If you're looking for studio-quality sound with a focus on clarity and detail, the Audio Technica M50x is preferred, especially useful for critical listening and professional applications. However, the higher price reflects this quality. On the other hand, the Sony WH-CH520 comes with convenience features such as wireless connectivity and a built-in microphone, making them more suited for everyday use, travel, and taking calls. If budget is a concern and you value wireless freedom and call functionality, the Sony WH-CH520 offers good value. Keep in mind that the more expensive Audio Technica will generally provide better sound quality, while the Sony offers greater versatility at a lower price. Give Feedback

"Good sound is timeless. It doesn’t matter that a number of years have passed since the ATH-M50x came out because it still works well. Since this wired headset doesn’t rely on batteries or Bluetooth technology, it’s bound to outlast its wireless counterparts. The no-nonsense performance, fit, and comfort of the Audio-Technica ATH-M50x make it worth picking up."

"If you’re looking for headphones that simply do what you ask them to: the Sony WH-CH520 is a decent option, even if it isn’t very exciting. Sony’s WH-CHXXX line fits this role quite well, and the WH-CH520 offers a decent raft of quality-of-life updates over its predecessor that should keep listeners happy. If the Sony WH-CH520 were a car, it’d be the boring-but-safe commuter compact."
