The "speakers" sat over your ears, rather than having inner ear buds, and they lasted forever. Strong, easy to install and perfect for 2 guitars and a few odds and ends. I bought them for a babys nursery room decor. I am not sure if it is hardware or software issue. They were a little tight when I first put them on but by the end of the day they were a perfect fit. When battery gets low it emits a loud chirp that you do NOT want to hear wearing the headband. But only a year after you bought them? Really? Come on. Neon Blue Y-Shaped strap is the MAIN REASON that I choose this unique Emporio Armani slipper (Not Black Y-Shaped Strap). This is totally new technology to me. Over time, with the use of really good sneakers that are specifically for plantar fasciitis, my planter tendons have healed.
