The Koss KSC75 is a great choice for high-quality music listening due to its open design and dynamic driver, leading to strong overall sound quality; however, it lacks a built-in microphone and modern features like wireless connectivity. On the other hand, the Youthwhisper Bone Conduction Headphones offer a unique open-ear design that allows ambient sounds, making them safer for outdoor activities, and they are sweatproof for exercise. They also have built-in controls and a microphone, supporting calls and meetings. The Koss excels in sound quality for music lovers, while the Youthwhisper suits active individuals and multitaskers needing situational awareness and hands-free calls. Give Feedback

"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."

"If you're looking for a pair of headphones that can be worn while running or cycling, these Youthwhisper Bone Conduction Headphones are a great alternative to more expensive models. They're lightweight and compact, so they won't get in the way when wearing them while exercising. Plus, they have a built-in microphone so you can take calls during your workout without having to stop and fumble with your phone. The sound quality is great for this style of headphones, and it has many other cool features."
