Works well

I got my nephew gaming headphones which required one of this Y splitters. Originally wanted to get from ebay for half price but didn't want to have my nephew wait weeks to receive it from China. With Amazon prime it arrived in 2 days and it worked well with his headphones. I guses money well spent then lol
