Product Description


Our custom, ultra-wide balanced single armature driver is tuned to your liking and placed into a custom molded earphone for the ultimate in performance and comfort. Rather than spending upwards of $1,000 for custom earphones, we’ve taken our expertise and experience in creating these earphones at a fraction of the cost by doing it in-house, and not sacrificing the sound quality our customers have come to expect.

Need earphones for your guitar, your MP3 player, for traveling without dealing with screaming children, or for working out with earphones that will never fall out or feel uncomfortable, the Sleek Customs can be tailored to meet your audio needs. Speak with one of our representative and we’ll tune it specifically for you.

Decades of combined experience and over 10,000 custom hearing aids fitted has lead to the development of the Sleek Customs. Designed for optimum performance we take an extra step in determining what music our customers listen to, or what instruments they play and tune the earphone to meet their sonic needs.

Crisp treble, solid mids and deep, punchy bass tweaked to match your audio fingerprint for a completely custom earphone. Whether used for your guitar in a garage, or on stage, with your MP3 player on a plane, or in your room, the Sleek Customs deliver the ultimate in comfort and performance.



The CT6 is molded to fit to your ears and your ears only. 


The CT6's offer 30-32dB of Environmental Sound Control. More than double that of premium "noise cancelling" headphones.

  2. Best earphones I've ever owned 5 Star Review

    Posted by on 4th Dec 2015

    While reading the gear issue of Men's Journal some years ago I saw the SA 7 ear buds reviewed by the editors of the magazine. Intrigued by the outstanding review I went to the Sleek Audio website to learn more about them. It was while on the website that I saw the CT6 Customs. Appeared to be just what I was looking for. I've had the Bose earbuds and didn't really like the sound plus they wouldn't stay in my ears when I was working out. I have the Shure 310 earbuds and while I like the sound I was always looking for something a little better. Found them with the CT 6. Could not be happier. They live up to everything the company advertises. The sound is amazing, they are very comfortable to wear and they remain solidly in your ear canal while at the gym. I cannot emphasize this enough, the sound is incredible. I had them tuned for a plus bass and a plus treble. I also had them tuned to my preference of musical styles.

    After wearing them for several years I accidentally dropped one on a tile floor. I had dropped them before but not on a tile floor. Separated the shell from the top and also broke off a tiny little piece inside. I was crushed until I called Sleek Audio and talked to Mark. He told me he could fix it for their repair price of $50. He told me to send in both earbuds and he would polish them for me and send them back looking brand new. Sent them in and got them back exactly two weeks later. Perfect condition and sounding great once again. Extremely happy with the product and the customer service.
