If you prioritize having wireless earbuds with active noise canceling for travel and exercises, the JBL Live Free NC+ might be the right choice, but they are more expensive than the Koss KSC75. However, if you are looking for affordable headphones that offer better soundstage and are optimized for music and TV, and don't mind a wired connection, the open-back Koss KSC75 could suit you better. The JBL offers convenience features like an app equalizer and touch controls, while the Koss scores higher on comfort and is lighter, but lacks modern features like a mic and app integration.

"JBL has added great-sounding, rock-solid all-rounders with a pleasant, warm sound character to their range. They are equipped with a high level of functionality that can be customised via the app. Some compromises have to be made with the active noise cancellation, which has a discreet effect, while the ambient mode and the Talkthru function proved to be powerful despite a perceptible background noise."

"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."
