If budget is a concern and you're looking for a wired option with a microphone, the Koss Porta Pro would be a less expensive choice that offers good sound quality and portability with a retro design. However, if you prefer wireless convenience, better noise isolation, and possibly better durability due to the lack of wires, the Earfun Air Pro 2 might be worth the extra investment. The Earfun also offers active noise cancellation, which the Koss lacks, making it better for noisy environments. Keep in mind that wireless earbuds typically need recharging, while the Koss will work as long as your device has a headphone jack or you have an adapter. Give Feedback

"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."
