Customer Feedback


“My wife & I have been traveling a lot and like to watch stuff on our iPad together. We ordered this product and used the splitter so we both could use our noise cancelling headphones and watch the same program on the flight. It worked perfectly — the sound was loud in both of our earphones and it didn’t diminish any sound quality we could notice. If you want a great headphone splitter, this is it — don’t look further. You’ll be happy with this.”


“Hello everyone God Bless I do livestream for my clients the sound of my videos was Eh ok But I need it to take this to another level so I have this crazy idea with my zoom h5 and this is the results love it totally recommend this product worth every pennie love it built quality is crazy its amazing”


“Works great- no static just clean sound.. I was a little suspect given the really small gauge of the wire but the connectors and wire carry nice clear sound. I have had great success with other STC cables and this one is no exception. My primary use for this splitter is to link two ION Block Rocker Max Bluetooth Speakers and it works great. It gives me portable stereo sound that packs a punch.”


“This is a great splitter. I plug it in the front of my stereo receiver with an adapter plug. From there I have two sets of earbuds plugged in to the ports of the splitter. I have another Egreen adapter cord that goes from the tv to the back of the stereo to allow TV sound on the old receiver. The sound is excellent. Works great for my old receiver, 2016 smart TV and cell phone ear buds.”
