How to get the best performance:

• Please use 2×AAA premium alkaline batteries and make sure they are inserted properly.
• Please check that the volume on your DVD player (and on the headphones), make sure they are turned up at a sufficient level.
• Please make sure that you try both channels on the headphones as your vehicle may be transmitting on either channel A or B. Using the wrong channel will cause intermittent sound issues.
• If your kids watch different movies on two DVDs, set each DVD on a different channel, and the headphone to the channel of the DVD you would like to listen to. Make sure your kids sit more than 20 inches apart to avoid the interference.
• If you installed a ceiling/roof mounted DVD player for all the people in different rows to watch the same program, we suggest you to choose channel A for both your DVD and headphone which may have better performance than channel B.
• For the toddler or someone who feel the headphone is too big, we suggest to use the included adjustable headbands to fit you better. The headband incorporates memory elastic stainless steel strips inside, you can remould the headband shape to fit you better, or adjust the wearing angle to make the headphones fit snug on your ears.
