I'd say they're pretty similar, I have both brands in the style that have the arm, like airpods. I like my Dudios a little better than the Soundpeats, for sound. It is richer, and sounds more full. both fit very well, and both hold charge well, and connect easily. the only issue I have run into with my Dudios, is sometimes I have to forget and re-pair them with my phone, as the volume is not as loud. Not sure what happens there.
These are the 2 styles I have.

I prefer this style as I find they stay put better. I do have the other style like in the OP, but prefer the arm style. The ear part fits pretty flush as well, they don't stick out.
