UiiSii DT200

2 × ø6mm Dynamic Drivers


While the DT200 are mainly sold in China, a model known as BA-T8 is mainly sold internationally, and as far as I'm aware - these earphones are identical and only the package and its contents are different (for example: the DT200 comes with a case, while BA-T8 comes with a pouch). The BA-T8 has been praised in some circles as good-sounding earphones, but no comparison to DT200 was made to confirm that they are idential. Personally, I found absolutely nothing impressive about them. Basic build quality and a very unsurprising sound quality. The sound is mainly warm (a bit too warm for my taste) with veiled mids and highs. The mids are emphasized but are not highly detailed and not exactly pleasant, even harsh sometimes. The highs devoid of any brilliance, are absolutely simple-sounding.

Considering the price of these earphones, I expected much more in terms of sound quality.

Comfort & Fit

Just like most earphones with a similar design, these earphones are also very comfortable and putting them in is very straightforward. The wings on the side which are supposed to hold against your ear are made of soft silicone and are very soft, so they will never make your ears sore, unlike WRZ X7, for example.

Lows / Bass

The bass is responsive, but not exactly deep. Most of the emphasis is on the mid-bass, which adds a bit muddiness to the sound. I wouldn't choose them for electronic music either. There is just not enough punch in the lower-bass to compensate for the mid-bass bump.

Mids / Vocals

The mids are weird, simply put. They are quite loud, but tonally sound inaccurate, even darkish. I actually browsed through some of my cheaper earphones and found them to be much more crisp than the DT200.

Highs / Treble

The highs are recessed and tonally inaccurate. Claps sound harsh and guitars sound blanketed. There is an overall lack of brilliance that makes a boring and unimpressive experience.
