Choosing between the AKG K712 Pro and the Sony WH-CH520 involves several trade-offs. The AKG K712 Pro, while pricier, offers superior sound quality and soundstage, making it an excellent choice for critical listening and an immersive music experience. However, they're open-back, meaning they don't isolate noise well and are not suitable for noisy environments or recording. The Sony WH-CH520 is more budget-friendly with good sound quality, and as a closed-back design with a longer battery life, they are better for travel and outdoor use. The Sony also includes a built-in microphone for calls and active noise cancellation for loud environments. If you need a wireless option and use headphones for calls or active noise control, the Sony may be more suitable; but if you prioritize audio fidelity for home listening, the AKG K712 Pro could be better.

"AKG has created a mini-masterpiece in my opinion. I enjoy this headphone a great deal and it will become my go-to reference headphone for the time being. She is slick, sexy, well-balanced, and crazy comfortable."

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."
