Things We Liked

Bowers & Wilkins PX Wireless Headphones

Pound for pound, Bowers & Wilkins make some of the best headphones you'll ever experience. One of my workhorse companions is the P5, which provide an excellent soundstage, as well as being one of the most comfortable pair of headphones I've ever tested. And to be honest, this praise extends to their entire line.

With the PX, the soundstage feels very familiar - incredibly detailed, yet full of warmth - however, it's the noise cancellation that makes this the company's most ambitious project to date. Using the B&W Headphone app, you can cycle through 3 different noise cancellation modes: Office, City and Flight - each one providing varying degrees of immersion and situational awareness. You can also boost the volume of sounds around you with the Voice Pass-through option.

Gone are the days whereby noise cancellation was an all or nothing proposition, with the PX you get a ridiculous amount of control - leaving you fully immersed when you need it, or open to the world around you when you need to be aware of your surroundings.

The next cool thing to mention about the PX is its built-in sensors, which have been designed to work with the user. Say you're listening to music in your office and someone comes over to speak to you - typically you'd have to reach to the source to hit pause or fumble for a button on the headphones - but with the PX all you need to do is lift up one of the ear cups, or hang them around your neck, and the music will pause. Pop them back on your head, and the music resumes. Bowers & Wilkins aren't the only company to integrate this kind of technology - Plantronics' Voyager 8200 UC headphones do the same thing - but B&W have seemingly perfected it.

Other plus points include the build quality - which also extends to the carry pouch - the incredible battery life (22 hours), the easy-to-use app, and the .

Things We Didn't Like

Bowers & Wilkins PX Wireless Headphones

Comfort, comfort, comfort. Due to the weight in the ears, it would be hard to imagine wearing these for lengthy periods of time, which is one of the reasons why I fell in love with the P5s. Some will find the weight reassuring - especially from a durability perspective - but I kinda wished they'd shaved off some grams somewhere along the line.

Is It Worth The Money?

The closest comparison I can make to the PXs are the aforementioned Voyager 8200 UC headphones, which are currently £40 more expensive. For that jump, you get less battery life, a flatter soundstage, and an uglier design. In a straight fight between these two, you know where our money would go.

You can purchase these headphones by heading here. They retail for £329.
