Q: Works fine but sound is tinny and flat, absolutely not useful for music, devoid of any bass or depth, any size Bluetooth speaker I've used for a phone or mobile device is better, should have stuck with that. Paid too much, expected too much, looking forward to upgrading soon.
A:
Tinny sound, use a bluetooth speaker or go with something higher quality
