‘split’ by miami-based greenwingaudio is a standalone, hands-free music player that unobtrusively fits in your ears, working without cables and bluetooth. the penny-sized audio system contains a small circuit board, button cell battery, 256mb memory chip and a 32 bit ARM cortex m3 processor for a high-quality and tangle-free listening experience. by synchronizing the right and left earphone with two high-precision crystal clocks, the pair of 6mm neodymium dynamic drivers play in unison without being physically connected or exchanging a continuous stream of radio waves.


to change the track and volume, users simply bite down with their jaw, where a vibration signal is detected by a custom-made three-axis accelerometer. compatible with both windows and iOS operating systems, ‘split’ connects to the standard USB port of your computer with outlets for two different specially designed cables: one for uploading songs and one for recharging the batteries. to learn more about the wireless headphones, check out the project on kickstarter here, as it is currently seeking funding.

  • These headphones are off to a good start, but nobody will buy them unless essential features are improved. 24 songs won’t get you anywhere, so they absolutely will first need a larger flash memory. At least 2GB like the iPod Shuffle. And a Bluetooth connection wouldn’t be all that bad, especially since so much headphone use is from the computer. What happens if one or both of the pods are misplaced? Can there be a signal synced to your smart phone to alert where they are located? Or maybe an alarm to find them? It would be nearly impossible to pack large batteries in such a small product, so maybe they could have ports for an optional mini audio jack cable. I would definitely be purchasing these if they met some of the important requirements that revolutionary headphones need. Let me know what you think! Thanks!

  • They’ll make a lot of money, folks will be losing them EVERYDAY… Not practical at all.

  • There is a lock feature on the earbuds that allow you to chew freely without skipping any songs.

  • Using the market’s most efficient memory and battery pieces for its size, the headphones can hold about 24 songs. Is the convenience of no wires worth the limit this imposes on the quantity of songs it can hold.

  • It will be fun when you eat your sandwich in the morning, you probably skip a couple of times through all your songs, or get a nice mash-up

  • As an electroacoustic engineer I call B.S. Yet another Kickstarter pie in the sky fraud.

  • Gorgeous, well thought out and executed.
