Koss UR20

The Koss UR-20 are below-average headphones that perform poorly in most of our test categories. They are moderately comfortable but have a weak, unexciting sound and leak quite a bit. People around you will hear your audio at high volumes, and they only provide passive isolation from ambient noise.

If you prefer over-ear headphones, the best headphones under $20 that we've tested are the Koss UR20. These lightweight headphones have a comfortable fit that makes them suitable for long listening sessions.
