budget-friendly options, each offering different advantages. The Koss KSC75 headphones provide a very good overall sound quality, are better suited for TV and video with a good score, and have a unique clip-on open-back design that might contribute to a wider soundstage. However, these are not wireless, have no mic, and their build quality isn't as robust. On the other hand, the KZ ZSN Pro X earbuds offer good sound quality with a closed design that provides some noise isolation, a detachable cable, and better build quality, but they rank lower for activities like exercise and air travel. If your preference leans towards immersive open-back audio for at-home listening, go for the KSC75, whereas if you value portability, noise isolation, and the flexibility of a detachable cable, the ZSN Pro X might be the better choice. Neither option is optimal for calls or gaming due to poor mic quality, and both lack wireless capabilities and active noise cancelling. 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."
"The KZ ZSN PRO X offers superb sound for very little money, like under $30 USD. It has some rough edges with a plastic seam on the cable that can rub on your ear, and the bud is a bit large. The tech isn't cutting edge, but new doesn't always equal better. You should try it."
