Blinx and you will miss it!

Blinx are a very high quality pair of earphones, but more importantly they come fitted with 3 micro LED's in each earphone which are sound responsive! They pulse in tune to your favourite music . The LED's are volume sensitive and pulse more intenseley as the volume is increased.

Blinx headphones work with any device with a standard 3.5mm headphone jack. When the earphones are switched on and plugged into any sound source (MP3, CD Player or Cassette Player) the LED's flash in time to the music, giving a fantastic light show when viewed in low light. Foam ear bud protectors, instruction leaflet and batteries are all included.
