I have had this device before and purchased this one because my old one was not machine washable (forgot to was in my pocket ooops). I have had many bluetooth ear pieces, some very expensive, some not so but for functionality and comfort this one wins hands down for me.

great sound

Yes very good

One of the worst Bluetooth I have ever been use. Highly not recommend please dont buy

Had a model before this one was better range n better volume

Great battery life
