Koss KSC32IV FitClips earbud accessory violet 15-20KHz 16 ohms 104dB 3.5mm 4ft

Violet FitClips for active listeners

The KSC32IV earbuds combine a violet finish with flexible ear clips that stay in place during workouts or daily commutes. Sweat-resistant coating protects the drivers from moisture, while the 3.5 mm plug connects directly to phones, tablets or laptops. An in-line one-touch microphone handles calls and basic playback control without reaching for the device. Lightweight construction keeps fatigue low over long sessions.

Simple plug-and-play setup

Insert the 3.5 mm connector into any standard headphone jack and the buds are ready; no drivers, pairing or software are required. The soft clips adjust by bending gently until they hook securely around each ear — forcing them can snap the flexible arms. Cord length is four feet, so routing it under a shirt prevents snagging on equipment. If the microphone stops responding, check the inline housing for lint or moisture before assuming a fault.

15 Hz – 20 kHz range with 104 dB sensitivity

The 16 ohm impedance lets portable sources drive the buds to loud volumes without extra amplification. Bass extends down to 15 Hz for electronic and hip-hop tracks, while the 20 kHz ceiling preserves treble detail in acoustic material. At very high output levels the small drivers can compress, and the open ported design leaks sound in quiet rooms. For critical mixing or noise isolation, over-ear alternatives are more suitable.
