BGVP has had a couple successful In-Ear Monitors (IEM) come out recently with the V-shaped DMG and DM6. Both featured nice quality builds, accessories, and generally/mostly pleasant fun sound-signatures with respect to their prices at $150 and $200.

The company is following up the success of these two with a new model, the DM7, which will be released for pre-order exclusively on on May 6, 2019. This preview unit was sent to me by way of Linsoul.

Product Specs:
· Driving unit: six balanced armature units
· Sensitivity: ≥115dB SPL/MW
· Input impedance: 13.5 Ω
· Frequency response: 10 Hz-40 kHz
· The distortion rate: ≤0.5%(1 KHZ)
· Cable length: 1.2m ± 5%
· Weight: around5.3g
· Cable: Single crystal copper + single crystal copper silver foil wire.
· Standard equipment: vocal sleeve S/M/L, equalizing sleeve S/M/L, packing package X1, brush X1

The new DM7 sports a familiar shell design that sports 6 Balanced Armature (BA) drivers in each shell: a Knowles SWFK-31376, Knowles ED-29689, Sonion 33AP007 and Knowles CI-22955 with a 4-way cross-over.

The acrylic shell design is similar to that of the DM6 before it. So far, the only color I’ve seen is the white/pearl faceplate design with clear ear-side acrylic color. At this time, I do not know what other color options are available, but I imagine there will be the ability to customize it like the DM6 had. The white pearl color is pretty striking, and I really like how it looks. The shell is comfortable to wear with shallower tips for my ears. With lengthier tips, I had a very compressed sensation while wearing them, and it bothered me to wear over long periods of time – which is similar to the feeling I had wearing the BGVP DM7 and Fearless Audio S4, which have similar housings.

The new cable included is very attractive, with a copper/gray intertwined 8-core design. MMCX connectors are used again on this model, and the cable also has pre-formed hooks, which I personally prefer over memory wire. The cable plays nicely and has good ergonomics, and overall, is an improvement over the DMG and DM6 cables.

This review will be performed with a mixed playlist of rock, jazz, country, rap, and EDM. The sources used during playback on the DM7 were the RME ADI-2 DAC, the Astell & Kern SR15 A&Norma, and the Pioneer XDP-300R digital audio players. I used a combination of the included 3.5mm cable as well as a Kinboofi 2.5mm balanced cable for this review, as well as JVC SpiralDot tips.

The BGVP DM7 isn’t as similar to the BGVP DM6 as I thought it would given it’s naming convention and what not. Instead, the issues I personally had with the DM6 seem mostly addressed in the DM7. This model has a warm, smooth presentation that has good detail retrieval for this price range. It isn’t without flaws however, but let’s discuss it in more detail.

The bass region has good rumble in the songs the demand it. The intro of “Unfinished Sympathy” by Massive Attack has plenty of shake to it and transitions quickly. In Sigur Ros’ “Sven-g-englar”, the bass guitar has plenty of texture and detail, and has a very nice feel to it. It’s soft and subtle, but that’s expected in that song. The e-bow Jonsi uses on his electric guitar has plenty of sustained layering which seems to reproduced well on this IEM. In general, I found that the bass is well controlled and doesn’t exhibit much muddiness at all. It’s warm, and defined, but not bombastic.

The bass transition to mids is generally clean, though there are at times when the bass is slightly over-bearing over the male vocal range of the mids. I felt every 1970s Elton John track I listened to had Sir Elton further back in the recording than I am used to. Male voices in general, felt a little lean. Chris Stapleton, for example, doesn’t have gritty bite that I am used to in songs like “Broken Halos” and “Whiskey and You”. Part of this could partially be due to the dip in the mids before a rise in the upper mids, which puts female voices and guitars a little more forward than the lower mids.
I don’t find this very distracting from the overall sound though, and generally this helps create a little space. In the case of the DM7, it’s generally a more forward presentation, despite this little key difference, and is quite common tuning.

Whether it’s because I’ve been listening to Andromeda and Solaris lately or not, I found the DM7 to be missing a little upper end sparkle. When looking at the Frequency Response chart, it does appear that there’s big roll-off in the upper treble, and that would explain why some of that magic in the higher tier IEMs is missing. The DM6 also presented upper end boost, but generally had higher treble response resulting in what I found a harsher and strained experience.

The DM7 handles treble quite well despite missing the airy presentation of the aforementioned IEMs. The treble response is consistent and smooth. I never felt any sense of harsh peakiness, sibilance and anything other than a comforting presentation with good detail. One thing I did not like about the DM6 was the rise and peak at around 8KHz. The DM7, luckily, has a small rise at around 6.5KHz, and then drops off around 8KHz, and that alleviates the occasional sibilance I heard with the DM6, especially on poorer quality tracks and EDM music.

I found the DM7 to have a medium-to-wide soundstage while easily hearing instrument separation. I never found this IEM to sound congested as I occasionally did with the DM6 model before that. This may have to do with the more balanced sound signature versus the V-shaped sound signature of the DM6.


I went over this in the review quite a bit, but to recap, the DM7 is a more balanced tuning, but still leans on the warmer side. It does not have a big of a bass response or as high of a treble response as the DM6, but has a more mid-forward presentation than the DM6. The DM6 is an IEM that you want for a more fun listen or if you want to hear every little detail up front. The DM7 is a smoother and more relaxing listen in comparison.

Fearless S4:
The Fearless S4 comparison to the DM7 is pretty much exactly the same as what I wrote above for the DM6. At around the same price, I think it’s going to depend on preferences here. The S4, I found to be V-Shaped like the DM6, but with just slightly better instrument separation and detail retrieval, but not 100% sure it’s worth the extra $80 over the DM6. The DM7 is an easier recommendation over the S4 for most people given the tuning.

The following are just “from memory” comparisons, as I do not have them to compare side-by-side:

Audio Technica LS200iS:
More diffuse-field tuning than the DM7, which is closer to a Harman Tuning, but more mid-forward. Both are technically proficient, but DM7 would be my pick over it for better bass response, and better resolution. The LS200iS does extend treble more and provides more air.

Campfire Orion:
Orion is also a DF-like tuning, however has poor extension on both ends of the spectrum with rolled off sub-bass and rolled-off treble. While the mids are quite nice on the Orion, the DM7 offers a much better package overall in terms of sound quality at less the price.

The BGVP DM7 is my favorite BGVP product to date. They do have a quite a few more coming out in the near future and it’ll be interesting to see how the BGVP DMS sounds like. The early FR chart shows a similar sound signature with the extended treble to provide an airier presentation, which I criticized in this review on the DM7. We’ll have to wait and see though whether that FR is “real” and when it’ll be released.

That said though, the DM7 is a nice tuning and provides a clean, warm, inviting presentation that could easily be listened to for hours. I find it to be a warmer improved Moondrop Kanas Pro, which I reviewed with high acclaim earlier this year. Similarly, it is missing some treble spark, which I wished both of these had.

Despite that, I found the DM7 to be appealing to my tastes and an improvement over the DM6, DMG and other IEMs released recently in this price range that I have had a chance to audition.
Ok, understood in the review the comparison made was for similarly priced products, but with that said and price not an object, how does the DM7 compare to the Andromeda?
@Hi-Fi'er I think the Andromeda is a technically better iem, and has some nice sparkle and sizzle to it in the upper end of treble that the DM7 doesn’t have, but I prefer the tonality of the DM7 more. I like having a more pronounced upper midrange and lower treble, which the andromeda does not have. The Andromeda is a more warmer sounding iem in comparison. Andros are also much more source sensitive and dependent. The DM7 sounds more like the Solaris than andromeda, and I own the Solaris.
Thank you! That was what I wanted to know. Thank you!
Pros: Detailed, well-balanced sound - Comfort and Isolation - Great cable
Cons: Upper treble can be harsh every once in a while - No carrying case

Today we're checking out BGVPs newest flagship and follow up to the uber successful DM6, the DM7.

BGVP has really been on a bender lately with their releases. The DM6 and DMG were some high value, high performance products that looked and sounded fantastic, and were a huge step up from past products of theirs, at least those I've tried. The DM7 looks to take the brand even more upscale with a six balanced armature setup that combines drivers from renowned brands Knowles and Sonion, dampened by Knowles filters. Like the DM6, the shell is 3D printed using high precision German Envision TEC 3D printing equipment. None of that matters though if the tuning doesn't warrant the price.

Let's see if it does. Follow me!


Thanks to Lillian with Linsoul Audio for asking if I would like to review the DM7 and arranging a sample. The thoughts here are my own subjective opinions based on time listening to the DM7. They do not represent BGVP, Linsoul, Drop, or any other entity. At the time of writing the DM7 has not yet been released. That will happen on May 6th, 2019 at a cost of 299.00 USD and be available through Linsoul and Useful links below. (formerly Massdrop)

Personal Preferences:

I listen primarily to various EDM sub-genres (liquid drum and bass, breakbeat, drumstep, etc.), hip hop, and classic rock. My preferences for earphone tuning are quite relaxed and as such their is no one signature I look for. The HiFiMAN RE800, Brainwavz B400, and Massdrop x MeeAudio Planamic are examples of earphones with wildly varied signatures that are enjoyable for different reasons. I generally listen at very low volumes, so keep this in mind when perusing my thoughts on how an earphone sounds.


Mobile: Shanling M0 + Periodic Audio Nickel, ZiShan DSD

@home: ZiShan DSD or Asus FX53V + TEAC HA-501 desktop amp

While the DM7 is not a challenging earphone to drive, easily brought up to volume, it sounds somewhat dull when not amped or when run straight out of a less powerful DAP. Tossing in an amp makes it more dynamic and lively and is recommended.

  • Drivers: 6 balanced armatures (Knowles SWFK-31376 [super-tweeter], Knowles ED-29689 [tweeter], Sonion 33AP007 [mid-range] and Knowles CI-22955 [low range])
  • Sensitivity: 115 dB SPL/mW
  • Impedance: 13.5 ohms
  • Frequency Response: 10Hz-40Hz
  • Distortion: <0.5%
  • Channel Difference: <1dB
  • Rated Power: 7mW

Packaging and Accessories:

The DM7 arrives in packaging consistent with the DM6. The outer sheath is all black. On the front you find a Hi-Res Audio logo (not a sticker this time around), the usual branding and model info, as well as thin white outlines of the left and right earpieces. On the sides you have more branding and a sticker denoting the color of the product inside, which is white in the case of my sample. Flipping to the rear you find the specs, contact and location info for BGVP, and a frequency response graph. The graph is unfortunately not particularly useful because it is so small, and the line is red which really blends well into the black background. Why they didn't enlarge the graph and stick it in the 5”x3” void of nothingness above all the specs escapes me.

Sliding off the sheath reveals a wide but not very deep cardboard box with the BGVP logo front and centre. The rest is just plain cardboard. Lifting the lid you find the DM7's earpieces and most of the included tips set tightly within a foam cutout. Below is a compact BGVP branded cardboad box containing the cable and a couple other extras. In all you get:
  • DM7 earphones
  • 8-core mixed copper + silver plated copper MMCX cable
  • White, small bore, single flange silicone tips (s/m/l)
  • Orange core, medium bore, single flange silicone tips (s/m/l)
  • Black, wide bore, single flange silicone tips (s/m/l)
  • Foam tips (m)
  • Cleaning brush
  • Velcro cable tie
Overall a fairly basic unboxing experience, but with an awesome selection of ear tips. You should definitely find something to suit your needs here. The orange cored tips in particular are worth noting since they feature a Spintfit-like tilting system. Pretty cool stuff. The only thing I wish was included was a hard shell carrying case. There is plenty of room in the package for it, they're inexpensive, and the DM7 is necessarily an inexpensive product. Balanced armature drivers are generally on the delicate side, and with six of them per side the DM7 is not something you want loose, banging around inside a pocket or bag. Make sure you order a basic carrying case or have one on hand to protect your investment.

Build, Comfort, and Isolation:

The DM7 has a 3D printed resin shell made using German Envision TEC 3D printing equipment and medical grade resin. The sample here has a beautiful pearlescent white face plate with an integrated BGVP logo. Up top is a gold-plated MMCX port moulded flush with the body of the earphone. The rest of the shell is transparent allowing you to see the drivers, Knowles filters, and BGVP's neat soldering job within. The 4-way crossover is visible, but the specific workings are hidden since it is placed parallel to the face plate, on top of the drivers.

While the DM7 looks quite nice, once you take the tips off and check out the nozzle you can see it's a little rougher and less refined than the DM6 was. I understand why though as the DM6 was a more straightforward product with fewer fine details to work around. The DM7 has four sound tubes, three Knowles filters, and a fourth custom filter (looks like a piece of foam stuffed into one of the bores). All of this need accommodation in the same amount of space as the DM6's two much shorter sound tubes that end within the nozzle itself, and only one Knowles filter. The DM7 is also missing a nozzle lip, meaning some tips slide off with little to no effort. I experienced this with the preinstalled medium wide bore tips. Since the DM6 had a nozzle lip, its absence on the DM7 sticks out. Despite the noted nozzle concerns, the DM7 overall is very nicely built. The soft touch feel of a high quality resin is present, and everything fits together as it should. The driver layout inside is neat and tidy with a quality soldering job to back it up.

The 8 core mixed copper plus silver-plated copper MMCX cable is a gem. The 8 cores are intertwined in a somewhat loose braid giving it some desirable qualities. For one, it is very flexible acting more like a shoelace than a traditional cable in the way it moves and rests. Tangling is not an issue whatsoever, nor is the transmission of noise up the cable when it rubs against your clothes, or bumps into something. The attached hardware is quality stuff too. The metal straight plug is gold-plated and has a soft strain relief exiting out the top protecting the cable from bends. The compact metal y-split is only in place to hide where the 8 cores split of to 4 per ear piece. It lacks any form of strain relief, but this isn't a concern given the thickness of the cable. Above the y-split is a bead-like chin cinch that seems to be popular right now. It slides comfortably up and down the cable, and remains in place when in use. Heading up to the metal, colour coded MMCX plugs (red = right, clear = left) are preformed ear guides made from heat shrink. The curve of the guides is natural, comfortably carrying the cable up and around the ear. It is stiff enough to hold the cable in place while running, but not so stiff to cause discomfort. This is a great cable.

BGVP once again partnered with Siemen to use their ear image database to design the DM7. The resulting shape comes from averaging tens of millions of ears to come up with a shape that should be as universal as possible. A couple other companies have done this recently, such as Kinera with the H3 and IDUN, and in my experience it results in a very comfortable product. Few earphones using a different design philosophy conform to the outer ear quite like it. That said, while it certainly has it's benefits, it also results in a earphone that is larger than average so smaller eared folk won't be able to wear them. It also means those with an unusually shaped outer ear, or an outer ear than has been damaged in some way or another, will either not be able to wear the DM7 at all, or if they can it is with great difficulty. If you've got a “normal” outer ear, you're very likely to find the DM7 fits like it was meant to be there.

This ear filling design also results in a product that is highly isolating since there isn't any place for sound to bleed in. The shells are completely sealed forcing sound to bleed through the resin itself. As such, the DM7 makes for a great traveling companion on the bus and in other noise plentiful areas. Unlike the DM6, this sealed design does cause some back pressure when getting seal, though it's not as extreme as I've felt from other sealed designs. It can be mitigated during insertion by pulling up on your outer ear, and/or opening your mouth. These tactics let the pressure escape. Look weird, but they works.


Tips: Since people were worried about tips sliding off, I tried the DM7 with a fairly wide variety and this is what I found:
  • JVC wide bore - slide off and get stuck in the ear
  • Sony hybrid - core is too small and they slip off by themselves even before being used
  • Spintfit CP100 - secure
  • Final Type E - secure
  • RHA Dual Density - secure
  • KZ "Starline" - secure
  • Magaosi wide bore - secure
  • Ultimate Ears (from the UE600) - slide off and get stuck in the ear
  • Generic green single flange with orange core that you get with every budget iem and their mother - secure
Medium bore tips with a stiff core, like the Starlines and RHA, felt the most secure to me. Stock clone Spinfits too, but they use a very flexible silicone.

BGVP generally tunes their earphones to be much bassier than neutral. Prior to the DM7, that holds true of all their products I've heard, from the YSP04 to the DM6. The DM7 is the first to break this trend. While it still certainly isn't a neutral sounding earphone with lightly elevated bass and treble to keep things somewhat lively, everything is well-balanced.

Treble is reasonably even with mild peaks, including up until the brilliance region where there seems to be some additional emphasis. While this certainly helps with the perception of sparkle on cymbals, chimes, etc, and aids in the DM7's reasonably airy staging, it also results in those same instruments coming across somewhat harsh and unrefined at times. This was particularly noticeable when listening to King Crimson's live rendition of “Indiscipline”. Lower treble also feels slightly peaked which is evident comparing to the DM6. Clarity is quite good with a solid note definition. I also found these drivers fairly snappy, as is to be expected from balanced armature, with a rapid decay that helps keep notes from blending into each other. For the most part the treble is quite smooth, but it can occasionally overstep.

The mid-range is probably my favourite aspect of the DM7's presentation. It sits just behind the treble, less so the bass, in terms of emphasis. This gives vocals, guitars, and other instruments a strong presence on tracks where they are present, without them ever overstepping and becoming shouty, sibilant, or overly aggressive. I find this applicable regardless of whether we are talking about classic rock like Lynard Skynard's “Freebird” or modern pop like KDA's “POP/STARS”. Note weight is thin-leaning but I wouldn't classify it as lean. This helps highlight the pleasing clarity and detail available.

The low end of the DM7 is very mildly elevated with a mid-bass focus and good extension. Still, given it is not a strong presentation the DM7 comes across somewhat bass light compared to many earphones, an impression helped along by the lower bass roll off I'm hearing on Kavinski's “Solli”. That said, it can still answer the call when it comes time to thump, as evident running it through The Prodigy's 'The Day is My Enemy' which is a fairly bassy album. It also shows off the DM7's texturing and speed, both of which are quite good for an armature-based earphone. You won't find the DM7 tripping up on snappy, complicated bass lines or boring you with a one-note presentation.

The DM7 has a pretty satisfying sound stage that bests most of the armature-only earphones I've used to date. Depth is good but width is better, allowing the DM7 to reproduce sounds at a fair distance away from your head. I find this particularly helpful when playing games, like PUBG, Halo, or any other competitive game that benefits from accurate positioning. Layering and separation is also very good keeping the DM7 from sounded congested or flat at any time.

Select Comparisons:

BGVP DM6 (199.00 USD): While there are some similarities between the two, the DM7 is a notable improvement over the DM6. Treble on the DM7 is more emphasized with a bump to the lower treble that greatly improves resolution and clarity over the DM6. Extension and upper treble presence is more apparent thanks to the addition of a super-tweeter. The improvement in clarity moves through to the DM7's mid-range. Not only is clarity and detail improved over the DM6, but it is more forward eschewing the v-shaped sound of the DM6. Despite using the same driver, bass on the DM7 has been dialed down from the DM6, further aiding in it's more balanced presentation. Along with the extra presence, the DM6's bass provides more visceral feedback and kicks harder in the mid-bass. It is slower and less textured than what you get from the DM7. The DM7 has a much larger sound stage thanks to the improvements in the treble which. It sounds wider and deeper than the DM6 with more precise imaging and greatly improved layering and separation. I really didn't think the DM7 was that big of an improvement until I started listening to them back to back. It's pretty dramatic.

When it comes to build, I actually think the DM6 comes out slightly ahead. For the most part the overall shape and fit is the same. The DM6's printing for the nozzle is much cleaner looking, lacking cloudiness present in the DM7. The opening is also better formed and contains a nozzle lip, something the DM7 lacks. Now, in the DM7's defence, the nozzle design is much more complicated. It has four fully extended sound tubes versus only two in the DM6 which end well down into the nozzle. 3D printing can only be so neat once you're dealing with such small details. Both have high quality cables though I'll give the edge to the DM7's for it's improved flexibility and lower weight. It's a lot nicer to have draped around you ear for any period of time.

Fearless S6 Rui (389.00 USD): The DM7 and S6 Rui are similarly tuned 6 BA earphones having slightly warm, neutral-leaning signatures. The DM7 has more upper treble energy but sounds a tad more metallic in comparison. Resolution and detail is very similar with a slight edge going to the more refined S6 Rui. The DM7's mid-range is less forward with a leaner, slightly colder presentation than the S6 Rui's. Vocal clarity and overall detail is again very close with the edge going to the S6 Rui. One of biggest differences between the two is in the bass where the S6 Rui feels more full and dynamic. It has more sub-bass presence and additional punch in the mid-bass with better texturing to back it up, all without giving up speed and control. DM7 has a slightly larger and more open sound stage, particularly when it comes to the impression of width. Imaging is similarly stellar between the two with the S6 Rui having better layering and separation. I think the S6 Rui offers a more mature, refined sound and the better performer. To me it is worth the extra cost, but I suspect most would be more than content with the impressive performance offered by the DM7 for nearly 100 USD less.

The S6 Rui is a nigh flawlessly constructed acrylic earphone. Like the DM6 it only has two sound tubes, and like the DM7 they extend to the end of the nozzle. Due to this simpler design, the S6 Rui's nozzle is cleaner and more uniform that what you'll get out of the DM7. Both are missing nozzle lips to hold tips in place. Inside the S6 Rui, the driver, crossover layout, and associated wiring is cleaner and more organized, though the DM7's bright gold wiring looks pretty sweet. When it comes to cables, both are top tier and I'd happily use either. The DM7's uses a softer more flexible sheath while the S6 Rui has higher quality hardware (jack and y-split) and feels tougher and more durable. In terms of comfort, the DM7's slightly smaller, more shapely shell is a hint more comfortable for my ears.

Final Thoughts:

Overall I find the DM7 to be a very competent earphone with impressive technical ability. The mid-range is engaging, bass mildly emphasized and quite capable, and the treble clear with a tendency towards harshness every once in a blue moon. The sound stage is vast for an earphone of this style with great imaging, layering and separation. However, despite all of these positives, the sound of the DM7 doesn't grab me like others do. This might sound flaky, but it lacks emotion and comes across somewhat sterile. I'm not going to fault it for this since that is 100% a subjective impression, but reviews are a reflection and expression of one individual's experiences. I still like it and have no issues recommending it, it's just not something I see myself using on the regular.

That's no fault of the rest of the product since it is well-thought out. The construction quality is excellent minus some roughness around the nozzles. Comfort and ergonomics are good, and isolation is above average. The cable is flexible and comfortable around the ear (for me) with tight MMCX ports shared with Shure. They should last a long time. The accessory kit is nearly complete with quality tips and useful extras like a cleaning brush, the absence of a carrying case to protect the DM7 being the one notable exception.

The DM7 is clearly not an earphone BGVP put together last minute in an attempt to capitalize on the success of the DM6. If you've been holding off on trying something from the brand, now is the time to give it a go. This is the best earphone they've released to date and a strong competitor for the price.
