If you prioritize sound quality for music, the Koss KSC75 offers better performance. However, if you are looking for a headset that includes a microphone for calls or gaming communications, the JBL Quantum 100 is equipped with a boom mic that provides excellent voice quality. The Koss KSC75 likely won't support your needs for calls as it does not include a mic. The JBL Quantum 100 could also be preferable for gaming due to virtual surround features and the closed design that helps with noise isolation. However, the Koss KSC75 has an open design, which could provide a more natural listening experience and is more comfortable for long sessions, according to its comfort score. Keep in mind, Koss KSC75 is typically less expensive, so if you are on a tighter budget and don't require a mic, they might be the better choice. Give Feedback

CNN Underscored
Wes Davis | July 2023
"I appreciate a functional piece of tech as much as I do gear on the bleeding edge, and the JBL Quantum 100 certainly falls in the former category. The sound is reasonably good, the built-in microphone is surprisingly reliable and it has a thoughtful design for the price. It lacks the convenience of Bluetooth, sure, but sometimes it’s nice not to have to worry about the finicky nature of wireless communication and go with good old hard-wired tech."

"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."
