I have had some YouTube-worthy moments before with my cords getting tangled up when trying to switch when my phone rang. The headset is comfortable and when it works it sounds great. They quickly responded to my e-mail regarding my sizing dilemma and will be helping to rectify the issue. Cons:Not MFi device so no “hearing aid” functionality. 5 and fits perfect. The toe thong is very uncomfortable as well. My 12 year old daughter says she likes the style for when playing things like Tetris. So they deserve it. They did stretch a little making them even more comfortable to wear. I experienced clear, loud, powerful sound with Mega Bass turned on.
