The 1More Sonoflow are closed-back over-ear headphones that offer wireless and wired options, a balanced overall sound quality with good noise isolation, a respectable comfort score, and a built-in microphone, making them versatile for a range of activities including music, calls, air travel, and limited exercise use. They feature active noise cancelling, a battery life suitable for extended use, app equalization for customization and additional features such as ear detection and a foldable design, enhancing portability. In contrast, the Koss KSC75 are budget-friendly, clip-on, open-back headphones with excellent sound quality for music, particularly noted for their soundstage. However, they lack a built-in microphone, active noise cancelling, wireless connectivity, and app features, making them more suitable for home use or environments with less noise where you don't need to take calls. They have a less robust build and don't isolate noise well, but are extremely portable and may be preferable for users wanting a lightweight and unobtrusive listening device for music or TV with natural sound. If budget concerns are less paramount and you need versatile, feature-rich headphones for a variety of settings and uses, the 1More Sonoflow may be the better choice. However, if you prioritize sound quality for music listening at home and are looking for a cost-effective option, the Koss KSC75 are an excellent choice. Give Feedback

"The SonoFlow is cheap and fun, without going too far into being overly warm or annoyingly grating, or sharp sounding. The ANC features are lovely with strong app integration and excellent battery life."

Crinacle | June 2022
"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."
