Hi everyone,
I’m having trouble calling with my MTW3 (Momentum True Wireless 3) earbuds when connected to my Xiaomi 11T (MIUI Global 14.0.4). When my MTW3 (Sennheiser Momentum True Wireless 3) is connected to my Xiaomi 11T and I want to call I get a really loud humming/static/buzzing sound. This starts with pressing to call (right after pressing the green telephone button), the other person doesn’t need to answer the call for the problem to occur. When the other person accepts the call I can’t hear them, they can’t hear me. When I enter a call in Discord the same happens.
I tried connecting the headset to my girlfriends phone (iPhone) and the problem does not occur. I also tried connecting a different (QCY-T5 Pro) headset to my phone and the problem does not occur. The problem seems to be the way the Xiaomi 11T and the MTW3 connect to eachother. A replacement pair of MTW3's and a phone factory reset did not solve the issue.
Thank you for your time and help in advance!
