If you value high-end features like Active Noise Cancelling, wireless connectivity with long battery life, and a modern stemmed form factor with a smart charging case, the JBL Live Beam 3 earbuds would be a worthwhile investment despite their higher cost. These earbuds support the LDAC codec and are sweatproof, making them suitable for exercise and travel, though they're not optimized for gaming or TV due to latency concerns. On the other hand, the Koss KSC75 headphones are a budget-friendly choice with very good music quality and an open-back design, which generally offers a natural soundstage but lacks features like a microphone, active noise cancelling or wireless capability and has poorer build quality. Their open design means they won't isolate noise well and aren't suited for noisy environments, but the clip-on form factor offers light wearability for casual listening. 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."
