Sony makes some of the best wireless headphones around, especially when it comes to noise-canceling models. This material fits snugly around the head with less pressure on the ears while keeping out external sounds. LDAC transmits approximately three times more data (at the maximum transfer rate of 990kbps) than conventional BLUETOOTH audio, allowing you to enjoy High-Resolution Audio content in exceptional quality as close as possible to that of a dedicated wired connection. From airplane noise to people’s voices, our WH-1000XM5 wireless headphones with multiple microphone noise cancelling keep out more high and mid frequency sounds than ever.
