If price is a major factor, the Koss Porta Pro would be a cost-effective choice with very good music quality, but they have poor noise isolation and are not suitable for exercise or travel. The Sennheiser IE600, on the other hand, offers best-in-class sound, excellent build quality, and good noise isolation, making them suitable for quiet environments and providing a more immersive listening experience. However, the IE600s come at a premium price, and their poor microphone quality makes them less ideal for calls. Neither are optimal for gaming or use during exercise, but the Sennheiser's sound quality excels for TV and videos. Give Feedback

"It’s clear to see why these have been such a popular choice amongst listeners for nearly four decades. It’s a charming pair of headphones that delivers a truly enjoyable listening experience and one that I think punches well above its weight."
