Bluetooth Audio - Quieter?

[HelixOmnimedia]

Hey,

Download the public beta last week and over the weekend been listening to podcasts, but today was listening to music and I couldn't help feel that the sound was a lot quieter.

Am I going mad or is there a noticeable different from iOS9 > 10.

you are not alone. I've the same issue with my bluetooth headset. Sometimes it comes back to the normal level after reconnect the headset or reboot of the handset. I've no clear picture about this issue in the moment.
BTW: this is also discussed here
