Q Media - Q. Why is the volume low when playing music from my iPhone/iPad via Bluetooth?
Answer:
There may be some settings which you
might need to adjust within your Apple device, which we have found
within
this Apple thread.
Settings > Music > Volume Limit
Settings > Music > Sound Check
Settings > Music > EQ
Another thing which you could try is to forget the pairing on your iPhone/iPad and try to pair again, to see whether this helps.
We would also suggest closing and re-opening any of your music-based apps once you have made any changes.
