Audiofly's Detachable Bluetooth Headphone Cable
This cable features a built-in Bluetooth receiver, battery and microphone. It transforms your awesome sounding in-ear headphones into the most convenient pair of headphones around. Then when you want to listen critically (or you've run out of battery) you can just plug your old cable right back in!
The Bluetooth receiver is perfectly compatible with the latest iOS devices, so is perfect for devices with no 3.5mm output...
Thanks Audiofly, another great addition to the range.
