The C630 are quite popular by now, and they are known by many names. Eventually, all of these names point to the same product: TIMMKOO C630, manufactured by Shenzhen Estron Technology Co., Ltd. for their own brand, TIMMKOO, intended for the international market, but they are also offered as an OEM product for many other brands and resellers.
Like many people have already noted, these earphones are amazing and are one of the best-sounding earphones on AudioBudget. Sure, the build quality leaves a lot to be desired, but the insanely deep sub-bass, balanced mid-bass, clear mids and sharp and crisp highs leave no room for debate that these earphones worth every bit of their price.
NOTE: I strongly recommend the black cable version. The white cable is aweful.
Sound signature: Balanced
Also known as: E-MI CI880, podoor J20, ZHIYIN C630, ALWUP UPC630, Malloom Water Drop, etc.
I had trouble get a seal with the stock tips, and had to use ROCK Zircon's amazing tips instead, and the results are excellent. These earphones are very comfortable, just like other similarly-shaped earphones in my collection. So just take in mind, you might not get a proper seal with the included ear tips.
Extremely deep bass, but you need to make sure you're using the proper tips for your ears. I had trouble get a seal with the stock tips, so take that in mind. The bass is stable and well-balanced, warm but not muddy at all. The main emphasis is on the sub-bass, which makes electronic music extremely fun to listen to.
Some of the best mids I have heard so far, and it's amazing that you can get that performance for such low price. The mids are upfront and emphasized, but not shouty and never fatiguing. The level of detail and clarity I'm getting out of them is quite stunning. It's safe to say that these earphones are mid-centric, because the mids are not recessed at all.
Super sharp and crisp. Borderline-piercing, but manages to keep sibilance out. Very impressive treble for such a price. If you're sensitive to sharp treble, you might have an comfort issue, but that true for most top-rated earphones.
