If you prioritize excellent sound quality for music and a premium build but don't mind a higher price and no wireless capability, then the Sennheiser IE600 earbuds may be best for you. They're suited for high-fidelity listening, have a detachable cable, but lack features like a microphone, active noise cancelling, and app-based customization, which could limit their use for calls, gaming, and modern convenience. In contrast, the Sony WH-CH520 headphones are more budget-friendly and offer wireless convenience with very good microphone quality, making them a versatile choice. They are great for varied uses including gaming and video with virtual surround, and they have a long battery life. However, they may not match the Sennheiser's superior sound for critical listening and have a lower build quality. They lack active noise cancelling, making them less ideal for noise isolation in loud environments. Give Feedback

"If you've got the bucks, the Sennheiser IE 600 is a nice, upscale set of in-ear monitors made of a lightweight metal with an unusual texture. It comes with a suite of extras, and performs well at virtually every task."

"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."
