Sony WI-XB400 Wireless Neckband Headphones

Sony WI-XB400 are lightweight behind-the-neck wireless in-ear headphones with extra bass, up to 15 hours playback, and USB-C quick charge for on-the-go music and clear hands-free calls.

The Sony WI-XB400 combines extra-bass tuned 12 mm drivers with a flexible neckband and magnetic buds to deliver comfortable, portable sound for daily use.

How does the sound quality perform for music and podcasts?

The WI-XB400 focuses on punchy low-end response from its 12 mm drivers to emphasize rhythm and impact, while still delivering clear mids for voices. You’ll hear a warm, bass-forward signature that suits upbeat genres and spoken-word content alike.

• 12 mm driver units for enhanced low-frequency reproduction
