Koss Porta Pro
No noise cancelling, CableProduct details
The legendary Porta Pro from KOSS is a classic among portable hi-fi headphones. He has been successful on the market for decades and is still loved by many music fans. The Porta Pro delivers outstanding sound quality, with a sound rich in deep bass and a remarkably wide frequency response that provides detailed reproduction of a wide variety of musical styles. The version of the Porta Pro with microphone has a 1-button operation with microphone integrated on the headphone cable, so that calls can be taken and ended and the previous or next song can be played. In our opinion, the Porta Pro is one of the most comfortable headphones ever: once you put it on, you forget it completely. The movable ear cups with the comfortable air-permeable ear cushions guarantee a pleasant hearing experience even on long journeys or during sports. The pressure on the ears can be adjusted in two steps (fixed/light). When not in use, the Porta Pro can be folded to a compact 5 cm diameter and stored in the supplied carrying bag to save space.
