Over the years, inner ear monitors have become far more comfortable than their intrusive forebears. Although progress has been made, there is always room for improvement, especially for something so frequently used. A fully customizable set of IEMs molded to your individual ear shape, the Sleek Audio CT7 Custom IEMs give you the exact pair of earphones you've always wanted with a custom sound available only from Sleek Audio.

Optimize With Options

After visiting an audiologist to get ear impressions made, we'll introduce you to Jason at Sleek Audio and the two of you will go over all the custom options available. In addition to a unique shape, you can choose various options such as bass tuning, treble tuning, canal length, color, and graphics (graphics impact the price so we've made a checkout options so you can have one complete transaction). No matter what combo you go with, the CT7 puts out crisp treble, solid mids, and deep bass for an all-around excellent audio range. What’s more, Sleek Audio slipped in 30 - 32 dB of environmental sound control, giving you more than double the isolation of most noise canceling headphones.

Sleeks Own Drivers

Most high-end IEMs are using three or more balanced armature drivers per side. The Sleek CT7, is using two. Here's what most people don't know about BA drivers though; they're all made by one of two manufacturing companies and nearly every CIEM company is using the same generic designs as everyone else. Sleek Audio took a different approach, investing significant time and money into the development of their own Ultra-Wide Band balanced armature drivers, and hiring one of the two best manufacturers to produce it. The result is a more dramatic, detailed, and full frequency response from two custom armatures than you get with anything using up to eight generic drivers per side. The CT7s on Massdrop, represent the best sound quality per dollar available in CIEMs right now.
