Koss UR20
Neodymium drivers deliver an 18Hz-24kHz frequency response, 16-ohm impedance, and 97dB sensitivity, producing clear treble and deep bass from a lightweight 50g frame. The flexible sling headband allows single-sided monitoring and withstands daily wear, while the 8-foot cord suits home stereo or DJ booth setups. Best for budget-minded DJs and casual listeners needing a durable, long-cord wired headphone, but poor isolation limits it for calls and gaming.
