If you prioritize exceptional sound quality and comfort for extended listening sessions, the Sennheiser HD800S is an unparalleled choice, especially for an immersive music experience due to its wider soundstage. However, they come with a higher price tag and are less portable, which, coupled with their open design, makes them less suitable for noisy environments or on-the-go use. The Koss KSC75, while significantly more affordable and offering good audio performance, doesn't match the Sennheiser's sound detail and comfort. They're more portable and better suited for light exercise but lack features such as low latency, making them less ideal for gaming or watching TV. 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."
