I found an interesting device by Monster about a week ago. Apparently they make a headphone y splitter designed for Microsoft’s Zune. The design is somewhat in-line with the overall design of the current Zunes on the market. On the reverse side(not shown in the image) there are dual-volume controls to allow individual listening levels. I found that to be the only feature that made this device stand out from the rest. It feels solid in the hand, i can tell that they didn’t go cheap on the rubber around the cord. If you’r interested in picking this product up, consider getting it at Amazon as apposed to the Monster website as it’s a few dollars more there.

There are also other effects that have multiple signal outputs, such as the fact that when a person becomes their volume, the volume of others is likely to go down. Likewise, if three people are listening to a splitter, and another person connects to it, then the volume of the three is likely to do it down, and when one is disconnected from the splitter of the handset, the volume rises.
If you want to use a headphone splitter with more than two connections, then you should consider a splitter that also includes a signal amplifier. This increases the audio signal of the player and allows each listener to experience audio quality and clarity that is more like a single listener. You should consider a booster that also includes separate volume controls as this allows each listener to adjust the volume by itself if you wish. While a headphone splitter with a sound reinforcement is usually more expensive than a standard splitter, the benefits can certainly offset this cost. (view more if you like airpods)
