Nowadays with a lot of Chi-fi manufacturers choosing to tune their IEMs towards the Harman Target curve, BGVP has instead tuned it more towards a neutral-balanced signature with a slight V. It sounds quite balanced across the spectrum. The quick dip in the mids cleans up a bit of the mud in songs which aren’t mastered well. For me, it is an easy listen and with the fit being quite comfortable, I enjoyed listening and testing it with my everyday rotation of IEMs.
To keep it simple, I wrote the sound analysis using large grey silicone ear tips which are provided as part of the accessories.
Bass is well balanced with good attack and decay. The sub-bass is nicely presented and can go low to the deep end of the human hearing spectrum. My test track for sub-bass is ‘Why so serious’ by Hans Zimmer & James Newton Howard. The soloed sub-bass section in the track (at around 3:26 mins) is well audible and has good rumble but does not jar my ears as boosted bass does sometimes. The mid-bass has a bit more authority than sub-bass in songs like Muse’s ‘Panic Station’ and Karnivool’s Goliath’. Even in songs like Porcupine Tree’s ‘Start of Something Good’, the bass has its nice own space in the center. Notes have good definition and clarity, helping me as a musician to easily identify every note. Both bass and kick drum play along quite well. Kicks are crystal clear with good presence in songs like Our Lady Peace’s ‘Do you like it’ as well as Linkin Park’s ‘Papercut’.
DM7 has a gradual slight dip in the mids, though lesser than the Harman Target curve. As a result, mids sound slightly fuller in comparison. They also sound very natural helping all instruments sound tonally accurate. I’m a big fan of drum tones and the snares sound lovely in tracks like I Am Giant’s Razor Wire Reality and Breaking Benjamin’s Diary of Jane. They have good attack, smack and body. Distortion guitars playing riffs are portrayed with good tonal accuracy and fullness. The resolution in the mids is very good which helps with instrument separation in heavily layered songs of bands like Porcupine Tree and Coldplay. Acoustic guitars sound natural too with good string definition and presence, while percussive instruments always sound full bodied.
The treble is relatively smooth and even though for some people it might not have the zing and sparkle of Harman tuned earphones, it makes for an easier and more neutral listen. Also, I’ve noticed a lot of multi-BA IEMs from the Chi-fi world having a peaky 3kHz region which in my opinion skews the tonality and is highly fatiguing. DM7 on the other hand is cool in that region and along with the comfortable fit, remains comfortable for long sessions.
The peak around 4-5kHz helps add presence to acoustic instruments and gives snares some nice stick attack. For me personally, it didn’t sound too intrusive. The peak around 6-7kHz adds sheen to the overall signature but luckily does not trigger any sibilance, at least not in any of my reference tracks.
Soundstage, Imaging and Separation.
DM7 has an above average soundstage which can be altered slightly using different ear tips provided in the package. IMO, the grey silicone ear tips have the best soundstage. Imaging is done well and separation is very good pertaining to the 6 drivers at work, especially for the asking price.
I reckon, a comparison between these two would interest most looking to buy a multi-BA IEM around $300-400.
Well, both are very similar when it comes to hardware specifications. They both use Knowles and Sonion drivers, are made up of resin and have semi-custom shells which are very comfortable to wear. DM7 comes with a better stock cable and a variety of ear tip options but S6Rui comes stock with a carry case which the DM7 doesn’t.
As for sound, S6Rui is tuned close to the Harman Target curve and as a result, right off the bat, you hear more treble and bass in comparison to DM7. The lower mid-range of S6Rui sounds fuller and richer whereas DM7’s sounds cleaner. In the upper mid-range, S6Rui has a higher peak around 3-4kHz which gives it extra sparkle whereas DM7 sounds more balanced in that region. The 7kHz peak of DM7 adds a bit of sheen whereas the S6Rui’s treble starts rolling off around there but doesn’t sound dark in any way. As for soundstage, S6Rui probably sounds a bit wider. Resolution and separation are on par. The winner out of the two is completely subjective according to one’s preferences. Both sound great while targeting slightly different segments of the crowd.
Shozy & NEO BG.
Shozy BG has a thinner character whereas BGVP DM7 sounds fuller in comparison. BG focuses on a clean and detail oriented character whereas DM7 focuses on a more balanced and richer character. Bass quantity and lower mids are quite similar. As for treble, BG has a peak around 8kHz which can make some tracks slightly sibilant. DM7’s treble is more even and balanced in comparison.
Tansio Mirai TSMR-3 Pro.
Since I like 3Pro in switch mode 100, I used that for the comparison.
DM7 and 3Pro’s bass quantity is quite similar. DM7 has cleaner lower mids as it has a dip around 500Hz which helps in cleaning up the muddy section. 3Pro’s higher mids are more prominent than DM7 owing to the 2-3kHz peak in the 3Pro. Overall DM7 sounds more balanced as the 3kHz peak in the 3Pro can be a bit peaky at times. Separation and resolution are slightly better in the DM7, probably owing to more drivers handling the duties.
DM7 is a very good proposition at $300. It has very good build quality, comes with ample accessories, and has a very good looking, sounding and feeling cable. Only thing missing is a nice case. It sounds pretty good and will impress more people than it will disappoint. I’m still amazed at how BGVP managed to price a 6 driver so handsomely, especially since they’re using all Knowles and Sonion balanced armatures. All in all, if your budget is strictly $300, give DM7 a shot. As for all guys worrying about the previous loose MMCX problem, be assured, I’ve tested it multiple times with a variety of cables to make sure that it has been resolved and the connection works flawlessly now.
