annoying! It works on the plane nicely and no more buzz sound in the ears while flying)*And it’s wireless! It worked great with my Wahoo Bolt and Niterider Lumina 850 light. battery life around 12 hours in 50% volume and 5 to 6 hours in 90% volume. Very dissapointed & can not recomend. To honest I like these shoes. I am able to do my full work out including my ab exercises in this and the previous waist trainer I had I could barely move in it. Its not Amazons fault they just ship it but who ever they get this junk from is really slacking on the checking things before they go out. Lo compré cómo renovado y los audífonos se los ve prácticamente nuevos y la conectividad muy buena, funcionan perfectamente con la Nvidia SHIELD TV y con un celular se los puede usar usando un adaptador OTG de micro USB a USB, y cabe decir que la calidad del sonido es excelente. Flojos I might go to flip-flop you cant go wrong very comfortable.
