If you prioritize advanced features like focus tracking through neurological activity and better overall build and sound quality, the Master & Dynamic MW75-Neuro could be worth the higher price. They also offer active noise cancelling and aptX Adaptive for high-quality audio over Bluetooth, which the Sony WH-CH520 lacks. However, the Sony's offer excellent comfort, long battery life, and effective controls at a much lower cost. If you are budget-conscious, need something lightweight and don't require top-tier audio or noise-cancelling features, the Sony WH-CH520 headphones are a solid choice. Consider your willingness to invest in premium features versus the need for affordability and basic functionality. Give Feedback

Sound Guys
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."
