Luvfun TROND Bluetooth V4.2 Receiver Wireless 3.5mm Aux Adapter, AptX Low Latency, Volume Control & Smart Codec Indicator, for Wired Headphones or Speakers;

CD-Like Audio w/ AptX Low Latency
The latest CSR64215 chipset supports both aptX and aptX Low Latency. With aptX, you can enjoy CD-quality sound wirelessly over Bluetooth connections from aptX audio sources. With aptX LL, you can now watch video while listening to wireless audio in a synchronized fashion.

Smart Codec Indicator
Be smart, and don't let false advertising fool you. TROND BT-RX S can tell you which codec is in place, by displaying different LED status. After the music starts playing, its blue LED would blink once every 10 seconds for SBC, blink twice for aptX, and blink three times for aptX Low Latency.

Full Music Control
With the volume controller, you can remotely play/pause music, adjust volume up/down (quick press), and change track forward/backward (long press).

Applications:
- Connect to your wired earbuds or headphones, and turn them into wireless plus aptX LL;
