Review : BGVP DM7 – Higher up


Design & Build Quality


Like the DM6, the BGVP DM7 is made of acrylic, like most CIEMs and modern IEMs. This material gives you the perfect blend of comfort and durability, even if models such as the FiiO FH5 keep the lead in term of sturdiness. Yet, at the end of the day, I’ll always prefer acrylic. It’s comfier and feels much more natural in the ear, at least in my opinion.

Compared to the DM6, there is not much difference and if you’re not familiar with BGVP I’m pretty sure you could mistake one for the other. NF-Audio and Noble keep the upper hand in term of build quality – their shells are much thicker – but that doesn’t mean the DM7 are bad in any way.

If you compare them to some of my CIEMs, sometimes five times more expensive, you’d be surprised of how much 3D Printing has improved. Yes, those are 3D Printed shells and they come in various colors, god bless technology.

If BGVP doesn’t appear to offer full CIEM solutions (yet), I’m pretty sure this can be made on-demand.

Build quality

Build quality is very good, but that was to be expected. 3D Printing is taking the lead and compared to the previous “hand-made” system, the risk for a bubble to appear is massively lowered.

Each drivers are perfectly sealed inside the shell. Even if you look very closely, you’d be surprised to see how clean the inner sides look: each driver is tightly fitted and cable management is so neat you’d be surprised to know there are six drivers.

The nozzle is the weaker point in my opinion. The BGVP DM7 doesn’t have a dust/earwax filter and it’s still lacking a small collar to block the tips and avoid any unwanted slips. Thankfully, the cleaning set is provided as a standard, so you should keep it with you at all times.

As I’ve said in my previous review, it’s great to see how the MMCX socket has become the new USB-C. It’s sturdy, easy to plug/unplug (most of the time), rotates on its own and it lowers the tension applied on the IEM socket.

If not the finest, the DM7 IEM is very impressive in terms of overall quality. Even more if you take the price into account.

Bundle and Comfort

Inside the box

The BGVP DM7 comes in the same plain, small, paper box just like we’ve seen last time, with everything nicely packaged inside.

Inside of the box you find:

  • the BGVP DM7
  • six pairs of silicon tips + comply foam
  • one 3.5mm MMCX cable, the 6N OCC+Silver 8 core straight-Shaped
  • a set to clean your DM6

Again, there is no pouch or case provided with the $299 IEM. If it’s your first purchase, be sure to get one separately as it’s very easy to break a set of earphones.

Additional accessories

The BGVP DM7 gets a nicer cable than the DM6, in my opinion. It’s an 8-core mixed copper/silver

Goods :

  • the straight shaped plug is much more easy to handle than the L-Shaped plug
  • sound-wise, it’s better than the classic copper cable with a little more definition in the upper-range
  • the braiding is top-notch and the Y separator is metallic
  • it doesn’t tangle

Bads :

  • nothing really

Each time we receive a new BGVP, the cable quality increases, which is no small feature.


I really enjoyed wearing the BGVP DM7. Once you’ve found the right tips, the semi-custom shape gives you a tight fit and a complete seal. If you’re used to classic IEMs, this is an improvement in every way and you should really try them before going to Custom IEMs.

To achieve the best design, BGVP cross-compared the database of ear physiology provided by Siemens. With tens of millions of eardrums, they ended up with an all-rounder design that should suit every listener.

The small curves adapt well and again I prefer the touch of acrylic, rather than aluminum. It just feels more natural to me and even more if you begin to sweat. On a daily basis, it’s clearly superior to the BGVP DMG and matches the DM6 in comfort.


Again, like the BGVP DM6, the DM7 offers excellent isolation. I take the train every week so a good seal can be mandatory, even more if you’re surrounded by (noisy) tourists.

I kept the medium-sized silicon tips, I’m not very fond of comply tips on my IEMs. Surprisingly, the tips do not fall off as often as the DM6’s, which is a real improvement.

All in all, this is a great IEM if you want to block unwanted noises out.

      This is a really great review and I’m grateful for the time and detail you put into it. I thought I’d float a question in hopes that you would respond. Of course “Which is better” questions are highly subjective but it seems our musical preferences seem to be similar. I’ve got a pair of SE535s that I have generally been happy with and have been contemplating and “upgrade” to the 835s, but then come along these DM7s. In my research I find several comparisons between the 835s and the Etymotic ER4XR …. so now I have decided I’m going to get a new set of IEMs and convert my 535s to BT …… If you could only have 1 IEM and your choice was the ER4XR, DM7 or SE835 which would it be? I think we’ve reached the place where price can no longer be considered an indicator of SQ (at least in this $300 to $800 range). Thanks

      Using the DM7 for a few days now. I love it more than the Andromedas.
