I emailed the seller about this and they said that it was unusual that the product didn't work

Don't buy this if you intend to use it for audio purposes

Two have broken already with daily use - and they were not abused, just connected to 30 pin audio players sitting in fixed locations

It does not allow me to play music from my Iphone 6 and Iphone 4 docking station

0 out of 4 supported audio

I was glad to get the refund, but I believe they know this is a crappy product that doesn't work and that is why they refused to send me replacements (because they knew those wouldn't work either)
