What this headphone is

The Koss KPH7 is an on-ear stereo headphone with a 3.5 mm connector and a 4.00 ft cord. It is built for listeners who want ultra-light headphones for portable MP3 players or iPods. The adjustable headband gives a secure fit for any age. Buyers who need wireless operation or active noise cancellation should look elsewhere.

Thermals noise and power

Passive headphones generate no heat and draw no power from the source device. The 32 ohm impedance and 91 dB sensitivity allow adequate volume from portable players without an external amplifier. There is no fan or active circuitry to create audible noise. The foam earpads provide passive isolation only.

The spec that decides fit

Frequency response runs from 80 Hz to 18,000 Hz, delivering deep bass and extended treble for the Sound of Koss signature. The 3.5 mm mini-phone plug connects directly to standard headphone jacks on portable devices. If your source lacks a 3.5 mm jack or you require a detachable cable, this model will not suit.

Questions about this item

How do I install the KPH7 headphones, and what step do people often miss?

Plug the 3.5 mm connector into the device jack until it clicks; the straight dual-entry 4.00 ft cord must not be twisted at the Y-split or one earcup will lose signal.

What maintenance or replacement will the KPH7 need later?

The foam ear cushions compress over time; replace them when they no longer seal against the ear or the adjustable headband tension drops.

What limit appears first during sustained high-volume use?

The 91 dB sensitivity at 32 ohms means the dynamic elements reach maximum clean output quickly; prolonged peaks at that level will produce audible distortion.
