Koss UR29 full-size headphones

The Koss UR29 full-size headphones deliver bass-enhanced sound with dynamic elements built from 1.4mm Mylar. Closed leatherette ear cushions provide isolation while the padded adjustable headband supports extended listening sessions. Frequency response spans 18Hz to 20kHz with 100ohm impedance and 101dB/mW sensitivity.

Setup and common issues

Connect the 8ft straight single-entry cord via the gold-flashed 3.5mm plug or the included gold-flashed 1/4 inch adapter. Volume control on the cord allows quick level adjustments without reaching for the source device. Ear cups rotate and fold inward to collapse into a protective package for storage or transport.

Before you order

Verify your device offers a 3.5mm or 1/4 inch headphone output compatible with the supplied plugs. The 100ohm impedance works well with portable players and home equipment but may require more drive voltage than low-impedance models. Ensure you have space for the full-size frame and the 8ft cable length in your intended use scenario.

Questions about this item

How can I verify the UR29 headphones are performing correctly after connecting them?

Listen for bass-enhanced sound across the 18Hz-20kHz range and use the in-line volume control to adjust levels smoothly without distortion.

What accessories come with the Koss 178295 and what must I purchase separately?

The box includes the headphones with 8ft cord, gold-flashed 3.5mm plug, and gold-flashed 1/4" adapter; no extra items are required for standard audio sources.

Which impedance version of the UR29 should I choose for my device?

This model has a fixed 100ohm impedance and 101dB/mW sensitivity, so there is no alternative version to select.
