Witness the magic of the Jack adapter.
If you're not quite prepared to spend your hard-earned cash on a pair of wireless earbuds that are destined to get lost in the crevices of your couch, there's a new option for listening to music untethered. With Jack, any pair of headphones or speakers can become "wireless" instantly—all you have to do is plug the aux cord into the Jack adapter, turn on your device's Bluetooth capabilities, and you're good to go.
The rechargeable device makes it easy to listen to music or podcasts with added mobility. Jack can be clipped onto your clothing for security, and it can even sync with a friend's phone, so you don't have to hunch over your speaker to share your new favorite song.
Jack can also easily switch between devices, so you can flip from Netflix on your laptop to music on your phone to video games on the TV in an instant. You with the short attention span—yeah, this gadget's for you.
