I'd think that if the reseller sold the device as being capable of working with bluetooth v4 and the A2DP profile, only for that not to be the case, then you absolutely have the right to take it up with them. Surely by their not advertising the dongle limitation, that's a problem of their own making & they should honour your return. If they've a problem with that, they take it up with Jabra but leave you out of it. After all, you've got a device that speaks Bluetooth so you've got something that the product declares it'll be compatible with, and the product just.. Isn't!
