The Koss Porta Pro headphones have been a staple to many audiophiles for over 30 years and have seen very few upgrades over this time, but Koss has finally updated this staple with a new Bluetooth version. The new Koss Porta Pro Wireless headphones are almost identical to their wired counterparts, but they feature a slightly thicker wire connecting the two earcups together. This wire also features an inline battery module, Bluetooth pairing controls, as well as mic and volume controls.
In terms of performance, the new Porta Pro headphones feature a similar sound quality to the wired versions. The balance is just as good as its predecessors, but the wireless models do feature more robust bass and a mild treble. The wireless Pora Pro headphones feature 12-plus hours of battery life and come with a one-year warranty.
