I hope this will be implemented at some point in the future. Just having the option to toggle it in software would be super useful to people who don't use sidetone such as myself. As of now I have to fine-tune volume in software which kinda defeats the point of having the volume wheel.

I also was very disappointed with the hiss until I realised that the sidetone toggle only takes effect when the headset is plugged in via USB. After turning it off the hiss was barely noticeable with nothing playing.

Made an account just to say that I have this imbalance issue on my pair too. Getting it sent back to my retailer to hopefully get a replacement pair without the issue. I'm certain it was a driver issue as the imbalance (left side louder, right side quieter) flipped when I flipped the headphones...
