BGVP DM7 – Review

BGVP DM7

| 6x Balanced Armature | 4-way crossover | 4x sound tubes |




🎧 We are reviewing the BGVP DM7, the newest 6-driver custom in-ear monitor from BGVP.

The BGVP DM7 features a 4-way crossover, 4 sound tubes and 6 balanced armature drivers per earpiece.

The specific balanced armature drivers models inside the BGVP DM7 are: Knowles SWFK-31376, Knowles ED-29689, Sonioi 33AP007, Knowles CI-22955 – the multi-balanced armature driver configuration is managed by the 4-way crossover (and the sound tubes), aiding to filter low, medium, medium high and treble frequencies to each specific driver.

The earpieces of the BGVP DM7 are 3D printed and built with medical grade acrylic fiber.

The BGVP DM7 is launched as fresh model from the brand following the previous BGVP DM6 and BGVP DMG and announced in a timely proximity with the BGVP ArtMagic V12 and BGVP DMS

.Despite the model naming that BGVP opted for, we find important to remind users that this model has 6 drivers per side and not 7 as it might seem from the name.

The cable is an MMCX, 8-core single crystal silver foil + single crystal copper with pleasant rubberized finish and a soft materials with no tangling issues and low microphonics. The cable of the DM7 is one of the most attractive bundled cables that we have seen so far, with a 2-colored cabling (dark silver + dark copper).

The initial availability of colors for the BGVP DM7 includes only the transparent with “frosted” back (the brand calls it BGVP DM7 white) like you see in our review but the brand intends to offer also these options:

Accessories & Packaging

The BGVP DM7 unboxing results in 10 pair of eartips (2 are foam tips), a 3.5mm cap, a brush and the very nice detachable cable.

The unit comes inside a rectangular box with a slim profile and a sliding, black cover – the size and style of the packaging is more or less inline with the BGVP DM6 and Fearless Audio S6 RUI.

B

Bass & Sub Bass

The BGVP DM7 bass is punchy and deep, yet it does not sound boomy nor too loose. Surely, the DM7 does not sound as bloated as many ultra-affordable multi-driver earphones, offering a more precise and balanced bass response that can still add important punch and depth.

Listeners looking for a full-sounding but non-drowning bass that can provide punch and fun when requested, yet remaining acceptably fast might find a good companion with the BGVP DM7.

If you are a frequent reader of ThePhonograph this “reminder” shouldn’t be necessary but remember that a higher score in this category does not necessarily mean a stronger and beefier bass response. The BGVP DM7 bass score is an example of this, as their high score obtained it is representing their somewhat tighter but fun bass.

Applying an EQ, very noticeable sub-bass deepening will be revealed but, honestly, it will be a pity to ruin their fairly-balanced bass response with an EQ.

Mids & Vocals

The BGVP DM7 have a warm midrange that, despite the tightish upper bass shown in our bass tests, can get slightly loose on specific mid/upper bass heavy tracks adding some congestion to their lower mids but without showing laid back male vocals.

Nonetheless it is fair to highlight that their mids are not particularly congested and by any means muffled; we would say that they are gentler and less analytical than other similarly priced and/or spec’ed in-ear monitors.

Higher mids are very well-tuned with the right amount of crispness, achieving a clean but not disturbing upper end.

Overall, we found the mid and upper midrange to be better achieved than their lower midrange.

There is not a huge margin for EQ retuning before their midrange introduce boxy issues but with an advanced EQ for fine tuning (adopting a cautious and conservative approach), the DM7 will show a vast improvement over their lower mids congestion without feeding harshness.

Highs & Treble

The BGVP DM7 are proficient in detail retrieval and showing a sufficiently bright personality with a less boosted end that could sound a bit darkish to some listeners used to treble-forward tuning or it can be greatly welcomed by listeners who prefer gentler highs/treble that do not sound muddy but that neither become clinical nor intolerably hot.

Moreover, sibilant peaks show precise peaks as to add a bit of spiciness to vocals without getting really sibilant.

Expect a highs and treble personality well-adapted for longer listening sessions than many other models on this price range and/or with this multi-balanced armature configuration that many times fall into an overly fatiguing and forward highs response.

As a reference, expect a highs tuning with a much smoother and less fatiguing peaks than the BGVP DM6 and Fearless Audio S6 RUI.

An EQ can add an important opening up and brightening of their highs that can be achieved with a fairly standard EQ.

Moreover, a very important addition of detail will be introduced without making their peaks too piercing nor sibilant.

Sound Leak

The sound leaking out of the BGVP DM7 is noticeably lower than on most average earphones.

Allowing a bigger margin to crank up the volume before becoming too hearable by nearby people.

Sound Isolation

The sound isolation provided by the BGVP DM7 is substantially more efficient than normal headphones.

A slight increment of volume in your listening sessions will allow them to reach an almost absolute isolation from the surroundings.

Comfort

The BGVP DM7 has a “fatter” and noticeably bigger size than both the BGVP DM6 and BGVP DMG but due to the resin construction material it offers ultra light weighted earpieces that are not as heavy as the DMG and more inline with the DM6.

The BGVP DM7 is a remarkably comfortable IEM to wear, mostly this is because of their overall light weight, in combination with the rounded edges and earpieces that have been designed after comparative analysis from Siemens ear canal databases from millions of ear canals.

Response to Equalization

The response to EQ of the BGVP DM7 showed important refinement and brightening of their highs and treble and removal of lower mids congestion, both without introducing too many issues.
