I have what I consider 'mid' sized outer ears, and I can only used the smallest ear guides / fins that come with Alpha 1. The mid and large sized fins are simply too big to fit me. Without the fins, I can't get a decent fit so the fin-less options don't work for me either. It is indeed not for people with small ears, and probably not for those who are not partial to earbuds (over IEM).
With a good fit, the overall tuning is actually closer to an IEM, as it doesn't have the openness of earbuds. While still quite good sounding, I think the 'hybrid' part of Alpha 1 might better describe the sound signature rather than the two types of transducer. If you are looking for the 'open-end' feeling that typical earbuds offer, this might not be your cup of tea. But if you are not, this might work.
DUNU has created something very unique with Alpha 1, but it is not for everyone. If you are looking something safer to try, Titan 1 is an absolute gem that I can recommend without hesitation.
