Without access to specific details about the Earfun Air Pro 2 and Koss Porta Pro from the uploaded document, I can provide general advice based on typical characteristics of such products. If you prioritize portability and a wireless experience, you may prefer the Earfun Air Pro 2 earbuds, which likely offer noise-cancellation features and a convenient, discreet form factor suitable for commuting or gym use. On the other hand, the Koss Porta Pro headphones, which generally have an on-ear design, can provide more natural sound reproduction and might be more comfortable for prolonged listening sessions at home, but their wired design and larger size reduce portability. If budget is a significant concern, the Koss Porta Pro's lower price point could be attractive; however, if you value modern features like Bluetooth connectivity and active noise cancellation, the higher cost of the Earfun Air Pro 2 may be justified.

Peter Susic | September 2021
"There’s a lot to like about EarFun Air Pro 2. The best thing about them is the active noise cancellation, which works almost as well as the best true wireless earbuds out there. The audio quality is funky but enjoyable. Good dynamics and a wider soundstage save its presentation. Everyone, apart from the most diehard audiophiles, should be happy with it."

"It’s clear to see why these have been such a popular choice amongst listeners for nearly four decades. It’s a charming pair of headphones that delivers a truly enjoyable listening experience and one that I think punches well above its weight."
