The Koss KSC75 offers great value for music listening with strong sound quality and comfort, particularly given its significantly lower price. However, its open-ear clip-on design provides minimal noise isolation and could be less suitable for noisy environments. The Philips Fidelio X2HR, on the other hand, excels in soundstage and overall sound quality, making them excellent for an immersive music and video experience. These headphones, while more expensive, come with a detachable cable and are more comfortable for extended wear, making them a good choice if comfort and sound immersion are priorities and you are willing to invest more. Neither model has a microphone, so for calls and gaming, you might want to consider other options, and both being wired with open-back designs are not ideal for exercise or travel due to lack of noise isolation and portability.

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."
