Jaybird English (US, UK, AU, NZ, CAN)

Good sound. Like the addition of the equalizer function on the app.

Sound is good, with App options, sometimes scratchy with static, not had issue with X3 model. Firmware update may be issue?? Fit options and receiver pickup great. Thanks

Great sound quality, even when working out and running around ambient noise. Good fit, doesn't slip much. Only complaint is that they sometimes cut out randomly during songs/podcasts, takes ~10s to resolve itself each time and happens ~every 10 minutes. Would still recommend!

Great deal got them very quickly

Battery life improved but for the money it should. I do lose signal from time to time. Overall one of the best...but then again one of the most expensive!
