Hi all,

Yesterday, I received my order of the Sony MDR-ZX770BN bluetooth headphones. After using them for a while, I realised that the volume control on the headphones control the bluetooth volume, whilst the iPhone's volume controls (buttons, slider, etc.) control the music volume. The bluetooth volume and music volume are independent from each other, i.e. one could be max volume and the other could be low volume and the bluetooth headphones will take an average of the volumes.

Is there any way to disable the iPhone' bluetooth volume and force the headphones to use the music volume instead?

Thank you!

Not that I know of. In this situation, I max out the iPhone volume and use the headphone volume control to go up or down. This function is headphone manufacturer-dependent I believe.

What the volume buttons do on the iPhone depends on what app is active and on what is connected. I'm almost sure that when your BT headphones are connected and you're in the Music app, there's only one volume that is adjustable related to the iPhone music. If you adjust the volume on the headset and it doesn't change the volume you see on the iPhone, then it is independent from the iPhone and just attenuates the signal from the iPhone.

If this is the case, you'll probably get the best sound if you turn the volume on your headset all the way up and use the iPhone for adjustments. Extra attenuation on the signal, in many cases, affects equalization. If the headset volume is independent it is still handy for quick adjustments when needed.
