Audio-Technica ATH-M40x (2014) vs JBL Live 400BT

Analysis:

The Audio-Technica ATH-M40x (2014) is one of the very best Closed-Back Headphones that one can get for around $100. The JBL Live 400BT, however, while a very good choice at its $55 price point, falls just short of being remarkable.

The Audio-Technica ATH-M40x (2014) got praised by SoundGuys and Rtings - two highly trusted sources that perform in-depth hands-on testing. It was awarded the "Best All-around" title from SoundGuys and "Runner Up for Best Over-Ear Headphones Under $100 For Audiophiles - Closed-Back Alternative" from Rtings in their respective Closed-Back Headphone roundups.

As for the JBL Live 400BT, it was really well-received by reviewers at Rtings, a reliable source that's known for conducting its own, high-quality, in-depth testing. It performed great in its "The 6 Best On-Ear Headphones - Spring 2020" roundup and was named its "Best On-Ear Headphones For Running", which, on its own, makes it a product that warrants a closer look.

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 Rtings, and learned that they all showed a preference for the JBL Live 400BT.

Then we took a look at the highest review scores that these two Closed-Back Headphones received. We found that the Audio-Technica ATH-M40x (2014) managed to earn a rating of 9 from SoundGuys, whereas the JBL Live 400BT got its highest, 7, score from reviewers at Rtings.

Lastly, we averaged out all of their review ratings and observed that the Audio-Technica ATH-M40x (2014), with its 7.6 average, performed considerably better than most Closed-Back Headphones - the mean score for the product category being 7.4 out of 10 - while the JBL Live 400BT managed an average of 7.0.

There's one caveat here - it might not be entirely justifiable to do a direct Audio-Technica ATH-M40x (2014) vs. JBL Live 400BT review average comparison since they aren't priced the same and more expensive products tend to get higher review scores from some sources.
