Good sound but problematic Bluetooth connection - It is frequently difficult to get the Bluetooth connection established with these phones. It was not so with the previous phones we had. When the connection is finally established, the phones work okay and give good sound.

BRINTONMOct 23, 2026 · Verified purchase ★★★★☆

Sony WH-CH250 Headphones - I use it everyday, has really long battery life but when I get calls the audio distorts and sounds like it's playing outside if the headphones and grainy. I do feel like they fall off easily, I use them during warm ups before practice and they've either almost fallen off or entirely fallen off at least 5-6 times. Aside from that, I really do like them.

Comfortable headphone. My kids like it!! They always take them along—to school, when we go somewhere, for listening to music, doing homework, and so on.
