Portable On-Ear Headset

The Koss UR10I is a lightweight on-ear headphone with an in-line push-to-talk microphone. It connects through a standard 3.5mm plug for simple compatibility with phones and laptops. The adjustable headband fits a range of head sizes for daily commuting or office calls. Weighing only 0.25 lb, it adds minimal bulk to a bag.

Adjustable Build and Wired Connection

A durable over-the-head frame uses an adjustable band to secure the earcups without clamping pressure. The single-entry 4.00 ft cord terminates in a straight 3.5mm mini-phone connector that plugs directly into a device. No battery or pairing is required, so the headset works immediately on any host with a headphone jack. The in-line microphone cable keeps call controls at chest level.

Passive Operation and Efficient Drivers

With 32 ohm impedance and 94dB sensitivity at 1kHz, the drivers reach adequate volume from low-power outputs without an amplifier. The 60Hz to 20000Hz frequency response covers the full audible range for music and voice. Passive on-ear cups provide some isolation while allowing ambient awareness. Zero power draw means unlimited talk and listen time.

Questions about this item

What does the 3.5 mm connector support for audio and mic signals?

The 3.5 mm plug carries stereo audio and the in-line push-to-talk microphone on a single four-foot cable, compatible with most phones that provide a 3.5 mm audio jack.

What physical space and weight should I expect for the on-ear fit?

The headphones weigh 0.25 lb and use an over-the-head design with an adjustable headband that fits a wide range of head sizes.

How do I set up the in-line push-to-talk microphone for calls?

Plug the 3.5 mm connector into the device jack, then press the in-line button to answer or end calls; the mic is passive and needs no separate power or driver.
