There is no built-in Bluetooth or WiFi technology in the headphones. But if you have an iPod shuffle 4G, ODDIO1 cord-free headphones will bring you beautiful music in a wireless way.
ODDIO1 is a pair of unique cord-free headphones dedicatedly designed for Apple iPod shuffle 4G, by designers Jeremy Saxton and Jacob Hall. The wireless headphones consist of two parts, including a nylon plastic, outer chassis and an inner cushion made of high-grade silicone. As we can see from the images, the headphones feature an integrated housing, so you can easily slide your iPod shuffle 4G into it, and connect the music player with the headphones via the integrated 3.5m audio connector, while the 30mm dynamic audio drivers will deliver you nice sound. In addition, the headband is fully adjustable.
ODDIO1 cord-free headphones are available in four colorways, including grey/black, black/blue, black/pink and limited edition Cupertino. At present, the designers of ODDIO1 is raising fund on Kickstarter. Pledge $35 will let you own the cord-free headphones. If you’re interested, jump to Kickstarter for more details.
