KOSS The Plug Wired Earbuds

The KOSS The Plug 156407 are wired in-ear headphones with a 3.5mm connector and memory foam cushions in two sizes. They deliver a frequency response of 10 to 23000 Hz and a sensitivity of 103 decibels at 16 ohms impedance. The four-foot cord connects directly to phones, tablets and laptops without a battery.

Listeners wanting passive isolation and bass

These suit commuters and office workers who want ambient noise reduced by foam tips that mold to the ear canal. The single-ear coupling and wired design mean they are not for users who need true wireless freedom, active noise cancellation or a built-in microphone for calls.

10 to 23000 Hz range with 103 dB sensitivity

The dynamic elements and acoustical vents handle deep bass and crisp highs comfortably at portable device volumes. At 16 ohms they run loud from a phone output without an amplifier. The 3.5mm plug limits use to devices with a headphone jack; there is no USB-C or Lightning option.

Questions about this item

Does my device need a 3.5 mm headphone jack to use these wired earbuds?

Yes, the 3.5 mm connector plugs directly into any standard headphone jack; no adapter or power source is required.

Will the 16 ohm impedance and 103 dB sensitivity work well with an older portable player?

The low 16 ohm impedance and high 103 dB sensitivity make them easy to drive, so older players can reach loud volume without strain.

How can I confirm the earbuds are reproducing the full 10 Hz to 23,000 Hz range after I put them in?

Play a frequency sweep track; you should hear audible output from the deepest bass up to the highest treble without roll-off.
