The fancy BGVP brand changed their logo and released a new model called SGZ-DN1. Being quite unimpressed by a previous model, I wasn't expecting much from these, but I was wrong. Sure, the housings look a bit plasticy and cheap, and quite empty on the inside, but don't confuse design with sound. The sound is amazing. I've used these earphones for several days and was delighted how straightforward it was to get used to these earphones' sound.
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.
Super-clear and naturally-tuned sound quality. I'm amazed.
Super-soft and well-built cable, with a proper strain relief around the plug.
BGVP opted for standard MMCX connectors instead of proprietary ones, which makes customizing much more accessible.
I would happily substitute a bit of the mid-bass for more punch in the sub-bass.
The housings look unnecessarily large while being mostly empty on the inside, which doesn't help their first impression.
Might be uncomfortable to wear for some people because of their size.

Comfort & Fit
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 SGZ-DN1 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.
