BGVPDMG Review.

BGVP DMG on my hand

The BGVP DMG was sent free of charge by Lillian the co-founder of Linsoul. I’ll try my best to give an impartial opinion about the gear*.
Below I share the links to the store which provided the samples I’ll be reviewing, keep in mind that without the cooperation of this store I would probably not review this gear.

Introduction
My introduction to BGVP first started with the SGZ-DN1 hybrid in-ear, a simple but really good sounding budget earphone, so I was rather curious to hear the DMG.
Well, after more than a week using it daily, I’m happy to say the DMG is my new reference on the 100 to 200€ price range.
Also keep in mind that it’s possible to change the nozzles of this model so my review is made with my favorite nozzle, the silver one which doesn’t have a filter thus showing the true treble of the DMG.
Supposedly the gold one enhances bass and the one with the original color of the in-ear is the balanced one. There are subtle differences between both so if you enjoy bass or want a “tamed” treble, these nozzles are the way to go.
A word of advice, the screw on nozzles should be used and stored with some care, because they are really easy to lose.

Testing rig
As a typical portable rig I’ll be using my Sony L1 (G3311) smartphone and Spotify on the higher quality setting without any EQ, normalization or any other gimmick.

My daily driver will be a uncapped Sony Walkman A-45, with both lossy 320kbps Mp3’s and lossless 16-Bit 44.1Khz Flac music files, I might use higher resolution if necessary.

On the desktop/laptop side I’ll be using a Creative Labs E5 DAC, again with Spotify on the higher quality setting and without any gimmicks just like the Sony L1, and of course the DeaDBeeF music player for Flac music files at 16-Bit 44.1Khz but with some exceptions.

I won’t be reviewing the interaction of all sources with the in-ear for obvious reasons, so for simplicity sake the review below will use the Creative Labs E5 to drive the in-ears unless stated otherwise.

A look inside the box

As usual the box arrived warped in plastic, to reach the contents one must slide a promotional sleeve with a DMG printed against a white background and remove the top cover of a simple but pretty box.
Inside you will find a small box with the in-ears inserted in foam, another box for the accessories and the bottom cover which hides a beautiful silver cable (no microphone in my case) , booklets and quality control stamp.

The accessories box includes, 3 sets of silicone tips in a large, medium and small size, 1 pair of medium foam tips, 1 pair of ear hooks, 1 cable clip, 1 small plastic box with 2 pairs of screw on nozzles (Silver and Gold).

All of these accessories come inside small plastic bags, sadly not the most environment friendly option but a necessary evil when you must pack so many small accessories.

When I unpacked the DMG’s I felt a bit overwhelmed by opening tight boxes and so many plastic bags, the silicone tips had 3 separated bags and BGVP could easily use only one bag for them. The small plastic box that came could easily store the foam tips, and the nozzles had their own separated bag so I don’t see the need for them to be packed inside another box.
I think BGVP needs to simplify their packaging and help the planet in the process.

Built quality & specifications
The DMG’s build quality is solid, from the magnesium-aluminum alloy shells to the silver plated cable, everything looks beautiful and feels great to hold. BGVP did everything right on this entry level earphone.

My shells were painted in a metallic red color, the quality of the painting looks great, I don’t see any blemished. The factory did an amazing job with these specially given the price range. Even the model number and serial number look perfectly centered on the top of the shell.
The shells have no right/left markings on them, but each connector has a ring around it with the color of the plug that should be connected.
There is a small rectangular vent on the top and a small venting hole on the back of the shell, curious enough the marketing images show a small venting hole facing the outside, which isn’t present on my version.

Like I said before it’s possible to screw on different nozzles on the in-ear body, I don’t recommend that you do this procedure many times, because sooner or later the nozzle thread will fail or you might lose a piece given their size.

The connector socket looks well build but there is a slight play between the connector and cable plug.

The MMCX cable plug on the silver plated cable is made of some kind of metal and there isn’t any kind of strain relief in it, the plastic sleeve that goes around the ears feel malleable and doesn’t have a wire guide. I personally don’t like wire guides around the ear, unless the in-ear is heavy, not the case here.

Now the cable, well the one that I received is very pretty, keep in mind that the microphone version of this cable is different from the silver plated one.
Some people love cables others like me are more practical, but I’m sure most people still enjoy the work that goes in to making a beautiful cable like the one provided with the DMG.

The cable that came with my sample isn’t braided, it was molded to coil both cable conductors around each other. This means that with time the cable might start losing it’s shape.
The Y-Split looks solid and just like the plugs lacks a strain relief, there is a chin slider that sadly doesn’t keep it’s position.
The cable ends in a 3.5mm L-shaped plug, thankfully there is a decent strain relief on the jack. As you probably noticed, I hate when companies don’t put strain reliefs on their cables, it’s my pet peeve.

The cable impedance at the ground line should be around 1Ω as measured with my simple UNI-T UT601.

Well as accessories go, the DMG brings enough silicone tips for newbies and veterans alike, the foam ones are a nice touch.
On my review I didn’t use any stock tips that came with my sample because I like the KZ “starlines”, keep in mind this is a personal choice. Also yes, I know the nozzle is too large for the “starlines” but I dislike tips with wide nozzles.
The ear hooks, cable clip and little plastic box are a nice touch.

My only complain is that lack of a semi-hard case, BGVP could have saved on the plastic bags and little boxes and packed a transport case.

Everyone likes specifications so here are some I could find:
– 2 dynamic drivers (coaxial) with a graphene + titanium coated diaphragm and 4 balanced armatures per side (Knowles custom 10006 medium-high dual BA and the Knowles SWFK-31736 high dual BA).
– Frequency response: 15Hz – 45KHz
– Sensitivity: 110dB/mW @ 1KHz
– Impedance: 18Ω (34Ω on my UNI-T UT601)

Daily use
This model was very comfortable to use during my commutes, but sometimes I would lose the seal because the nozzles didn’t go very deep. You can play around with the provided tips or just use the foam ones, if you face the same problem.
The DMG’s are not heavy or have sharp angles thus they should sit nicely on most ears.
Noise isolation wasn’t that great, again keep in mind the nozzles didn’t go very deep.
On the subway you will probably need to dial the volume up a bit, again only a problem in very loud places and if you have similar ears to yours truly.

Sound
The DMG was a bit of a challenge to review because my reference for in-ears is the Yinyoo HQ5 which isn’t very well known by the community.
In reviews one must compare gear, my problem is that besides the HQ5 I don’t have better in-ears on the 100 to 200€ price range. At that price range I rely on my Beyerdynamic DT880 and DT990.
Even if I did it in the past, I don’t want to compare full size headphones with in-ears, so I will give my opinion without making comparisons with other models, try to bear with me.

The lower end coaxial dynamic driver does a great job on tracks that require impact and control over the bass, “Tan Dun – Gone with leaves” drums nuances are all there without removing the details of the other string instruments.
The bass and dare I say the sub-bass are so dynamic that sometimes I forget I’m using in-ears.
Also it came to my attention that some people who bought this in-ear complain about the bass, well in terms of quality control Chi-Fi in-ears still need to catch up to European and US brands, in matching the frequency response between samples.

I love Cher, she’s one of my many guilty pleasures, “Walking in Memphis” is a track that I know well from my teenager years. It’s a very layered song with lots of information on the mids, so unless a headphone has good detail retrieval on those frequencies, things will sound messy. The DMG delivers a great song without making the song sound like a bloated mess, the mids stand on their own and the bass gives that extra push without veiling Cher’s voice or the choir.
I like female voices, Cher boyish voice on “It’s a man’s world” album is a joy to hear with the DMG’s, unlike some reviewers I don’t like to use the same songs over and over again.
It sucks the joy of the hobby, I do this for fun not for likes, ass kissing or money so yea I indulged in some foot tapping when I reviewed the DMG’s.

Treble wise, these are just the way I like it, brutally detailed but tamed enough not to make me want to remove the in-ears after a long session.
Joe Satriani – Summer song” has an amazing guitarist at the helm, but the drums are also phenomenal, the little splashes are all present in headbanging fashion.
It’s a song that makes all good things about the DMGs stand out, from the punchy bass to the detailed electric guitar and fantastic drumming, everything fall in place with the DMG.

I think all good reviews about this in-ears are correct and I must join my voice to the chorus, BGVP has a winner with the DMG. Also sorry for taking so long to review this one, life has been complicated these days.

On yes, remember those nozzles filters? Here’s a little gift for the ones who read until the end.
Always remember that these can only be compared internally, the microphone was a calibrated Dayton Audio iMM-6, 95dB pink noise (not white, deal with it) was used for the 16384 points FFT, 60 seconds average, 1/24 Octave smoothing, the coupler was a little hose in which I inserted the in-ear nozzle with the smallest “starline” silicone tip I have at 3 to 4mm of the microphone head.
The measurements were made at night in a silent room.
For more information about the measuring setup click -> Here.
I need a better way to export the FFT because this resolution just doesn’t cut it.

The good & the ugly
Punchy bass, detailed mids and treble. On this price range I can’t find much to complain.
Solid build, many accessories and great cable.

These need a carrying case!
BGVP needs to rethink the plastic bag hell during unboxing.
The DMG needs a good source to sound excellent, any weak source (like a Sony L1) will struggle to drive them.
