Different bikes, devices, and applications are going to output different levels of sounds and volumes.
There is only one way to adjust volume on the 20s.
You can easily adjust the volume by rotating the Jog Dial. You will hear
a beep when the volume reaches the maximum or minimum level. The
volume is set and maintained independently at different levels for
each audio source even when you reboot the headset. For example,
once you set the volume for mobile phone handsfree, it will not change
even if you adjust the volume for your Bluetooth MP3 music. However,
if you adjust the volume during stand-by mode, it will affect volume
levels of every audio source.
Other than this you can enable AUDIO BOOST and Noise Control from the configuration menu settings.
We do appreciate you bringing this to our attention. We'll use your valuable feedback to evaluate the kinds of issues with the devices and wants our consumers want in the products especially with more volume.
I apologize again for any inconvenience.
Please submit your great ideas here as feature requests, so our engineers can look into this more in depth:
Thanks and have a wonderful day!

This great idea have been submitted several times already.
It would be wonderful if I can set up the volume independently at different levels for
each audio source even when I reboot the headset as a base level and software can increase this level based on the amount of ambient noise.
Is it so difficult to change software to make it possible?
With best regards, Alexey
