Hey everyone! I'm having an issue with my Sennheiser 458BT headphones - they sound way too quiet when I'm using Bluetooth. I have to crank the volume up to about 26% just to hear anything clearly. In wired mode, the sound is perfectly fine, which is great, but since I rely on noise cancelling due to being autistic, I really need to fix the Bluetooth issue. I've already tried a few things: switching the headphones between my laptop and phone, checking for the latest firmware, and doing a reset. Unfortunately, none of these worked. I'm worried that if I can't sort this out, I'll have to sell them and look for another pair with better noise cancelling. Any advice on what else I can do to fix the low volume problem in Bluetooth mode would be super appreciated! Thanks!

Have you tried enabling Developer Mode on your device and toggling the 'Disable A2DP audio hardware offload' option? It might help boost your Bluetooth audio volume. Just go to Settings, tap on About, and hit the build version 7 times to unlock Developer Mode. Once you're in, give it a try and reboot your device!

I tried that, but I couldn't find the 'Disable A2DP audio hardware offload' option on my OnePlus 13. Any other suggestions?
