And for those who say you can’t get a screwdriver in there or you may have to use a regular screwdriver to tighten it instead of your drill With the screws are shorter than my last shelving unit and easy to do. Not very pleased with this purchase! The flex material inside is a band that stretches as it grips your head. Amazing product for the price. Responds to equalizers well if you wish to use one The controls work great, which surprised me being that they are touch like the JLab. My pixel phone require 18W USB-C charger to enable fast charger and I require an extra charger to be used at work.

Sweat a lot in it due to tightness and fabric. Fila’s memory foam shoes used to be my favorite because they were so comfortable and cushioned my feet.
