So I've been looking into both the EarFun Air Pro 4 and the ROSESELSA Ceramics Ultra, and the comparison is actually pretty interesting. They cater to two completely different crowds. One feels like a safe, feature-packed daily driver, while the other leans heavily into a cleaner, slightly audiophile-ish vibe.
The EarFun Air Pro 4 goes for that classic Harman-style tuning. It is balanced, easy to listen to, and honestly works with pretty much any genre you throw at it. But tbh, it can feel a bit too “safe” and not very exciting. It sounds good, but it just isn't very memorable.On the flip side, the Ceramics Ultra offers a much cleaner presentation. You get a bit more clarity, and the vocals are pushed slightly forward. It is fantastic for vocal-heavy and acoustic tracks, but there is a trade-off: the bass isn’t super punchy. It provides a cleaner listening experience, but it might be less "fun" if you are a basshead.
EarFun packs a lot in here. The ANC is pretty solid for the price and includes a ton of modes, though maybe too many to be honest. It works really well for a noisy daily commute, even if it isn't quite class-leading.The Ceramics Ultra takes a totally different approach with a much more relaxed ANC. It doesn’t give you that aggressive vacuum seal that blocks out the entire world, but it feels much more natural and comfortable on the ears.
If you want tech, the EarFun wins easily. The low latency mode is actually useful, it has multipoint connection, and it is generally just a very feature-rich package. The Ceramics Ultra is exactly the opposite. It strips away the extra features to focus purely on sound, resulting in a much simpler, no-frills overall experience.This is where you will notice a huge difference. The EarFun provides a very “sealed” fit. It is very stable, but it can feel a bit intrusive for some people. It is secure but not the most breathable, and you might notice that plugged-up occlusion effect. The Ceramics Ultra is significantly lighter and less intrusive. If you wear earbuds for long work or study sessions, these are way more comfortable for casual use.
To summarize the comparison, if you want something feature-rich and reliable, the EarFun Air Pro 4 is the way to go. It does everything well, even if it doesn’t particularly stand out in any single category. However, if you want something with a cleaner and more relaxed sound, the Ceramics Ultra is the better choice. It definitely has a specific vibe, though it is not as versatile as the EarFun.
