Only downside is that it feels a little fragile so I will have to careful with it. Is going heavy on pulls far easier without dealing with grip problems? Absolutely. I have to unplug and replug several times and play with the cord to get it to work again. looks like Ups reTaped the box as it was delayed a day. After about ten minutes without any audio and they automatically power off. Really easy to set up and Ive had no problem with it connecting/staying connected with my phone while out walking (phone in the stroller). If this cincher had fit a little better, I probably would have kept it because it made my waist feel and look slimmer. I thought "hey, maybe I was just unlucky with a malfunctioning one". I hope these stay together longer as the bottom on the last 2 pairs became unglued in just a few seasons use. Lo que pudiera ser un punto negativo es el tamaño del estuche y los audífonos , son muy grandes , pero no se podría tener mucha batería si fueran pequeños.
