Our verdict: Sony WF-1000XM4 review

Sony is debuting its new Integrated Processor V1 with the WF-1000XM4. This, in tandem with the dual-noise sensor microphones, further quiet low-frequency sounds like the drum of a plane or car engine. Provisions include an array of memory foam ear tips. Anyone who struggles to find the proper tips can use the Sony Headphones Connect app (free on iOS and Android) to take an ear tip fit test. It gives you immediate feedback about your selection and ensures that the earbuds block out the most amount of background noise possible.

An IPX4 rating means moisture like sweat and rain shouldn’t damage your earphones.

The Sony WF-1000XM4 support the LDAC high-quality Bluetooth codec, remedying one of the more curious omissions of the previous model. If your music streaming service doesn’t support LDAC transmission rates, you’ll benefit from the DSEE Extreme processing that upscales compressed music files for clearer, more accurate sound quality. Of course, the buds also support SBC and AAC as well so you won’t be left high and dry if your phone doesn’t support Sony’s high-bitrate codec.
