The bleed from them is really low; you can only them on full volume when you are about a foot away. Cons:When the battery is low it gets annoying. Later this evening after washing the towels. I also use them in cafes etc were people are talking and I need to concentrate. I am not that handy, so it is obviously easy to assemble. We are reorganizing a number of family photos - couldnt be happier with this product. We use this for our two barbells (45lb and 35lbs). These sandals are soft and lightweight, I love them! Got a teeny bit loose on the handlebar but will have my son in law tighten for me. Third mix amp was broke and couldn’t control volume.
