Razer Kraken Kitty BT Edition Headset no Sound when Mic on

Hi there, I bought my wife the Razer Kraken Kitty BT Quartz Edition and I have now following problem on different PC's and the Firmware is Up to date and all BT driver on the PC's also. I start the Headset. I pair the Headset via Windows. When its paired it says for Output: Razer Kraken BT Kitty Edition Stereo (Standard Device) Razer Kraken BT Kitty Edition Hands - Free For Input only: Razer Kraken BT Kitty Edition Hands - Free When she is only listening to Music / Ingame Sound everything is fine. But when she needs to use the Microfon the Sound turns off. It doesnt matter if this is Discord, Ingame - Voice or even a Microsoft Service / Sound-Mixer overview. When the Output is then changed to Razer Kraken BT Kitty Edition Hands - Free sound appears but tbh. it sounds like a Stream which is very low on Qualitiy and have lot of interferecnes and like the Sound is comming from the backgroudn etc. Well it sounds like sh*t. When the Microfon is not used anymore in 90% of all cases the Headset switch back to Razer Kraken BT Kitty Edition Stereo with good sound in 10% of all cases it sounds like a mix between the good and the sh*t sounds which make it sh*t at all. I see the issue is somewhere in the driver for this headset or even the headset itself The sound also turns off when I am in the Soundmixer and switch from Output to Input tap because the mic get activated for this. Some Screenshots: https://i.imgur.com/9RT8gBl.png overview Output https://i.imgur.com/gkILTs5.png overview Output Mixer https://i.imgur.com/hgPCupJ.png overview Input Mixer (when i switch here its get deactivated) As you can see in the Screenshots for the Inputmixer the Headset only installed the Hands-Free stuff. When I disconnect the Hands-Free stuff the Stereo works fine but no Microfon availible.
