Syllable E3 multi-functional Bluetooth Box Transmitter 3.5mm Bluetooth 4.0 receiver dongle adapter box For computer TV audio adapter Launcher
When I purchased the item it was labeled as a Bluetooth 4.0 transmitter and receiver.  When it didn't function as a receiver I contacted SEVESTO. They said it was a mistake and refunded me half.  It really didn't work too well as a transmitter with all of the cutting out.  Ended up returning it for a full refund.
