If you prioritize sound quality for a variety of audio content and require advanced features like Active Noise Cancelling, low latency for gaming, sweatproof certification for exercise, and the convenience of wireless charging, the Sennheiser Momentum True Wireless 4 earbuds may be the better choice despite their higher cost. However, if you're looking for a comfortable, budget-friendly option with very good mic quality for calls and a remarkably long battery life for extended use, then the Sony WH-CH520 headphones could be more suitable, although they lack Active Noise Cancelling and have less effective noise isolation. Keep in mind, the earbuds offer greater portability, while the over-ear headphones can provide superior comfort for long listening sessions. Give Feedback

What HiFi
Andy Madden | January 2024
"It’s fair to say our brief time with the Sennheiser Momentum True Wireless 4 was a generally positive one. Comfort levels seem similar to what we have experienced before and the general flavour of sound was to our liking although we need to get a pair in to test and put up against the big rivals at the money from Bose and Sony. It could be an interesting contest."

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."
