It would be easy for people to keep track of one another if they're searching for something over a large area such as a missing person. A more comfortable example would be two men at a warehouse searching for a product.
Two way radio headsets can be purchased at a variety of retailers. Some of the online retailers include eBay, Amazon, Rugged Radios, Walmart, and Radio Shack.
Most headsets now have a volume control built in, however I've only ever come across two USB headsets.
yes you can
I'm looking for 2 additional headsets. I found some on ebay. Around $45 for two.
Yes you can, but it is kind of tricky. First, buy a USB to 3.5mm adapter. Next, buy two 3.5mm "Y" adapters (one for the mic and one for the audio). Last, buy two 3.5mm wired headsets and connect them all together. This will allow two players to chat with other on-line players at the same time. This does not work for game sounds or audio from other media like movies, only for chat. Unfortunately, this does not work for USB headsets or Bluetooth headsets.
Motorola (headsets) and Reebok (Jerseys)
Stereo headsets would primarily be used for listening to music. With a stereo headset there would be two different sounds of the same track coming in through both earpieces.
