BGVP DM7 IEM Review

August 10, 2021 5:58 pm

A little while ago I looked at the DM8 from a brand that was relatively new to me. Since then I’ve seen an outcrop of BGVP IEMs and accessories grow, gaining much interest in me. I though the DM8 was a great mid-tier IEM with impeccable separation and clarity. It made a great first impression on me, and I’ve been looking forward to checking out more from this brand ever since. I’ve gotten my hands on the even more affordable DM7, a $279 IEM seemingly from the same series as the DM8. Is the DM7 just as worth it?

In addition to these contents, BGVP also pack two more sets of rubber tips which is greatly appreciated.

Look and Feel

There are three color variations of the DM7, white, black, and blue. My unit was the blue variation, which I preferred aesthetically compared to the look of the others. I’m kind of a sucker for the more flashy colors on IEMs so I was a fan of the design here. The faceplate features some nice ocean-like art, coated in a glossy resin shell and a translucent style housing. It’s elevated by its construction of medical-grade PMMA acrylic fiber material. The fit is properly ergonomic and provides a fine level of comfort and security to your ears.

Design

The inside of the DM7 contains a surprisingly complex driver system for a more economical model. It features a six driver system that uses of Knowles and Sonion balanced armatures. Also included it its construction is a 4-way crossover system, which divides the signal into ultra-high, high, mid, and low end frequency channels.

Soundstage

While the DM7 never reaches the heights its soundstage of the DM8, it still retains a respectable amount of stage to showcase. There’s a good amount of width here, and although it doesn’t expand as much as I’d like it too, it’s enough to give the instruments enough space to position themselves clearly. The sound field exists in a more compact image, but still gives off the spatial aspects of the imaging. As far as the height goes, not much advantage is taken of the vertical headspace, but the horizontal space more than makes up for it. You won’t find the exceptional separation on display here as you’d hear on the DM8, but good attention is still paid to delivering clear layers.

Low End

A lot of the power possesses by the low end, exists mostly in the mid-bass. Here is where the bass gets its most considerable lift in tone, creating a much meatier response. It doesn’t lack in the sub-bass though. There’s enough rumble here to satisfy bass-heads, while providing clean textures for greater clarity. I didn’t find the frequencies as punctual as they might led on to be, and the timbre of them doesn’t feel like they operate with much space. It hardly brings down my engagement with the sound signature, but it does hurt the overall fidelity just a little bit.

Mids

Some of the bloat from the mid-bass makes its way into the tonality of the midrange. It doesn’t help that there’s some significant recession in the upper-mids, causing a bit of cloudiness in the frequency response. There’s a lot more space here than in the lows which much better separation, with a similar meaty response as the mid-bass. However, without that upper-mid presence, the timbre never feels as complete as it should.

Highs

Although the upper-mids are unfortunately missing from the frequency response, the DM7 tries to make up for it in the treble. There’s still some detail missing from the highs, but they mostly articulate themselves well. The tone is smooth and easily digestible for all types of listeners. Their tonality is very relaxed, but still defined enough to be noticed in the sound signature, making it one of the most natural aspects of the DM7’s timbre.

Summary

This doesn’t quite reach the heights of the DM8, but has some good qualities in its own right. If you enjoy a more forward mid-bass, you’ll get a lot out of this model. However, I wished there was a bit more fullness and space for the frequencies to play around with. It would have made for a much more clear and fulfilling sound signature. Overall, this is a solid IEM to add to BGVP’s growing library of affordable earphones.
