I was quite interested when I saw this lovely H2 by beteno (also known as "bidenuo"). I was disappointed when I saw how basic their build quality actually is, and how below-averege their sound quality is. Punching lows (although not much sub-bass), uncomfortably loud and dark mids, almost absent highs.
They are quite comfortable to wear, but overall, you souldn't waste your time in search for those, in my opinion.
A powerful mid-bass.
They get quite loud.
The housings have some interesting design to them.
You get a tiny case and a shirt clip with these.
Overall dark and unnatural sound signature.
Overemphasized lows, lower-mids and mids cause the sound to be generally uncomfortable.
Sounds even worse at higher volume levels.
The overall build quality is quite poor.

Comfort & Fit
These earphones are shaped very well and provide a great seal while staying firmly in the ears. Thanks to their form, you don't have to force them in to get a perfect seal. Moving around will not cause them to fall out.
Lows / Bass
Weak sub-bass but excessive lows and lower-mids. The kicks are loud but there's nothing fun about it, they are loud in a very unpleasant way, like someone's hitting a hammer against a wall near you.
Mids / Vocals
Overemphasized but also inaccurate. You'll get the sensation like someone's shouting directly into your ears. It's uncomfortable and headache-inducing. Moreover, the mids are inaccurate and lack detail.
Highs / Treble
Inaccurate and lacks any detail and brightness. There's very little to say about them, except that they are plain dull, exhausted and dark and are completely overrun by the excessively loud mids.
