I like how the zipper is under a flap to keep water out. Installation is fairly easy but kind of a pain in the but. I tried a $75 model with a single driver and ended up sending that back because the bass - lower mids were less than half the volume as the highs. Pillow # 7 is the Beauty Life Solutions shredded memory foam pillow. The second day I wore them, two strands of beading became mostly disconnected, & I had to cut it off eventually so I wasn’t walking around with flapping bead strands. I’ll charge them. Cool looking but that means nothing if they do not work and that was the reality. Bought the 5-6 size. One apparently had a manufacturing defect as one end came apart while I was attaching it to my boat. Now Im not sure now long they will last but so far, so good.
