Galaxy s6 Bluetooth Audio Volume is Low

[GeorgeHarry]

Anyone know why the Bluetooth Audio to my Galaxy s6 is low? Even if I put the volume all the way up on my phone it still plays lower. I"ll play the same song on my s5 as I do on my s6 and the volume is significantly lower on the s6.

What Bluetooth device are you using with it? Does it have its own volume control?
