If wireless convenience is a priority, the Earfun Air Pro 2s are a solid choice with good sound quality, active noise cancelling, and sweatproof certification, making them suitable for exercise and air travel. They offer a longer battery life and the convenience of wireless charging. However, if you prefer a wired connection and want to save money, the KZ ZSN Pro X provides good sound quality with a larger soundstage, potentially offering a more immersive listening experience. They feature a detachable cable and are compatible with balanced audio cables, which may appeal to audiophiles on a budget. Keep in mind that the KZ ZSN Pro X lacks the wireless functionality, active noise cancelling, and extra features like sweatproof certification. Give Feedback

Headphone Addict
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."

Jasper Lastoria | April 2023
"The KZ ZSN PRO X offers superb sound for very little money, like under $30 USD. It has some rough edges with a plastic seam on the cable that can rub on your ear, and the bud is a bit large. The tech isn't cutting edge, but new doesn't always equal better. You should try it."
