Bose S1 Pro 




Firmware Version

What devices were you using that were affected and what version are they on (e.g. Samsung Galaxy S9 on Android 11, iPhone X on iOS14, etc.)


We set up both S1 Pros side by side. Tried the SM 58 in mine with max volume and then tried the same SM 58 in his. His was clearly much louder.


What environment do you experience the issue in? (e.g. noisy office, quiet kitchen, etc.)


When did you start to experience the issue? Did it work correctly previously?
