If you're looking for wireless convenience with active noise cancelling for travel or commuting, and appreciate integrated controls for easy adjustments, the JBL Live 670NC would be a better fit, though it's more expensive. It has a built-in mic for calls, longer battery life, and is designed for durability. However, if you prioritize high sound quality on a budget, and don't need wireless functionality or noise cancellation, the Koss KSC75 has an open design which usually offers a wider soundstage. It's lightweight and may offer a more natural listening experience, but with less isolation from external sounds and no built-in microphone for taking calls. Give Feedback

"Let’s not insult the KSC75 by saying that it’s simply good for the price… because it’s far more than that. It basically has a monopoly at its asking price, and could still give modern budget headphones a run for their money 15 years after its release. The KSC75 is the world’s best not-headphone."
