If you prioritize exceptional sound quality and have a higher budget, the Focal Elex would be a better choice; however, they're wired, bulkier, and less convenient for on-the-go use or exercise. The Sony WH-CH520, while less expensive and offering slightly inferior sound quality, provide comfort and convenience with a wireless option, lighter weight, a longer battery life, and are suitable for various activities, including calls, meetings, gaming, and travel. The Sony headphones also offer supporting features like an integrated microphone, app customization, and virtual surround, which the Focal Elex doesn't have. Give Feedback

Christian Thomas | September 2023
"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."
