The Sony WH-1000XM4 deliver excellent noise-cancellation and surprising sound quality all in a lightweight, comfortable design.
While they don’t look significantly different from their predecessors, the Sony WH-1000XM3, a number of new features including multipoint pairing, DSEE Extreme upscaling, conversational awareness and auto-play/pause using a built-in sensor all help the WH-1000XM4 claim the title of best headphones in 2021.
By every possible metric, the Sony WH-1000XM4 is a wonderful pair of wireless noise-cancelling headphones. They deliver exactly what they promise and then some thanks to their exceptional noise cancellation and cutting-edge codec support.
On top of the adjustments listed above, the Sony WH-1000XM4 support Sony’s 360 Reality Audio format that enables spatial audio on stereo headphones plus the LDAC codec that can send a bitrate of up to 990 kbps. The unfortunate bit there, though, is that it no longer supports aptX or aptX HD, so your Hi-Res Audio support mileage may vary.
