I have done the update however unfortunately I think this firmware is a step-backwards, particularly for audio quality.
I have been using the SoundGuys EQ which sounded fantastic on the prior firmware however on the latest update the volume is noticeably quieter and the bass impact has reduced also.
I know there were some reports of distortion at higher volumes however most found that this was related to having the headphones properly seated.
I think these headphones top volume was already on the quieter side however this is even more so now with the latest update.
Is it possible to roll-back to the prior firmware at all?
