The Belkin headphone splitter adapter is a great accessory to have on hand for long trips or nights at the coffee house. Its purpose is simple. It allows two people to plug their own headphones into the same device. This is great for a long flight where you and another person may want to watch the same movie on an iPad or iPhone.

Headphone splitters are a relatively cheap way to share media with someone else from one device. I've always found headphone splitters extremely useful on long car rides or flights. Two people can watch the same movie or listen to the same music off one device. This was always great when I was traveling with a friend who didn't have an iPad or iPhone.

Overall, I didn't notice any sound quality reduction from using the splitter with the iPad or iPhone. I tried with just regular headphones and then with 2 pairs of headphones plugged into the splitter. This is an extremely cheap accessory that's easy to place in a travel bag and forget about. It's there when you need it. They are available in both black and white.

You can pick one up from the Belkin headphone splitter adapter from the TiPb accessory store for $4.95 right now (that's 75% off).

Pros

Easy to use and connect
Small so it's easily stowed away in any bag or purse
Standard headphone jack size allows for virtually any headphones to be used

Cons

If you use an Apple bumper on your iPhone 4, the adapter won't fit. You'll have to remove the bumper
As the main connection is somewhat wide, you may have issues fitting it in the headphone jack with certain cases.
