Thanks for writing to the community.
I am very sorry to hear that you are experiencing some issues with the Bass response of your SoundLink Revolve Speaker.
Can you confirm that you performed a reset by the following instruction.
Have you recently moved your speaker to a new location which could potentially impact the Bass response of your product?
Please let us know.

I'm experiencing the same issue. Definately a reduction in bass with the latest firmware udpate. It seems like Bose possibly tried to improve sound quality for phone calls (maybe by reducing bass) but these changes have had a big impact on music playback. If that was the intent, they need to have two seperate audio profiles, one for music playback and one for conference/phone calls.

Try a 'Master Reset' by pressing and holding down the power button for approximately 10 seconds.
This worked for me, the bass and richness of sound is back, actually sounds better than before the firmware update 🙂

I have Bose Revolve Plus as well and it sound worst on the base after the firmware update to 3.0.4 now. The rich deep base sound is no longer happen. I did perform the 10 second reset as you provide below but it does not help. Can we reverse the update in anyway. Please help and relate this to your R&D if a another new update is possible?
