Headphone newcomer Sleek Audio has introduced a new twist on high-end earphones. Their debut product, the SA6 in-ear headphones ($249) are the first set of earphones we've seen that allow you to customize treble and bass responsiveness by swapping interchangeable parts.
The Sleek Audio SA6 earphones are lightweight and attractive, with a black-and-chrome aesthetic. Each set of SA6 earphones comes with a selection of three sizes of flanged silicone ear fittings and a detachable 4-foot cable that terminates in a gold-plated 3.5mm jack. Also included is a plastic clamshell case for storing the SA6 earphones, which we found to be more attractive than functional.
If the Sleek Audio SA6 earphones have a claim to fame, it's their modular approach to tuning the treble and bass response to your taste. While the Sleek Audio SA6 earphones work great right out of the box, three pairs of interchangeable Treble Tips and Bass Ports are included with the package, allowing you to increase or decrease the perceived amount of low end or high end for each ear. Be warned, you do have to be fairly nimble-fingered to swap out these tiny parts, but once you've configured your perfect recipe for audio bliss, you probably won't need to revisit the tiny parts again.
Another distinguishing feature found on the Sleek Audio SA6 earphones is their detachable cable design. The included headphone cable connects to the SA6 earpieces using a miniature, gold-plated coaxial jack found in the back or the earpiece. This detachable cable design not only makes it easy to replace broken cables, but the use of a rotatable coaxial connection makes it easier to position the cable around the ear. The downside to all these detachable parts, of course, is that there's approximately nine little parts to lose at any given moment.
