It is hard to work out, but these incredible little speakers are only the size of a matchbox, which is about 2.5 inches x 1.5 inches and yet they offer fantastic sound transfer between the laptop, TV, speakers and headphones.
Features – The devices enable you to listen to TV in bed without disturbing a spouse, or to roam freely while wearing headphones without being tethered to an MP3 player or stereo. CD-quality audio is transmitted up to 30′ over the 2.4GHz band for interference-free listening. Each transmitter plugs into a USB port for charging and works for seven hour
