Choose the 1More Sonoflow if you prioritize longer usage with active noise cancelling and appreciate a balanced sound with decent isolation for a variety of settings including exercising and travel. However, for phone calls, and more durable build, along with a slightly more compact design and the convenience of wireless charging, the Marshall Major IV would be a more suitable option, albeit typically at a higher price. Keep in mind that the Major IV offers an exceptionally long battery life, which could be an important factor for extended use without frequent charging. 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."

Sound Guys
Jasper Lastoria | September 2023
"The Marshall Major IV shares quite a bit in common with its predecessor, but a key upgrade appears to be softer ear cushions. They make upgrading worth it. As a set of basic wired or wireless headphones the Major IV ticks most boxes by remaining easy to use, and fairly comfortable (at least, as on-ear headphones go)."
