This whole product seems like a scamThe instructions are so-so. There are two websites listed for tech support, depending on which brand the product is. I looked all over the actual product, the box, and the Amazon description and could not find any brand name at all. But, it doesn't matter as neither of the websites is functional.I did try actually using the product. It turned on. I put it in transmission mode. The display cycled between searching and pairing, but it never actually paired with my headphones. I tried starting the process about 8 times with no luck.I give up. I'm returning it.0
