Usually a sub will have its own separate physical volume control, but not so with this one. Great for protecting mesh from hair dirt and sweat when working out. since its lightweight, I could wear it for hours without fatigue/pain. Its very fluffy and your head sinks in like its made of clouds, and by overstuffing it you gain the same support you would from a high quality memory foam pillow. I’ve heard this is not uncommon, so I can’t recommend this battery. This wireless unit beats all my previous Bluetooth earbuds! I decided to go for a pair of over the ears instead. They look great and are easy to install IF you have installed towel bars before. Bargain price but the sandals were shipped in a plain box not the original, No receipt nothing except just the sandals inside the box and the insoles were out of the sandals they were not attached inside. I got this rack because my cabinets are really small.
