If price is a primary concern and you're looking for headphones that provide good overall sound quality and comfort, the 1More Sonoflow might be the better choice, especially since they offer very good noise isolation for air travel and are suitable for use during exercise. However, if you prioritize exceptional sound quality and don't mind using a wired connection, the Sennheiser IE600 could be worth the premium price. They also have superior build quality and are optimized for high-quality audio content like music and TV, but they're not as versatile for activities such as exercise due to the lack of wireless connectivity and active noise canceling. Both options offer good portability, but the Sonoflow has the added convenience of wireless use and longer battery life. 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."

Jasper Lastoria | August 2023
"If you've got the bucks, the Sennheiser IE 600 is a nice, upscale set of in-ear monitors made of a lightweight metal with an unusual texture. It comes with a suite of extras, and performs well at virtually every task."
