Specifications

For the nit-picker and nerdy one here, I’m giving the specs and technical sheets. For all the other, you can just go to the next page to see how the Q2 performs.
Knowles Drivers + Proprietary DSP
At the heart of the BGVP Q2, we find two drivers from Knowles.
The Knowles 33518- RAD can be found in a lot of IEM, such as the FiiO FH1 for example. It covers the upper-mids and highs frequency providing “both a rich, yet delicate expression of music”. After listening to the FiiO FH1 I have to admit that, correctly tuned, it can achieve great lengths.
The Knowles 32873- RAF in the other hand, focuses its work on the low range of the spectrum. It’s a single full-range known for its “warm bass and excellent bandwidth”, which is what we need for an IEM. The frequency response exhibit a major boost around the 100Hz section, with low THD, so this should be an ideal combo with the 33518, if the crossover is correctly arranged.
To do that, BGVP implemented its own correction into the provided DSP. Like an active speaker, this can give astounding results, or poor performances depending of how well the sound engineers tuned it.
The 2-bores system is quite simple, but we’ll trust BGVP on that. Adding a dozen of armatures doesn’t always lead to a better sound, and the brand didn’t try to stack more than they could handle. Good choice.
3D Printed shell + Bluetooth 5.0
Bluetooth comes in its fifth version now. If I’d prefer an apt-X or LDAC support, Bluetooth 5.0 is still a major improvement compared to the old 3.0 we can sometimes see in cheap wireless IEMs.
The BGVP Q2 is compatible with Windows, Apple, and Android and supports A2DP, AVRCP, HFP, HSP, SPP, PBAB protocols. This means that each side will communicate with the other one, and you won’t have to stick the two IEM to your ears to make a connection, like my old Bragi Dash.
The shell is 3D Printed by the same company that produces the other models, such as the DM7 or DM6: Visiontech. Channel imbalance should not be more than 1dB and each ear only weight 5.0g, while embedding the Bluetooth system and a battery.
The batteries are rated at 50mAh and the charging case 350mAh, so roughly 7 charges to get around 26h of continuous play, or so they say.
All in all, it’s pretty good, and now it’s time to play !

You say that there is no cable included but you have a photo of it with the other included accessories. I have a Q2 as well and it came with the same black braided MMCX cable.

Is there anyplace else to purchase this besides Drop???

How do they perform when watching videos? Do you get any latency?
