I thought it might be a single defective product so I decided to ask for a replacement and to my surprise it started making the sound straight away. I recommend these headsets. Far too small for HyperX Cloud II headphones and do not fit at all. Even doing that, they made it for a year pulling double duty as my river kayaking/fishing shoes and casual everyday stompers. They are padded really well both on the soles and around the entire shoe so no blisters. They are slightly large in length only but it doesnt really bother me bc the rest fits perfectly and my toes are very cushioned. Feels like a sneaker. But besides that I’m gonna start running with it on so hopefully it will trim down my waist. This seems to be a far superior way to charge. I tested the mic with friends as well as via a playback and its very, very clear without backgrouns noise, crackling or static.
