 — the strongest, most reliable Bluetooth yet. You can pair to two devices at the same time — a home office game-changer! For example, if you're connected to both your laptop and phone, it's much easier to toggle back and forth from music to calls to Zoom meetings and more.

The PX5s and PX7s are also the first group of headphones to feature aptX® Adaptive technology. This versatile wireless audio codec automatically detects if you're in an area with competing Bluetooth signals, and adjusts accordingly. In those crowded areas, it will optimize reliability over sound quality. 

These headphones boast a 30 hour battery life with noise cancellation. B&W's specially designed noise-canceling circuitry is super-flexible. A dedicated button on the side lets you scroll through different levels of noise canceling. And for what it's worth, this is the first noise cancelation I've heard that sounds natural and unobtrusive - you don't realize it's there.

When you hold the side button for two seconds, "ambient pass-through" mode is activated. This uses the headphones' built-in mics to allow in external sounds. That comes in handy if you need to be able to hear what's going on around you without taking the phones off. If you do, though, the headphones will automatically pause your music when you remove them or lift an earcup. Then they'll resume playing when you put them back on.
