Audio-Technica ATH-AD900 vs Sennheiser HD558

Analysis:

The Audio-Technica ATH-AD900X makes for a good, if unremarkable, Open-Back Headphone for people with a $170 budget.

The Sennheiser HD558, however, is merely mediocre at its $69 asking price, when compared to similarly priced products, and won't satisfy the needs of most people.

In either case, we suggest that you first take a look at some other options at the $170 and $85 price points before committing to one of these - it's likely that you'll be able to find some better alternatives.

If you're still interested in learning more about the Audio-Technica ATH-AD900X and Sennheiser HD558, however, we wrote a summary of what we could find about them:

The Audio-Technica ATH-AD900X was loved by reviewers at SoundGuys, a highly trusted source that performs reliable in-depth testing. It did great in its "Best Audio-Technica headphones" roundup where it was named its "Best open-back", which, in itself, makes it a product worth considering.

As for the Sennheiser HD558, it wasn't able to earn a top spot in any roundups from trusted sources that conduct their own hands-on testing. Nevertheless, it managed to impress reviewers at Expert Reviews, TrustedReviews, Head-fi, and What Hi-Fi? enough to make it onto their respective shortlists.

To get a better idea of how they fare when compared directly to each other, we analyzed review scores of sources that tested both. Head-fi, for example, preferred the Audio-Technica ATH-AD900X, while What Hi-Fi? rated both of them the same.

We also took a look at which sources had the best things to say about them. We learned that the Audio-Technica ATH-AD900X got reviewed the highest by Head-fi - it gave it a rating of 8.8, while the Sennheiser HD558 most impressed reviewers at Expert Reviews, which gave it a score of 10.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Open-Back Headphones on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Open-Back Headphones being 7.8 out of 10, whereas the Audio-Technica ATH-AD900X and Sennheiser HD558 managed averages of 8.1 and 8.9 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Audio-Technica ATH-AD900X vs. Sennheiser HD558 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.
