Introduction
BGVP is a Chinese brand that produces in-ear monitors (iems). They are known for their Sidy iems and have produced other iems such as YSP04 and DGS100. Recently, they have released 2 new iems – SGZ DN1 and DM5. I would like to thank Penon Audio and BGVP for this review unit. As of now, you can buy the SGZ DN1 from https://penonaudio.com/SGZ-DN1. In this review, I will provide my impressions on it.
Specifications
The BGVP SGZ-DN1 comes in a package with a black protective cover that sports the BGVP brand name. At the bottom of the cover front, there are words – “THE BEST EXPERIENCE”. At the bottom of the cover back, there is a sticker showing the specifications of the iem. Finally, the cover side is similar to the cover front except that the name and slogan are all packed closely together.
After removing the cover, there is an open package with the iems and a small black box.
The small black box consists 3 pairs of black silicon tips, 1 pair of blue foam tips, 1 shirt clip and 1 cable with microphone.

Cable with Microphone
The material being used to make this cable is oxygen-free copper. The cable has mmcx connectors with Left and Right markings on the matte black housing to indicate the respective side. The y-splitter is silver in colour. Lastly, the 3.5mm gold plated jack has a silver housing with strain relief.

IEM Build & Design
The iem has a plastic shell with the faceplate in a smooth silver finish and the rest is translucent black with golden glitters. Both the left and right side of the iem are similar. There is a dark grey BGVP logo on the faceplate. On the inside of the iem, there are 3 vents. At the side of the iem, there are words – “SGZ DN1 Single BA Driver Hybrid IEM Earphone” printed in white colour. The nozzle is slightly angled and there is a metal mesh for earwax prevention. Overall, the build on the iem is average and it has good ergonomics. Personally, I find it light weight and it sits in my ears comfortably.
Cable Build & Design
The material being used to make this cable is silver-plated oxygen-free copper. The cable is quite flexible and soft. It has a shiny look. The mmcx connectors are the same as the cable with microphone. There are markings on both sides to indicate left and right. The chin slider and y-splitter are matte black in colour and rectangular in shape. The jack is right angled with strain relief. It is 3.5mm gold plated with a matte black housing.

Sound Analysis
Lows
The SGZ DN1 has an average sub-bass extension. There is a good amount to it. The rumble is quite nice and slow. The mid-bass is rather smooth and it presents itself in a manner with not much authority. The bass is warm and smooth. Bass decay is average and each bass note is expressed slowly. The quantity of the bass is quite good but I feel the texture needs to be rendered better. The transition to the midrange is well done due to the bass nature. With warm and smooth bass, it is soothing to listen to. The technicality of the bass is lacking but the musicality is spot on.
Mids
The midrange operates in a smooth manner and I find it rather neutral with a slight emphasis on the lower mids. The lower mids has quite a lot of quantity and the upper mids are not very forward. The details retrieval is average. The midrange is more towards the warm side. The musicality is quite good with details slightly lacking. Resolution is decent and layering is average. It is the type of midrange that is smooth and not offensive. You can listen to it for quite a while. Overall, it is laid back and smooth.
Highs
The treble is not extended very well. Personally, I find the treble is smooth and there is no graininess to it. Energy is slightly lacking due to no sparkle. There is no sibilance and harshness. The amount of air is average and it plays a part so as to lighten the sound. The details are just what you will expect from an iem at this price point. The treble is smooth and polite. There is a decent level of definition to it. There is not a lot of treble quantity but the smooth nature of the treble is nice.
Soundstage
The soundstage has an average width and depth. The width aids in the imaging and positioning of instruments and vocals. Layering is decent and the sound is slightly congested. There is an average expansion in stage.
Comparisons
I use the iBasso DX200 for the comparisons.
BGVP SGZ DN1 vs BGVP DM5
The sub-bass quantity is more on the DN1 but the extension is better on the DM5. DM5 is better in the bass quality as it is being articulated with more precision. The mid-bass of the DN1 has more quantity but lacks the quality in the DM5. Bass quantity is better on the DN1 but for quality, the DM5 is more superior. The bass texture on the DM5 is more defined and each bass note is more clear with faster decay. The lower mids on the DN1 is much thicker than the DM5 and it makes the sound more dense. This slows the overall nature of the sound. The upper mids of DM5 is more forward and organic. The details retrieval of DM5 is better than the DN1. For the treble section, DM5 has more air and presents it in a clinical manner. In addition, there is a higher level of details retrieval in the DM5. The DM5 excels in both the width and depth of soundstage. Instrument positioning on the DM5 is more precise along with its resolution.
BGVP SGZ DN1 vs Kinera BD005E
The SGZ DN1 has more sub-bass quantity and less extension than the BD005E. The SGZ DN1 goes more deep. The mid-bass on both is similar and there is good articulation on both. The bass texture is rendered around the same on both. Bass note on the SGZ DN1 is being presented with more authority with a quicker decay. The lower mids on the SGZ DN1 has more body and sounds thicker as such. The midrange of the SGZ DN1 is more smooth. For the upper mids, the DN1 is equally forward as the BD005E. In the treble section, SGZ DN1 has a better extension and clarity. There is just more air. The sparkle on both is around the same. SGZ DN1 and BD005E has similar soundstage in terms of width and depth. Vocals and instrument positioning on both are average. The resolution of SGZ DN1 is better.
BGVP SGZ DN1 vs TFZ Exclusive 1
The SGZ DN1 has similar sub-bass quantity and extension as the Exclusive 1. Both are at the same level with SGZ DN1 slightly ahead as there is more punch to it. The mid-bass quantity on the SGZ DN1 is more and this improves the overall dynamics. The SGZ DN1 has its bass texture rendered better. The bass note is better presented on the SGZ DN1 and the decay on both is around the same. The lower mids on both is around the same with a good amount of body. The upper mids on the SGZ DN1 is more forward and smooth. Both have similar clarity. Moving on to the treble, the SGZ DN1 has more air and details. Both have decent sparkle. In terms of soundstage, they have similar width and depth but SGZ DN1 has better width. Vocals and instruments positioning on both is decent. The resolution is similar.
Conclusion
The BGVP SGZ DN1 is a smooth sounding iem with more emphasis on the lows. I find it fit comfortably in my ears and with the smooth nature of it, one can listen to it for a long listening session. It has good bass quantity, clean midrange and smooth treble. Featuring detachable mmcx, the SGZ DN1 can be used with other cables too. It is a good affordable iem with a smooth signature.
