Important Notes

1. Walls and metal barriers will shorten Bluetooth transmission distance. Keep clear line of sight between devices for stable connection.
2. aptX-LL low latency requires both transmitter and headphones to support this codec; audio will automatically switch to other codecs if unsupported.
3. Charge regularly if not in long-term use to protect lithium battery. Avoid high temperature and humid storage environment.
4. Minor dimensional tolerance exists due to manual measurement. Product color may vary slightly on different monitors, please refer to real item.
