I bought a pair of madden girl bryceee about a year ago and wore them standing 5-7 hours at a time, 5 days a week at work. I bragged about you Corsair, i have your H110i, commander pro, Void Pro, ML140sThis is a big let down, only lasted 1. But, if you recognise that you click “send activation code” and they email you one seconds later, then you type that in and click “activate”, you’ll be fine. They are so convenient and stylish! Using these much more often than my AirPods. Highly functional with the different shaker heads built in. 4- The volume and function button work great with my phone. The flashing LED is pretty extreme; it would be great to be able to disable the LED. They are a bit fuzzy and have what feels like memory foam. Returned and will not re-order.
