Koss KE5K (175481) earbud accessory 3.5mm 4ft 60Hz-20KHz 32 ohms 0.1 black

On-the-go earbuds for daily listening

The Koss KE5K earbuds are built for people who want a lightweight, wired option they can carry anywhere. A straight, dual-entry cord runs four feet and ends in a 3.5 mm plug that fits phones, laptops and portable players. The earbud coupling sits in the ear for a secure fit during walks, commutes or desk work.

Wired 3.5 mm connection limits

The 3.5 mm jack restricts use to devices that still provide an analogue headphone socket or a compatible adapter. With a 32 ohm impedance the earbuds draw modest power, so output volume will depend on the source device’s headphone amplifier. The four-foot cord length sets a fixed working radius and cannot be extended without an extra cable.

Replaces basic bundled earbuds

These earbuds step up from the thin, single-driver buds often packed with a phone or player, offering a wider 60 Hz to 20 kHz frequency range and a more durable straight cord. The upgrade is worth it when you want clearer bass and treble without moving to a premium in-ear monitor or wireless set. Buyers who need active noise cancellation, a detachable cable or a balanced connector will not find those features here.
