Kindly reminder

1. If it’s the first time for you to use our universal IR headphones and experience no sound, audio cuts, only hear sound by one side, most are caused by car DVD’s frequencies deviation (non-universal). Please check IR sensor  frequencies of your car DVD player and make sure they are compatible with these headphones (Channel A: L/2.3MHZ, R/2.8MHZ; Channel B: L/3.2MHZ,R/3.8MHZ), or you will need to return these headphones and purchase the  original ones.
2. set the volume of car DVD/TV and TV related AV devices (e.g., cable box, STB, DirecTV etc) to a sufficient level to ensure steady audio signal, or sound will be cut out.
3. If your car DVDs are universal, then please pay attention to the IR transmitting angle and distance. Sound will be cracking if too far away, or not in sight of IR transmitter, which is caused by the limitation of the IR system type, not  the product itself.
4. Some DVD manufacturers ignore the quality of built-in infrared transmitter. The poor IR transmitting modules as well as the mounting angle and quantity of infrared-ray emission tube, all of these will cause poor audio reception.
5. Please use 2XAAA decent and premium alkaline batteries. Not suggest to use rechargeable NI-MH battery. The headphone working voltage is 3.0V, the premium alkaline battery life could be at least 20 hours. But for some bad quality battery, the capacity is much less than the premium one, the using time is much shorter than expectation. For rechargeable 2XAAA NI MH batteries, the voltage is only 2.4V which will cause low volume, poor sound quality or sound cuts in and out etc. It will be reduced to 2.2V after about an hour using, and the headphones will stop working.
