I will be returning because I do a lot of squats and deadlifts and dont want anyone to be looking. 5 in adidas and most other shoes, with the exception of hiking boots/shoes, which I go up to a 9 for extra room. I chose not to put the handle on because of space restrictions. Ive tried several different types of earbuds and these are by far the most comfortable. It?s fits just right but nothing even remotely extra. The first signs of wear Ive noticed after a year, the top middle section of the silicone "strap" started cracking, because I always have to stretch it back, away from notification bar of the phone - it seems I have an older model, as they show on photos with straight top and bottom, while new model has an arc (highlighted in green)But I dont worry about it, even when it eventually fails, based on my experience with other silicon mounts of this type it wont make phone fall out, in fact failing any The only positive is that the sound quality does live up to its hype. One con is I wished these were louder, but thats expected from a 12W speaker. If you are having problems connecting, just go to YouTube, search for the video and follow the directions very carefully. Bluetooth pairing: Easy and fast.
