RHA T20 (2015) vs KZ ZS3

Analysis:

The RHA T20 (2015) and the KZ ZS3 are decent Earphones at their respective price points, but don't manage to stand out from their direct competitors in any meaningful way. We suggest that you also look at some alternatives that can be found for around $250 or $10.

If you're still interested in learning a bit more about the RHA T20 (2015) and the KZ ZS3, however, read on for a summary of what we could gather about them:

While the RHA T20 (2015) wasn't able to make it to the very top of any roundups from sources that perform quality hands-on testing, it still got featured in a large number of them. Head-fi, Techradar, SoundGuys, HomeTheaterReview.com, What Hi-Fi?, PCmag, Headfonics, Audioholics, and Wirecutter (NYTimes) have all deemed it worthy of a place on their respective shortlists.

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.

When we thoroughly analyzed their review scores, we learned that all of the sources that tested both Earphones, including Head-fi, preferred the RHA T20 (2015) over the KZ ZS3.

We also took a look at which sources they managed to impress the most. The RHA T20 (2015) was liked best by Head-fi, which gave it a score of 10, while the KZ ZS3 got its highest, 9, score from Head-fi.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Earphones on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Earphones being 7.3 out of 10, whereas the RHA T20 (2015) and KZ ZS3 managed averages of 8.6 and 9.0 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct RHA T20 (2015) 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.
