Very comfortableArrived earlier than expected ***Update. The one caveat I have about them is that they are not leather-lined so they can get a little sweaty after a long day. Gift The sound is just as good with a small 12v battery as it is plugged into a wall outlet. I like that the item fits really good and that it makes you sweat and also it holds its water In the second one I built I left the permanent shelf out so I could fit taller items such as my broom and folding grocery cart. Completely recommend. They give me the support I need for water aerobics, and I love how they look! In addition to that, the sound quality is just amazing.
