It definitely deserves a place on the list.

In fact, it's the worst of the worst, since it's just plausible looking enough to be the only option on over a billion devices.

On top of that, the EU passed a bill to make them fix it, and they... didn't. If you have headphones that are too loud at 'unit above zero', and use the volume limiter in the device safety section to set it to a reasonable level, it just completely mutes the headphones.

This isn't a hardware issue. Bluetooth devices have an integer volume setting, and the "unit above zero" setting is definitely not '1' on iOS like it is on android.

I've hit this problem with 100% of the non-apple headphones I've used.
