It’s miniature design also permits an ultra-compact construction which, thanks to the accompanying silicone and memory foam adapters, can be individually adjusted. This in-ear monitor is easy to handle and provides brilliant sound reproduction. Built to last under extreme stress, a secure and comfortable fit for hours.
