The Koss KSC75 offers solid sound quality and is budget-friendly, but lacks built-in controls and isn't the most durable. Its open design and ear hooks make it suitable for casual music listening and it's quite portable, but it doesn't isolate noise well, which could be an issue in noisy environments. In contrast, the Sennheiser HD600, while more costly, boasts superior overall sound and build quality, and a very comfortable over-ear design that's better suited for critical listening. Neither have a microphone for calls, and they both have open-back designs that don't block out external sounds, which could be an issue for use in public areas or for air travel. If your priority is top-notch audio with comfort at home and price isn't a concern, the HD600 is the better choice; if you're looking for affordability and a lightweight option that's easy to take on the go, consider the KSC75.

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."
