Our Verdict
Audio-Technica ATH-M50x
Sony MDR-7520
The Audio-Technica ATH-M50x are a better value than the Sony MDR-7520. The Sony have a more premium and durable build quality when compared to the Audio-Technica. They also have a lower profile on your head and an understated look and feel that some may prefer over the slightly plasticky design of the Audio-Technica. On the other hand, the Audio-Technica are more comfortable.
