It took several times to plug in the charging cable before the red charging light came on. They?re not bone conduction. This refurbed mouse has a dead zone halfway down the click so you have to click either VERY hard or VERY soft. Sound quality amazing! In addition, the front wheel rest in the cradle. Super light, comfortable, stylish, and great in the water. Great for cleaning pets ears, just be careful you dont go in too far. Like Truvy (Dolly) in Steel Magnolias: in a good shoe I wear a size 9 but an 8. I will update once I have worn them as to how comfortable they are to work in. I also like that they come with a carrying case and they are magnetic so they dont get tangled.
