The Koss KSC75 are clip-on, open-back headphones with no wireless capabilities, offering good sound quality and a wide soundstage at a budget-friendly price, but are less suitable for noisy environments due to their open design and lack of noise isolation. They are also not optimal for exercise due to the lack of sweat resistance. The Sony WF1000XM3 are wireless, noise-cancelling earbuds, providing better privacy and immersion, good for travel and offices due to their active noise cancelling and closed design, with features like an app with equalizer settings and touch controls, but they are more expensive.

"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."

"Wireless earbuds are a dime a dozen, and the Sony WF-1000XM3 makes it easy to justify the cost. The design and comfort are good, and the connection strength is consistent. While the lack of aptX or LDAC support is a big drawback, DSEE HX processing improves low-quality audio files. If you want stylish active noise canceling (ANC) earbuds, the WF-1000XM3 needs to be at the top of your list."
