You can call them YueGuangBaoHe H1, but they are also known as TIMMKOO ES670, and as you might have guessed by now, they are also manufactured by Estron, the company that owns the TIMMKOO brand. Given these earphones' extreme design, you could have easily assumed that it is a product of some premium Japanese brand (I'm pointing at you, Elecom EHP-CH3000S).
For your information, YueGuangBaoHe is not a stranger. It is actually a subsidiary of aigo, a major company in China. While aigo deals with a variety of different products, YueGuangBaoHe's field of business is exclusively portable consumer digital audio equipment.
Both H1 and C630 have the same specified hardware, at least on paper. With that being said, you wouldn't be surprised if I told you that both earphones sound extremely similar. The main difference is H1's more pronounced bass. But quality-wise, they sound about the same. This probably has more to do with the different internal tuning, and by the substantially different housings.
Although the H1 are generally a little bit more expensive, and are harder to come by, the eye-catching design, excellent build quality and super-crisp and fun sound quality - these make them worth the investment. I definitely recommend owning these, at least if you still don't own a C630.
