I am very pleased with the BTD500. Unlike all Bluetooth dongles are here to have a sound card that automatically tries to connect on Bluetooth receiver. This works without any software (there is not) and therefore under Windows and Linux (8.1, 7 and Ubuntu tested). A Blessing is the uncomplicated use and even if the stick is he plays the next boot straight on. Between PC and laptop "move" I'm constantly and it all works great. Button He has also no plug for coupling it is necessary to highest off and on again. After all disappointing BT dongle that then but gave only poor sound, finally a great-sounding solution (but unfortunately I could Apt-X receiver is not for lack of trying).
