 USB Bluetooth Audio Transmitter

 Avantree leaf

  1. Features & AptX Low Latency

 Avantree leaf is a Bluetooth audio transmitter incorporating the latest “AptX low latency” technology, for CD-like quality sound with virtually no delay. Ideal for games, watching movies on PC/iMac without lip sync delay. Also, with multipoint support, you can share the fun and enjoyment of audio with others.

 Aptx Low latency 

To take advantage of the better performance of the APTX Low Latency Codec, the receiver must support the same codec. If the receiver only supports the normal AptX codec, or the SBC one, these codecs will be used instead.
