I have exactly the same experience. Usually my friends are having hard time hearing me because my voice is so distant and muffled. This is a bit awkward as I hyped these headphones to them before buying and now I'm the one with crappy headset even tough other guys are running 10 times cheaper headsets. I use sidetone and my own voice sounds really good from my own headphones. So the actual mic is really good quality. But something has gone really bad with software and/or the wireless connection/dongle. I haven't been able to get this mic connection to go from bad to better but it seems to go from good to worse if you happen to connect the headphones to a bluetooth device. For example when I connected to my android phone to adjust the headphones, the mic broadcast quality dropped instantly. But I couldn't get it back to ok by shutting down bluetooth or turning off and on the headset. I've heard that restarting the console could do the trick but haven't been able to confirm that just yet. Maybe just disconnecting the dongle and reconnecting would do the job. That's what I'll try today.
It's really sad that as Audeze seems to be really good at making headphones but they always make some crucial mistakes when designing gaming headsets. For example now they've had to compromise between good mic broadcasting quality and good audio quality because they are using only 2,4 Ghz dongle. Now the wireless bandwidth isn't just up to get the best of both worlds. For example Astro uses 5 Ghz wireless network so they are able to use a lot more bandwidth. Usually 2,4 GHz network is at least stronger than 5 GHz but for some reason the Audeze's wireless is really weak even tough they don't have enough speed in sense of bandwidth (at least it's not laggy). Now people are complaining about connection problems and bad mic quality which both wouldn't be issues if they had used strong and fast enough wireless for good quality audio. So they wasted money on a "broadcast quality" mic which you can only listen by yourself but saved money in the wireless dongle. That's really bad design problem and I bet they will release new set with better wireless in 1 or 2 years.
There is still hope that they could do something about this. At least considering the mic. If they manage to pull of really good software solution, they should be able to fix it so that the mic quality will be ok. Now they are trying to use just certain frequencies and probably pack the data. But the gaming consoles or games them selves might just pack the data once again process the signal once again. So if you ad some software bugs to that it would be amazing if the result would be satisfying. I really hope that they will find the solution for this problem and that the solution will not decrease audio quality.
