iPad Accessories: 2-into-1 Stereo Adapter

By Edward C. Baig, Bob LeVitus

If two people have only one iPad you can imagine the tug-of-war. No worries: A 2-into-1 stereo adapter is a handy little device that lets two people plug their headphones/earphones/headsets into one iPad (or iPod or iPhone for that matter). They’re quite inexpensive and extremely useful if you are traveling with a friend by air, sea, rail, or bus. They’re also great when you want to watch a movie with your BFF but don’t want to risk waking the neighbors or roommates.

Other names you might see for the same device are as follows:

  • 3.5mm stereo Y-splitter

  • 1/8-inch stereo 1-plug-to-2-jacks adapter

  • 1/8-inch stereo Y-adapter

  • 3.5mm dual stereo headphone jack splitter

  • And many others

You really only need to know two things. The first is that 1/8-inch and 3.5mm are used interchangeably in the adapter world (even though they’re not really the same).

Some measurements to keep in mind: 1/8 inch = 0.125 inch, whereas 3.5mm = 0.1378 inch. Not the same, but close enough for rock ’n’ roll.

The second is that you want to make sure that you get a stereo adapter. Some monaural adapters work but pump exactly the same sound into both ears, instead of sending the audio information for the left stereo channel to your left ear and the right stereo channel to your right.

In other words, you need a 1/8-inch or 3.5mm stereo adapter that has a single stereo plug on one end (to plug into your iPad) and two stereo jacks on the other (to accommodate two sets of headphones/earphones/headsets).

Test it before you travel. You may discover one person has it much louder than the other, or some other defect.
