  • "Coolness Factor"
  • Build Quality
  • Comfort
  • Not Rated
    Noise Reduction
  • Sound Quality

Having used Bose earbuds previously, perhaps I've become a bit spoiled but, I couldn't afford them this time around. These earbuds are not a good subsitution. Sound quality is just ok, but technically poor for the money and they do not stay in your ear. I should have known better than to expect quality from KOSS.

Product Research


Overview: The Koss iL200 KTC in-ear headphones have a unique interlocking design for easy, tangle-free storage. An in-line remote/microphone lets you control your music and phone calls on your smartphone. These noise-isolating in-ear headphones block exterior noise so you can hear your music clearly, without outside interruption.

Interlocking Design: The iL200 KTCs interlocking design allows the earbuds to easily nestle together. This keeps the cables from getting tangled up while they are stored.

Construction: The in-ear headphone enclosures are constructed from a highly-polished machined metal, surrounded by a flexible, soft-touch material. The coating deadens external noise and vibrations, so all you hear is the music.

Koss Touch Control (KTC): The cable on the left earbud features the 3-button Koss Touch Control (KTC), an in-line remote control and microphone. The KTC is "made for iPhone, iPad, and iPod", and lets you control the volume, music playback, and phone call management.

Silicone Tips: The iL200 KTCs come with three sizes of silicone ear tips (small, medium, and large) for a comfortable fit.

Cord: The headphones have a 4' straight cord with a slender 3.5mm straight plug. The small diameter plug design can be easily plugged into recessed headphone jacks or when the smartphone or digital music player is contained in a hard case.

Warranty: The iL200 KTCs are covered by the Koss Stereophones Limited Lifetime Warranty.
