Sony WF-1000X (2019) vs KZ ZS3

Analysis:

The Sony WF-1000XM3 (2019) is an exemplary product and sets the bar for all other Earphones at the $170 budget.

The KZ ZS3, however, is merely passable for its price. We suggest taking a look at some better options if you're considering buying a Earphone in the $11 range.

The Sony WF-1000XM3 (2019) managed to impress reviewers from many of the internet's most highly trusted sources, including SoundGuys, Laptop Mag, Rtings, PCmag, and Tom's Guide. It performed really well in their Earphone roundups - it was named "Top Pick" by SoundGuys, "The best noise cancelling wireless earbuds" by Laptop Mag, and "Best In-Ear Sony Headphones" by Rtings. That's high praise coming from sources that conduct in-depth hands-on testing.

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 Earphones received. We found that the Sony WF-1000XM3 (2019) managed to earn a rating of 10 from Techradar, 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 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 Sony WF-1000XM3 (2019) 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 Sony WF-1000XM3 (2019) 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.
