I wanted a lot of bass to come with these headphones. The "height" of the earphones adjusts very smoothly and they have a premium feel in general. The night prior i had some family help looking at it trying to figure out what it was we needed to do. Love it, feels soft and looks sexy, I recommend it ?? % PROS:- Fast, responsive- Very long Battery Life- Looks greatCONS:- God forbid you need support- Will stop working and you will not have an easy avenue to fix it Other waist trainers I?ve worn in the past left my skin tingling and irritated. I purchased 2 of these, and they came impressively packaged for safe handling during transport to prevent breaking of the jars. Will probably order another color! I?ve worn next slipper flip flop years, which are considerably cheaper and last for months. It began getting sticky and mushy til it had a noticeable stick when clicked.
