The Tao Plantronics Bluetooth Stereo Transmitter came in a sturdy box with lid. The scope of supply also has a charging cable with Micro USB and USB connection (ca. 100 cm), a plug adapter with two RCA connectors (20 cm) and a multilingual, comprehensive and easily understandable instructions for use. The Bluetooth transmitter has the dimensions 5x2x0,8 cm, which is less than so maches lighter. The housing consists of a high quality plastic with a velvety surface and securely holds each fall from. Is the multi-function button on the narrow side. There is a micro USB jack of 3.5 mm jack plug on a 7 cm long cable and a LED indicator on the front side. Having the transmitter charging about 4 hours I could try it on a 15-year-old TV set, an approximately 3-year-old TV set, an 18-year-old stereo and an I-Pod. As a receiver I used a wireless stereo headset from TaoTronics. A Bluetooth speakers would also be possible as a receiver. The transfer went smoothly with all appliances. On the flat screen TV I could see the transmitter even connected to the USB cable and charge it at the same time. The manufacturer requests so explicitly, because the device is protected against overcharging. Distances between transmitters and receivers up to 5-6 meters are no problem. The small device works stöhrungsfrei and is my z. T. older equipment easily compatible. Therefore the TaoTronics Bluetooth Stereo Transmitter gets me the full purchase recommendation.
