Its very comfortable! These are well-built, easy to get on and off, and easy to adjust. I saw this Buzzrack and it had almost all the features I was looking for but was much cheaper than most others. I did watch a couple videos and read more and was able to get them installed, but def not easy. Invalid. ?” every 30 seconds. There are so many fake reviews on Amazon and particularly for earbuds, that it is really hard to give any credence to Amazon reviews any more. It took me a long time to find the piece for this little wall and this is it! This means every time you turn the headset on, every time you leave and return into range, if you do not have the microphone plugged into the side of the headset, it will MUTE your microphone. 5-9 but med fits.
