If you're looking for higher overall sound quality and comfort, particularly for extended use like during air travel, the Sony WH-CH520 might be a better choice, as they are over-ear headphones with longer battery life for wireless use. They also have built-in controls, are optimized for both Android and Apple devices, and include a microphone for calls. However, if you need something more portable and compact that is suitable for exercise, and if you prefer wired earbuds to ensure you don't have to worry about battery life, the Sennheiser CX300S could be more suitable, with the tradeoff being lower comfort over long periods and no built-in microphone. Keep in mind the higher price of the Sennheiser is due to the brand's reputation for build quality and sound, while the Sony offers more modern features, like app controls customization, at a budget-friendly price.

Major HiFi
Carroll Moore | April 2019
"Sennheiser offers impressive bang for your buck when it comes to the CX 300S. Built like a tank and sounding surprisingly good for such a budget-minded earphone, the CX 300S out-classes many of its would-be competitors. Functional but beautiful, it’s the perfect in-ear listening solution for anyone who wants to hear everything and look good doing it."

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."
