The Koss KSC75 clip-on headphones have an open design which can provide natural sound and a wide soundstage but offer little noise isolation, making them less suitable for noisy environments. The "Nothing" Brand Ear (2) earbuds are a closed-back design with active noise cancelling, better for sound isolation and more versatile for various environments such as air travel. The Koss KSC75 is a wired model that lacks a microphone and modern features like an app for customization, whereas the "Nothing" Ear (2) supports wireless features, a lower latency mode suitable for gaming and TV, and an app to customize controls and audio settings. If you prioritize high sound quality at a budget price and don't need noise isolation or wireless convenience, the Koss KSC75 could be suitable for you. Conversely, if you are willing to spend more for active noise cancelling, a microphone, and modern wireless features, the "Nothing" Ear (2) would be the better choice. Give Feedback

InEar Fidelity
Crinacle | June 2022
"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."

"For the price the Nothing Ear (2) is pretty good. It fits well, and the IP54 rating (and IP55 with case) is durable enough for daily life. Most of its unique features are found in the Nothing X app, such as personalized frequency responses, and personalized, adjustable ANC."
