The Link: Turn Any Speaker a Wireless iPhone Speaker0
So you have old speakers that do not have Bluetooth or NFC technology on-board? You don’t have to get rid of them necessarily. The Link happens to be a handy device that converts any wired speaker into a wireless Bluetooth speaker. The device is small and portable. It is also rechargeable. Just connect it to your speaker system, and you are set.
The Link offers up to 25 hours of battery life. It is made of recyclable components and has a working range of 50 feet. It is small enough to fit on your keychain and looks pretty decent. Like what you see? Support this project on Kickstarter.
