Comfortable and good sound quality They do have a sound to them when there is nothing attached and you are on the highway perhaps from the wind catching it. So I am able to charge my watch, phone and air pods and only use one outlet! You could cork a jug with one. Runs slightly small. The sizes are fairly generous. For fans, this is the culmination of a 12-year wait and its a no-brainer. I love the bling bling. Upon arrival of the CCA-C10 though, they realized that it had taken the place of the ZSN as better and well worth the price difference. Ive avoided writing a review for this product because I have mixed feelings for it, but have just decided to be honest about my experience with them.
