Isolator earphones are a great choice for today's active lifestyles. They tune out the world around you, so you can hear every detail in your music. These low-profile, in-ear earphones fit comfortably with hats and helmets. Ideal for commuting, travel and sports activities. MK5 high-output 6 mm neodymium moving coil drivers utilize a proprietary acoustic side branch and dampers to redistribute energy, smooth out response peaks and compensate for weak highs normally found in moving coil drivers. 35-42dB of noise isolation reduce the impulse to turn up the volume in order to drown out unwanted noise from the outside world. Quiet passages and soft dynamics come through clearly, and loud passages don't hammer your eardrums. Includes assorted eartips and carrying pouch.
