If you value wireless convenience, noise cancellation, and the ability to use earbuds during exercise, the Bose Quiet Comfort Earbuds would be a better choice, as they are designed for active noise cancelling and are sweatproof, with a high comfort score. However, if the price is a significant factor and you prefer open-backed headphones for a more natural soundstage, or if you don't need wireless functionality, the Koss KSC75 would be more appropriate. The Koss KSC75 also has a longer history in the market and is known for its solid sound quality at a budget-friendly price, but it lacks modern features like a microphone or app-based controls.

"The Bose QuietComfort Earbuds is a great do-it-all option for anyone, so long as you can afford it. This is a great alternative to the Apple AirPods Pro and Sony WF-1000XM4. You can choose the degree of noise canceling, and enjoy premium features like automatic ear-detection. These earbuds merit an IPX4 rating, making them a fine workout companion."

"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."
