Koss UR10 on-ear headphones 3.5mm 4ft cord

On-ear design with 3.5 mm plug

The Koss UR10 is a lightweight on-ear headphone that connects through a standard 3.5 mm stereo jack. Its 32-ohm impedance and 94 dB sensitivity let it reach usable volume from phones, tablets and laptops without extra amplification. The straight, single-entry cord measures four feet and keeps the signal path simple. An adjustable headband provides a secure fit for listeners of any age.

Who benefits and who should look elsewhere

Commuters, students and office workers who want a compact wired headphone for music, calls or online classes will appreciate the low weight and deep bass response. The on-ear pads rest on the ears rather than sealing around them, so users who need strong isolation in noisy environments or who prefer over-ear comfort for marathon sessions should consider a different style. Wireless convenience and active noise cancellation are not offered by this model.

Deciding specification: 60 Hz to 20 kHz frequency

The published range of 60 Hz to 20 kHz determines whether the UR10 covers the tonal balance you expect from your favourite recordings. If your material relies on sub-bass extension below 60 Hz or you require ruler-flat response for critical monitoring, this headphone may not meet those needs. For general entertainment and everyday listening the stated bandwidth aligns with the deep-bass character highlighted by the manufacturer.
