Question about Bowers & Wilkins px

Bose has better noise cancellation, but the PX sounds much better.

Google this topic - there are very good test comparisons, some in English. The result is always the same: purely a matter of taste for the testers. PX, Sony, Bose are on the same high level - but each part has its differentiating features and you buy what is important to you. You can't really go wrong. For me, for example, the USB-C connection, the super functioning sensors, the great iOS app and the noise cancellation were the criteria that spoke in favour of the PX. I am totally happy with this product and would buy it again.

I have compared both and can only agree: The PX achieved the best result in terms of sound, design, quality of the headphones in terms of workmanship and materials. The battery life is also exceptionally good. The noise cancellation is a bit better with the Bose. The Sony has a bit more bass.
If you like a high-quality sound experience, you should go for the PX in my opinion. But wearing comfort is also important and that's why I would advise you to try out all your favourites.

If you're looking for great sound, I think the PX is the only one that sounds really good and high resolution. But it's always a bit subjective. I don't feel that way myself, but some testers say the PX is quite heavy. Colleagues of mine who have the other two also said that. But that's also subjective.
