yup, it does. You can buy one in virtually any electronics store in HK (or I assume all the rest around Asia).

In fact, I own two...one purchased at an electronics store airside at HKIA, and another purchased airside at TPE. They are very cheap. The one I bought at TPE can connect 6 people at once! I have to imagine you can find these are SIN, BKK, or many other regional airports. I'm certain you can buy this at any electronics market in mainland China, etc.

Anyway, I've done this on more than one occasion. Seated in F with the Ms. it's nice to have the splitter so you can both watch at once.
