If you prioritize high-quality sound for music and immersive audio experiences, and often engage in air travel where noise cancellation is a benefit, the Focal Bathys are likely your better choice despite the higher price point. They offer superior overall sound quality and active noise cancellation, which Koss KSC75 lacks. However, if you're looking for something more affordable for casual use, and active noise cancellation is not essential, the Koss KSC75 are much more cost-effective and still provide a good sound. The KSC75s also have a clip-on, open design which makes them convenient for light exercises and situations where you need some environmental awareness, although this design may be less immersive and offers minimal noise isolation compared to the closed design of the Bathys. Additionally, the Bathys provide wireless connectivity and app customization options, which are absent in the Koss KSC75. Remember that the Focal Bathys being more recent also have better features like ear/head detection and a significantly longer battery life, enhancing their usability in wireless mode. Give Feedback

"As much as I hesitate to recommend a headphone that sells for $800 USD, if you’re looking for the best sound quality you can find in the ANC space: it’s the Focal Bathys."

"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."
