#Bgvp dmg review drivers
The DMS uses an internal support designed from the ground up to hold the drivers in perfect alignment to reduce phase issues and reflections/resonance (This part is still 3d printed I am told).
#Bgvp dmg review driver
A 4 way crossover is used giving the two mid driver packages two separate tunings, the other two branches of the cross are for the dynamic and the SWFK respectively.

handling the lows, two DEK-60318 packages for mids (for argument sake, the DEK is a dual package so this is 4 drivers) and a Knowles SWFK-31736 package (again dual drivers in one frame) for highs.

The DMS is another entry into the greater driver race with a 10mm dynamic driver with gold plated diaphragm for additional rigidity. Comfort was quite good and I had no issue with long listening sessions. Nozzles have a distinct forward and upward rake to allow for deeper seating in the ear but isolation is limited due to shape and venting.

Its hard to picture but easy to see if you look at the pictures below. The filters screw onto the shell rather than into it which seems to be a much more common arrangement. Nozzles are separate components and are threaded onto the inner shell in a unique manner. An additional pin-hole vent sits at the mid-point of the underside of the shell. Unlike a lot of others, these are functional vents. The Face-plate has 3 large vents shaped to match the BGVP logo. These have a true face-plate and inner shell design with all of the electronics sitting in the inner shell. I consider the DMS to be medium sized so those with the smallest ears may have fit issues, but most should not. This is probably partially due to the size and shape and partially due to the weight reduction the large front vents accomplish.
#Bgvp dmg review full
Despite being a full metal shell, the DMS is fairly lightweight. Blue is still an option for those wanting something a bit more lively than the black shown in this review. While I have seen some claims that the original DMS was 3d printed using magnesium alloy (as was the DMG), current production DMS are being made using a machined aluminum shell (per BGVP) and are no longer available in silver. Unfortunately, putting the extra filters in that pocket makes for a cramped fit for the earpieces so one needs to select a filter and leave the others at home to keep from over-stuffing the case. The case has enough room for the earpieces and cable with a side pocket for spare tips. Filters come in their own small plastic clam-shell for storage while not in use which is a nice touch as they are very small and easily lost if not kept in some sort of locking container. The kit now consists of the earpieces, mmcx cable and Velcro tie, 9 set of silicone tips in 3 different styles (gray, black, and blue), a single set of foam tips, a shirt clip, the filters (3 sets), and the soft case. Lifting the cover reveals the earpieces and a variety of tips nestled in foam at top, and a soft case with the remaining items inside it in the lower portion. Once removed, the box itself is tan with a large BGVP logo centered on the front. Packaging starts with a black slipcover with the line drawing of the iem, model, and BGVP logo on the face and the specs on the reverse. If you have an interest in BGVP products, check out their Facebook page, or AliExpress store. BGVP offered a discount for the purchase, but no other incentives or remuneration were provided for this review.

For that reason, I have dubbed this the V2. I have owned the DMS previously (borrowed by my children) and was surprised to see this new one has removable filters that the original did not. Disclaimer: I purchased the BGVP DMS at a reduced price along with the Zero for purposes of review.
