This is perhaps the best Blon imo. For those with higher-end or more reference tuned gear, I can highly recommend the Blon as useful addition to your kit. The fit is excellent and allows for semi-deep fit that is still very comfortable (more so than Etymotic) while providing a good deal of isolation. The low profile also allows you to use these in bed even rest the side of your head against a pillow (though I wouldn't recommend sleeping with these on). Combine the very good build quality, decent cable, and a deep-yet-lively sound reproduction it makes a great set to use outdoors or for non critical use.
As far as sound quality, the BL-03 and BL-05S will be more closer to a reference target, and better for a wider range of genres. However, the Mini's presentation can become addictive in its own. Signature is similar to TFZ Live 3 and others looking to capture this dense-yet-lively sound character.
Of course detail and texture aren't going to be the best, but for the most part, the smaller 6mm driver performs very well, and can dig quite deep, just without the level of transparency you might get from a hybrid.
