Koss UR 20 Headphone

It remains hard to believe Koss can make a full-sized closed-back headphone this substantial at this low, low price... but here it is. Perfect for many low-cost commercial and computer lab applications, or just for great budget personal listening, the UR-20 will isolate you nicely from outside noise and,as a huge plus, the UR-20 carries Koss' lifetime warranty. A simple, tough-built and easy-to-wear headphone highly recommended for classrooms, audio labs, auditoriums, museums, doctors/dentists offices, etc.

What We Think:
We really don't know exactly how Koss can manage to sell full-sized sealed headphones at this truly bargain price, much less ones that actually manage to sound decent... amazing! The Koss UR-20 is perhaps slightly bass-centric, which is why its a good candidate for bass lovers.  There's no question the Koss UR-20 remains a really incredible value-loaded buy for folks on an extra-tight budget or for commercial headphone applications like schools, computer labs, doctors offices, and museums. The Koss UR-20 larger sealed-back earcup effectively attenuates a good deal of ambient/environmental sounds while preventing headphone 'leakage' from disturbing others nearby. It's also a comfortable wear, which comes in handy for long listening at workplaces or computer stations.


The Koss UR-20 are a composite-plastic sealed [aka 'closed'] headphones with a size-adjustable headband and comfortable pleather earpad cushions. Although a bit large and oversize, they remain quite lightweight and ergonomic on the head given their dimensions. The UR-20 have an 8-foot non-detachable cord with a single-sided cable exiting the left earcup (no messy 'Y' cord tangles!) and the cord terminates to a stereo 1/8' (3.5mm) 'mini' plug. Consider the similar Koss UR-29 model if seeking an identical-performing headphone but with a convenient 'built-in' volume control adjuster on the cord. A full-size 1/4" plug adapter is handily included in the Koss UR-20 package. The sweet LIFETIME Koss manufacturer's product warranty remains in full effect, so just hang onto the receipt for free repair or replacement if they break.
