Verdict

The Koss UR20 are budget-friendly, closed-back over-ear headphones designed for home studio monitoring, DJ use, and casual listening, featuring 32 Ohm impedance, 30-20,000 Hz frequency response, and an extra-long 2.4-meter (8-foot) straight cable. Their main characteristics include large, comfortable leatherette ear cushions for passive noise isolation and a lightweight, highly flexible, self-adjusting headband, making them durable enough for daily use. Pros include excellent value for money, deep bass response, and a comfortable, secure fit even for glasses wearers. Main cons are a lack of inline volume control, a bulky design that is not foldable, and a somewhat muddy, warm sound signature that may lack high-end detail for discerning listeners.
