EarFun Air vs KZ ZS3

Analysis:

The EarFun Air is a relatively good Canal Earphone for people that are willing to spend around $40. The KZ ZS3, by contrast, is quite unremarkable and doesn't stand out in any meaningful way from other products at this price point.

In both cases, however, we recommend that you take look at some other options at the $40 and $16 budget ranges; in all likelihood you'll find some better alternatives.

If you're still interested in learning more about the EarFun Air and KZ ZS3, however, we wrote a summary of what we know about them:

Two highly trusted sources that perform well-thought-out in-depth testing consider the EarFun Air to be a great product - it earned the "Best for Waterproof Build" title from PCmag and "Ranked 3 out of 10" from CNET in their respective Canal Earphone roundups, which is a good indication of it being a notable product.

As for the KZ ZS3 - Head-fi, a source that conducts reliable hands-on testing, has featured it in its KZ-ZS3 Hifi High-End 3.5mm In-Ear Earphone Headphones Earpiece Original Headset Bass Earbuds With Microphone review roundup. However, it didn't make it to any of the top spots.

We conducted an analysis of all of the review data that we could find on these two products. First, we focused on sources that tested and rated both of them, like Head-fi, and learned that they all showed a preference for the KZ ZS3.

Then we took a look at the highest review scores that these two Canal Earphones received. We found that the EarFun Air managed to earn a rating of 10 from What Hi-Fi?, whereas the KZ ZS3 got its highest, 9, score from reviewers at Head-fi.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Canal Earphones on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Canal Earphones being 7.4 out of 10, whereas the EarFun Air and KZ ZS3 managed averages of 8.8 and 9.0 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct EarFun Air vs. KZ ZS3 comparison might not be entirely fair - some sources don't take value for money into account when assigning their scores and therefore have a tendency to rate more premium products better.
