If you prefer longevity in wireless use, the Sony WH-CH520 boasts a significantly longer battery life than the Sennheiser HD 250BT, making it ideal for extended listening sessions. For those prioritizing comfort, the Sony model also scores higher, which may be critical for prolonged wear. Gamers and movie aficionados should note that the Sennheisers offer lower latency with AptX LL support, enhancing sync between audio and visual content. The Sennheiser earbuds have better overall sound quality and noise isolation, which could be important for audio enthusiasts seeking a richer listening experience or use in noisier environments. Neither model has active noise cancelling, but if you often take calls or attend virtual meetings, the Sennheiser's higher mic quality might be the deciding factor. Give Feedback

"As a lightweight, robust audio provider with a long battery life, the Sennheiser HD 250BT offer a lot for their price: very good Bluetooth codecs, an app connection and an extremely understated design. These headphones may not be among the most comfortable, but they deliver adequate sound – without overdriving or distortion."

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."
