If you prefer wireless convenience and better noise isolation, go for the 1More Sonoflow, which also features longer battery life, making them suitable for extended listening sessions and air travel. However, the Koss Porta Pro offers a more open and spacious soundstage suitable for immersive gaming and video experiences, despite being wired. The Koss Porta Pro's on-ear, open design may be less isolating, which can be a drawback in noisy environments, but beneficial if you need to stay aware of your surroundings. Both have decent microphone quality for calls, but neither is specifically optimized for sports use. 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."
