Doesn't work

I purchased this in August to use for my earphones at the school I work at. I have not had the opportunity to use them until now. It does not work with my apple iphone or ipad to listen to my webinars. There is an error that it is not compatible with my product. Useless and a waste of money. I just clicked on the description from I purchased it and they are no longer available and have a one star. Buyer beware. I did not notify the seller as I purchased it almost 3 months ago and figured they wouldn't replace them anyway.
