(I would blame the tablet if none of my other Bluetooth headphones, IEMs and over-the-ears, had this problem. I did not even get to take them out of the box first. I sent them back immediately. The left side is slightly tight and the right side is way too loose. They are very comfortable to sleep in. In our camper where storage comes at a premium, these spice organisers work perfect for spices and other small items. I bought the rack to hold one bike and a step ladder. They broke within one day. I just purchased 2 of these headsets and the headset splitters since the "notes" section copied below :Notes:1. These are perfect- no water on the floor and they dry quickly.
