I have struggled to find something comfortable to wear easy to charge and seamless to operate in a headset for years. I listen to audio, mostly spoken word, a lot and this unit is absolutely brilliant for that. The audio is clear, precise and also the design means that I can still hear things happening around me. The unit is comfortable even while I am wearing glasses. The battery life is a solid 7 hours for me. The charging case works wonderfully and I do not have to fiddle jiggle or generally manipulate things to make it work (unlike other units I have worked with). I have found that the microphone suits me to a t.All in all I have not found any downsides for myself. The unit is comfortable to wear even given the large form factor. I am told I have a large skull so take that as you will. It even fits comfortably whilst I am wearing a hat.
