I bought Sony WH-CH720s two months ago and it's really pissing me off. The headset shuts off automatically after half an hour even when I'm using it. I checked the settings but I can't find an option to disable it. Is there some trick I'm missing or is it actually a defect?
No, that's not normal, the WH-CH720s don't have any auto shutoff programmed after 30 minutes. You probably have an "Auto Power Off" feature that got turned on somewhere - check the Sony Headphones Connect app, that's where you can adjust the auto shutoff (it's usually set to 30 minutes by default). If it's already disabled in there or you can't find the app, try resetting the headphones by putting them back to factory settings (hold down the Power button for like 10 seconds) then reconnect everything. If that doesn't change anything, it might be a hardware defect and then you should check your warranty because two months is pretty recent.
It's weird because normally Sony WH-CH720s go into standby after 15 or 30 min of inactivity, but not when you're actively using them 🤔 Check that the pairing with your phone is solid and it's not coming from a bluetooth disconnect? Otherwise it really looks like a defect - you still have warranty after two months, I'd try exchanging it with the seller or Sony directly, it's definitely not normal for it to cut out while you're using it.
First check if your battery is actually fully charged - it might sound silly but a weak battery sometimes causes early shutdowns. Otherwise, uninstall and reinstall the Sony Headphones Connect app, that often resets the default settings and fixes weird stuff like this. If it keeps happening after that, it's probably a hardware defect and you should use the warranty.
