Question: Could I use it to connect 2 audio/music devices and one pair of headphones
Document: Before getting this, I had one pair of headphones for my phone and another for my laptop. This allowed me to plug my headphones into both devices at the same time.
Worked perfectly but I use them so I can listen to both my ipods at the same time I use one for either binaural tone or audio books and the other one for background music. I've been training a lot lately and the wiring went bad like cheap headphones. If your using it for a stationary thing I recommend this its definitely stereo unlike the reviews on some of the other ones. If your moving definitely want to find better quality.
Why is there never the ability to give ZERO stars?I was planning to use this 'thing' to plug one pair of ear buds into my ipad and mac at the same time. It works, somewhat, however one side when plugged into an audio source creates a kind of annoying buzz. I contacted the company and received prompt and friendly service promising to get a replacement to me, from two separate company reps...but 2-3 weeks later they have gone quiet on me.
Perfect in all respects. I can connect two devices to my headphones and each works in stereo as they do when not using this splitter. At the gym my headphones are now connected to both my Sony Walkman radio and my Sandisk Zip clip MP3 player at the same time and I can listen to either one or the other, or both at the same time.
I bought this as a cheap way to try and connect to two audio inputs with a single headset. It works, but I get a real strange feedback/beeping. My two sources are 1 my PC, 2 my deskphone. works create when I use it with my deskphone and another device, but when I plug it into my  PC it buzzes terribly if the other is plugged into anything. Bottom line is, if you want something cheap that will work, this will do it.
I have an audio output from my bluetooth receiver(connected to my phone and laptop) and another audio output from my desktop but only one set of speakers at my work place. So I used to connect both the audio inputs to the speaker. Works perfectly. For 2.4$ and free shipping and a decent quality, I cannot ask for more.
This product is only a cable - the user should have some knowledge of what he is trying to do with it. You should not connect two outputs together to drive one input(as this cable allows you to do). Doing so could damage one or both of the output drivers and will certainly result in less-than-optimal sound. It is not the fault of the cable. If you want to mix audio signals, buy an audio mixer.
I needed to run two inputs to a set of computer speakers - my computer and an airport express so I could beam music from my phone and still use said computer. For this scenario it worked perfectly.
Perfect for what I needed!!! I wanted to use headphones on my keyboard while listening to the song I was playing on my iPod. Working wonderfully. Now I can learn the music and not disturb my family.
I have an EOS M which has a Mic input. I don't have a mic but do have a H4n. I mount my H4n on top, connect the output of that to my camera's input using this cable and the cable's output to my headphones. Now I can listen to the audio as it records both to my M and H4n, so syncing's better later on. Great product!
Answer: Sure, I bought this to connect both my Xbox and my PC to the same set of speakers.
