If you prioritize sound quality and build, the Sennheiser HD 350BT may offer a more precise and immersive audio experience, often preferred by audiophiles. However, the higher price reflects this quality. On the other hand, the Sony WH-CH520 is more budget-friendly and could still provide decent sound performance for casual listening. If features like noise cancellation, battery life, and portability are important to you, you might want to consider how each model compares in these areas before making a choice. Additionally, think about the comfort and fit for long-term wear, which can vary between individuals. Give Feedback

"Sennheiser nails just nearly everything about the Sennheiser HD 350BT headphones. Sound quality is excellent, and the high-quality Bluetooth codec support is a rarity at this price point. If you don’t care for high-tech features like automatic ear detection, you’ll be delighted with these portable headphones."

"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."
