Review of Sleek Audio CT6 Customs on Slashgear
June 11, 2009
“For your money you’re getting not only custom molded earphones, as a fair few other companies offer, but custom tuning too. It’s the latter that would see us picking Sleek Audio over the other premium headphones offered”

“You might think comparing the SA6s to a reference quality loudspeaker is a bit unfair or is designed to point out their shortcomings but that isn’t the point. The point is to determine where they fall on the scale between poor quality and reference quality sound. And the fact that they performed so well is a testament to the engineering and concern for sound quality that went into these earphones.” – Adam Goldfine, Positive Feedback Online, Issue 37

Review of Sleek Audio Custom Earphones
Sleek-Audio made a remarkable entry into the world of in-ears almost a year ago with the successful launch of their SA6 customizable earphones. Today I have the pleasure of putting their first custom earphones through its paces. Based upon the same principles as the SA6 the user decides the frequency response. However, unlike the SA6 you cannot change the sound signature after they are produced. In the ordering process you decided what level of bass and treble you want. Since they are custom in-ears you also get to choose the color and graphics if you want that.

Sleek Audio W-1 Kleer wireless headphones system Review
“Sound quality is pretty much indistinguishable from a wired connection in most scenarios. Kleer supports wireless frequencies between 20Hz and 20KHz with less than 0.1-percent distortion; in practical terms, all the uncompressed and 320kbps tracks that sounded so fantastic with the wired SA6’s sounded just as full bodied and clear with the wireless.”

Review: SLEEK AUDIO SA6 In-Ear Headphones
Sing To Your Ears
By Danny Dumas February 21, 2008 | 12:01:00 PMCategories: Audio, Reviews Eschewing the one-sound-fits-all headphone paradigm, personal audio newcomer Sleek Audio sets the mark for sound customization and modular design. Created by Mark Krywko, a 30-year veteran of hearing aid design, these mini-concert halls are built around a tiny super wide band single armature driver with interchangeable treble tips and bass ports and sport a detachable cord. Straight out of the box the SA6’s delivered luscious fidelity. But why stop there?

“Slot in the plus tubes, however, and it was a revelation; thick, satisfying bass which manages both clarity – in reproducing the individual beats and doing so quickly – and texture.”

Sleek-Audio is a new company that makes some very unique earphones. The earphones are dubbed SA6 and feature a lot of highly innovative features such as tuning ports that allow the user to customize the sound signature of the earphones. Even though Sleek-Audio is a relatively new brand they have already developed a good name for themselves. Their dedication and support for the product and excellent customer reviews have most definitely helped to promote the brand and further added to the hype about the Sleek-Audio earphones.

“Sleek Audio stormed the high-end personal audio market with their SA6 in-ear monitor earphones, and now the company is preparing to cut the cord with their imminent Kleer wireless adapter. In an exclusive interview with Mark and Jason Krywko, the father & son team behind Sleek Audio, we discussed the upcoming launch, why Bluetooth just isn’t good enough, and some as-yet-unannounced products.”
Review on Hifi Headphones, Sleek Audio SA6 vs Klipsch X10
September 8, 2008
“While the Klipsch Image X10 sounds great when you first try them out, the SA6 is the definite winner when you listen for extended periods. The recessed mid trebles of the Klipsch Image X10 become really frustrating when listening to female vocals and acoustic guitar. I love the energetic delivery of the Sleek Audio SA6.”
