Sony WH-1000XM4 Wireless vs Sonos Ace Wireless

Both the Sony WH-1000XM4 Wireless and the Sonos Ace are top-of-the-line headphones. While both headphones have a premium build quality and first-class noise isolation performance, the Sony are a bit older but still offer good value as they're more customizable, thanks to their companion app, which has a graphic EQ and virtual soundstage at your fingertips. They also have a longer continuous battery life and can be used passively. They also support LDAC for high-quality audio via Bluetooth, although the Sonos have aptX Adaptive, aptX Lossless, plus USB audio support. That said, the Sonos are more comfortable and have a TV Audio Swap feature that you can use with compatible Sonos soundbars to receive audio from your soundbar. Some users have reported issues using the app, which can be a dealbreaker, though.
