The 1More Sonoflow headphones offer superior overall sound quality, better noise isolation, and come with wireless capability as well as a longer battery life, making them a good choice for longer listening sessions and travel. They also have LDAC for high-quality audio over Bluetooth and are suitable for exercise given their sweatproof feature. However, they are heavier and larger, which could be less convenient for portability. On the other hand, the Sennheiser CX300S earbuds are lighter and more compact for easy carrying. They offer better sound imaging but lack a built-in mic, wireless functionality, and active noise cancelling. The Sennheisers may be better suited for wired listening and situations where compactness and fit are priorities. 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."

Carroll Moore | April 2019
"Sennheiser offers impressive bang for your buck when it comes to the CX 300S. Built like a tank and sounding surprisingly good for such a budget-minded earphone, the CX 300S out-classes many of its would-be competitors. Functional but beautiful, it’s the perfect in-ear listening solution for anyone who wants to hear everything and look good doing it."
