After finding that many Bluetooth headphones had functions or features that proved to be complicated, these headphones are straightforward to use from the start, with built-in features you can manage via an app rather than on the headphones themselves. Would definitely recommend for anyone looking for a straight-forward pair of Bluetooth headphones with great sound quality.

Ive been using noise cancelling headphones for a few years (Plantronics Backbeat Pro), and upgraded to these ones. The jump in active noise cancelling performance between these is absolutely stunning. Peoples voices turn into a quiet barely audible tinny sound (far, far superior to the BB's), and background hum is utterly gone. The first words out of my mouth when hearing the noise cancelling performance while people were speaking…well, they cannot be repeated here. Lets just say, im very impressed. Music performance is good, not too bass heavy. The reviews are right, these are the best out there.

NEW DELHI: As far as consumer audio products are concerned, Sony’s 1000XM series never fails to impress. But the problem with updating any consumer electronics product on a yearly basis is that you run out of ways to make them better. With the WH-1000XM4, Sony faces that uphill battle.

Sony has refreshed its flagship wireless headphones this year, though you will be forgiven if you mistake the XM4s for a rehash of the XM3. Taking a “don’t fix it unless it’s broken” approach, Sony didn’t set out to fully remake the headphones.
