Urbanears - Medis is an unprecedented experience in ergonomics and functionality. The patented EarClick solution secures the earpiece at two separate points rather than one, relieving pressure to a nearly non-existent level while keeping it firmly in place. Additionally, the Medis rests a small distance from your ear canal and therefore doesn"t affect your balance. Naturally the Medis features a dynamic sound and the sleek and minimal design that is synonymous with Urbanears.
