What if it were possible to listen to music on a personal gadget without the hassle of earbud wires getting tangled or kinked? With Earin, that idea is a reality. The two earbuds function as Bluetooth headphones that feature balanced armature speakers. These are the same type of speakers used in professional in-ear monitors and hearing-aides, so the best sound experience is offered without a great deal of power consumption. The wireless earbuds are rechargeable when stored in their capsule. For £79, early bird backers get one set with an expected delivery of January 2015. The earbuds are expected to retail for £159.
