The Earfun Air Pro 2 is a more budget-friendly option with good overall sound, comfort, and excellent noise isolation. They are wireless, include active noise canceling and sweatproof, suitable for exercise, and have a decent battery life, which makes them versatile for everyday activities. However, if you prioritize sound quality, particularly for music and a more natural soundstage, the Etymotic ER4XR may be more appealing despite being pricier. The ER4XR has a higher sound quality for music and is better for TV and video due to its wired connection which ensures low latency, but lacks features like a microphone, wireless connectivity, and active noise canceling.

"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."

"The Etymotic ER4XRs' top qualities are the detail and definition of the midrange, rewarding the closest listening. While the soundstage is large rather than gigantic, the excellent separation and spatial precision mean you can dive deep into music just as much as when wearing a pair of full-size open-backed headphones."
