Koss Porta Pro Remote On-ear Headphones, Black

The Koss Porta Pro is a set of on-ear headphones built with an open-back acoustic system. This design allows the user to remain aware of their surroundings while listening to audio. The headphones operate across a frequency range of 15 Hz to 25,000 Hz, with an impedance of 60 Ω and a sensitivity of 101 dB. A standard 1.2-meter cable provides a direct, wired connection to devices via a 3.5 mm plug.

For everyday functionality, the cable is equipped with an in-line microphone and remote. This control unit allows for volume adjustments and call management, such as answering or ending calls. The headphones are designed for portability, featuring a foldable headband that allows them to collapse for storage. An included carrying case provides protection during transport.
