I never typically wear headphones more than an hour or two and have never had any discomfort for that time period. The zip is controlled just by a tied on piece of thread, and the actual zip is flimsy and catches. Although I was in no hurry to assemble them it took maybe an hour each. After seeing the BearPaws today, I thought of contacting Amazon. Finally I have some descent organization of my spices that doesn’t take up a lot of room and I can quickly access the spices even as I’m in the middle of cooking on the stove. However they are gigantic and will not stay in mine or my husbands ears, and the battery life is so short lived that if youre a hiker or enjoy doing outdoor activities for longer than 2ish hours you wouldnt be able to use them the whole time. You can easily see quite quickly where it stands. They hide your tummy so well but still manage to be light weight and comfortable! Connectivity is fantastic - so is the microphone so these headphones are fantastic for long webinars and conference calls - you’ll be heard when you speak, and not sound at all muffled. Just needed a hang my bike on the garage wall.
