BLUETOOTH TRANSMITTER AND RECEIVER: Transmitter function transforms 3.5mm audio-out media devices into a Bluetooth device capable of streaming Bluetooth audio; Receiver lets non-Bluetooth devices like car or home stereos receive high quality audio. INSTANT SOUND: Enjoy a latency lower than 95% of other devices with aptX Low Latency technology; end-to-end lag time is now 40 milliseconds so high-definition video is transmitted without problems in Transmitter mode. A 2 FOR 1 CONNECTION: Two Bluetooth headphones or speakers can pair at once so children can watch in silence and give parents a needed break. Note: aptX Low Latency does NOT support Dual Pair mode.
