If you're looking for versatility with both wireless and wired options, active noise canceling for quieter listening environments, and built-in controls, the Earfun Wave Pro headphones are a great fit; they are also well-suited for calls and meetings. However, these features come with a higher price. In contrast, the Koss KSC75 headphones are more budget-friendly, offering very good sound quality with an open design for a more natural sound and wider soundstage, but they lack a built-in microphone, noise isolation, and the durability and features of more premium models. If you prioritize cost savings and sound quality over additional features, the Koss KSC75 could be the better choice. 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."
