If you're looking for earbuds with a more enclosed design and better microphone quality for calls and meetings, the Moondrop Chu is the better option, plus they are more portable due to their smaller size. However, if you prefer headphones with a more open design that often provides a wider soundstage, offering a feeling of space in the audio, the Koss KSC75 might suit you, but they have no built-in microphone for calls. Both have similar overall sound quality and neither are particularly well-suited for exercise or noise isolation. The KSC75 is less portable and has a slightly longer cable. Neither option supports wireless connectivity or noise cancelling technology. 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."
"These budget buds put the pressure on those premium priced in-ear monitors to really justify the cost disparity. Offering excellent sound quality at any price, the Moondrop Chu is both a perfect entry into the audio enthusiast hobby, and an all around good pick for music fans."
