Highly-Detailed, Immersive Sound Profile:-

The new Klean SV utilizes the latest DLC material(Diamond-Like Carbon) diaphragm. DLC is one of the hardest and lightest materials in the world with high mechanical strength. Kefine has adjusted the tuning of the Klean SV for a clean and detailed sound presentation. It focuses on delivering fast transients with next-level resolution and clarity. Kefine Klean SV provides wide extensions in both Treble as well as bass sections.

Highly-Consistent Sound with Dual-Cavity Dynamic Driver:-

Polishing is done for a clean and premium finish. The front and rear cavities are joined together using a screw for a consistent finish.

Very good product
Size: Medium, Color: (001) Black / Black / Pitch Gray
I purchased these to wear inside lowcut slip on casual shoes, I don't particularly like to not wear socks in my shoes for hygienic reasons. Prior to purchasing these socks, all I could find were those made of very light beige hosiery type material , and my slip on shoes would slide around a bit. These are light weight and breathable athletic type material, with a very good gripper strip at the heel. One pair of my slip on casual shoes have a particularly lower cut in the toe area, but the shoe is black and I chose the black color and though I see a hint of the sock there, it matches and does not detract from the look of the casual solid black shoe

They stay out! No more sock wads!
Size: Medium, Color: (100) White / White / Mod Gray
Best no show socks ever made!!!!! I've been struggling for 2 years to find ones that actually stay on your foot, even other national brands, and I just became content wearing my sneakers without socks. They ALWAYS slid down into my show & I ended up walking on a wad of sock until I could fix it...or usually just took them off after a couple of tries. Enter Under Armor!!! They a mid weight, but not very thick & still breathable. They work too by actually staying on your foot! Not once have they slid down into my show!! Very comfortable but they could be a little more affordable.
