I should have known, it doesnt work with my headset, or any OTHER headset I try - and yes, i have a few. It is also nice to have extras, just in case. Now have $300 paper weights- I should have saved money and bought airpods! (I was even prideful enough to imagine that itd be a natural fit for me because Ive used, and liked, Wen, another pretty finicky product, for years. Also to use the clip to be able to attach the case to my backpack. don?t waste people?s time. After constant use, after a few months the flap doesnt remain up. Where to begin! I think you will be also. Really impressed with the quality.
