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. 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. Due to Bluetooth technology limitation, aptX Low Latency codec does NOT support under dual link. Audio delay when paired with different headphones/receiver‐ Headphones/receiver support ‐ The audio delay will be aptX Low Latency codec Around 40ms
aptX codec Around 180ms
