I received a review unit from Linsoul. I've only spent a few hours with them so far but I do like them.
The DMS is the latest from BGVP. I rank this one above the DMG and DM6 for my personal tastes and just below the DM7. Sound-wise, these are V-shaped but balanced much better than the DMG and DM6, as their bass is a little more subdued, the mids are slightly more elevated, and treble isn't sharp or harsh. The bonus on the DM7 is that these extend treble in the upper range more than the more premium model. They don't resolve details as well as the DM6 or DM7 though, which is why these are $150 and not $200 and $300.
