Sony has thrown everything it can into these much smaller earbuds, and given us an extra set of foam tips so they fit perfectly. LDAC, the firm's top-tier DSEE upscaler, and Bluetooth 5.3 are all here, battery life is competitive, and the sound is 100% bona fide Sony quality. However, for us, connectivity drop-outs, average ANC performance, and an app that looks a little busy at this flagship level add up.
Agile, meaty and fun listen; Very comfortable and secure earpieces; Battery life maintained from XM4
ANC can be beaten; Occasional connectivity issues; On-ear volume control is a tad hit and miss
