I had the cmf buds, I did like their sound but they were a bit heavy and they kept falling out. Also a bit difficult to clean up. I think I broke them while poking around with a cleaning stick, they no longer seal properly and sound bad. But while they worked they were overall pretty good. Noise cancellation wasn’t very good, it made music maybe slightly clearer in a noisy environment, but didn’t help enough so I rarely used it.

Nowadays I use Jlab Jbuds mini and they are the most comfortable earbuds i’ve ever had, they are so small and light they just feel great. Sound and battery is of course not best in the world, but for their size and price they are awesome.
