I won't get into whether or not it works on a technical level or not, as I haven't had this for more than a day. But it's an awful lanyard design, if you're the type that doesn't feel like wearing it in your ear all day. really no way to clip this to something, instead you've got to have a 3" string hanging from it that then has a loop on it, so you look like you're wearing some kind of idiot pirate earring or something. And that ring and the necklace that ship with the earpiece are such that you can't quickly or easily detach the headset from said necklace.Anybody want to buy a new (packaging opened but device not used for more than 5 minutes) HBH-PV705 cheap?
