Our Verdict
Koss Porta Pro Wireless
JBL T450BT Wireless
The JBL T450BT are slightly better headphones and offer a better value for your money when compared to the Koss Porta Pro Wireless. The Porta Pro Wireless have a more comfortable, portable, and breathable design than the JBLs. They also have a well-balanced and open sound that does not sound as sharp as the T450BT. They also have a slightly longer battery life, although not by much. On the other hand, the JBL T450BT have better noise isolation and leak a little less thanks to their closed design. They also have an easier to use control scheme and a slightly sturdier build quality, although not by much since they are mostly plastic.
