We discovered these a few weeks back looking for headphone splitters for a classroom set of laptops. We needed them for group work on media editing avoiding drowning out the whole room with tinny laptop sounds. Most splitters cater for 2 headsets but we needed more for groups of 3 or 4.
It’s called the Rockstar by Belkin and it’s really an iPod accessory but works fine with computers. We got them for around £6 each from a regular business IT supplier.
Nothing revolutionary but though it might be useful for someone.
