The popular NiceHCK store picked a high quality product to represent their budget-class offerings. The Bro model is identical in hardware and tuning to BGVP SGZ-DN1, thus the review is basically the same. One important difference to mention is the package contents. While SGZ-DN1 comes with basic stuff, the Bro comes with extra accessories for nearly the same price, which means more value for the price.
The sound is mainly bright, with a proper amoung of warmth and a bit boosted mid-bass, but nowhere near muddy. The sub-bass is excellent but not the deepest.
I would definitely recommend these earphones to anyone looking for a superb pair, with an excellent soft MMCX cable, and one of the most natural sound signatures around.
The earphones are extremely easy to wear, getting a perfect seal is straightforward thanks to the lack of any useless memory wires. My only complaint is that the housings are just too big and can put a bit of pressure on the ears for some users.
Lows / Bass
Excellent bass response, with more emphasis on the mid-bass rather than the sub-bass. The bass isn't as deep as, for example, Tin Audio T515. With that being said, the bass is stable enough and packs more punch than the likes of URBANFUN Hi-Fi and KZ ZS5.
Mids / Vocals
The vocals are warm just enough, not bloated and there's no muddiness in the sound at all. The vocals are leaning towards brighter tone, yet show absolutely no piece or sibilance. Even complex music styles, like black metal, sound absolutely amazing with these earphones.
Highs / Treble
Although not as sharp and crisp as URBANFUN Hi-Fi and KZ ZS5's highs, the treble on the Bro sounds more natural and neutral, but leaning to the bright side. From a comfort perspective, I find these earphones much easier to use for a prolonged time than those I mentioned, since they are not as piercing, which makes them suitable for a wider audience. I find the imaging of these earphones excellent, and vocal-oriented music pieces sound simply amazing on these.
