If you prioritize wireless convenience and longer battery life for extended use, the Sony WH-CH520 headphones are a solid budget-friendly option; they also feature a comfortable over-ear design and are suitable for calls, meetings, gaming, TV and video. On the other hand, while more expensive, the Antlion Kimura Duo earbuds offer superior overall sound quality, excellent comfort, and are designed with a detachable cable and boom microphone, making them great for immersive music experiences and gaming, but they're wired and less portable than the Sony. Neither is sweat or dustproof, but only the Sony supports app customization and has active noise cancelling. Give Feedback

"Antlion Kimura Duo aren’t packed with features, but the ones they offer, work incredibly well. Especially the boom mic delivers very clean call quality with no distortion. If you explicitly look for gaming in-ear monitors with a reliable microphone, Antlion Kimura Duo are your best option."

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."
