Featuring a black soft-feel paint finish with off-white lettering on its earbuds, Custom-1 earphones utilize dark gray patent-pending Contour Ear Gels that are anatomically designed to accurately fit inside the human ear canal. These soft, oval silicon tips reduce ear fatigue as well as provide an amazing seal for excellent noise isolation and bass response.

Because ear canal measurements vary, Custom-1 comes with five different washable ear gel sizes: small, medium, and large single flange designs as well as small and large double flange designs. Extra small sizes can be ordered via the klipsch.com web store. Such variety allows these earphones to fit more of the population than the competition.

For perfect exterior comfort, flexible ear wires bend over and around the ears so they can be customized to each user. It may take you a few minutes to find the perfect fit, but once you get it right, the time will be well worth it. And not only do these adaptable wires provide optimal comfort, they also let users experience full or partial noise isolation—a great safety feature for on-the-go users. Just pull the ear gels out of the ear canals and adjust the wires to firmly position the earphone nozzles over the canals.

Wherever you go, Custom-1 lets stunningly precise audio go with you. Exclusive KG332 balanced armatures generate deeper bass, a more robust midrange, and clearer high notes for that true-to-life listening experience only Klipsch can deliver. And if you find yourself not completely blown away by Custom-1’s performance, you probably don’t have the right fit or seal. So be sure to try out various ear tip sizes.

Klipsch has gone to great lengths to ensure the long-lasting durability of Custom-1 earphones, up to and including its 50-inch-long cables. Put through extensive “real world” testing, these headphones feature appropriate strain relief at every cable connection point to help prevent wire damage. Plus, underneath the cable’s black cloth weaving, a special PVC Wireguard jacket prevents the wires from becoming exposed and frayed.

Great iPod headphones, Custom-1 also works with the iPhone and virtually any device with a headphone jack. These headphones come with a compact high-quality vinyl carrying case, five sets of ear gels, and an ear tip cleaning tool.
