Cons

  • Pure Stereo Mode (cable/dongle): Honestly this is a bit of a letdown soundwise. After hearing the lovely HyperX Cloud III S i hoped they would go for a similar tuning but they kept it more JBLish.. Which means Bass, Treble, Unnatural Mid...
  • Virtual Surround Mode: This is probably the most convincing Virtual Surround in Headphones i have ever heard. I prefer this over Atmos on the Airpods Max but it has tonal flaws which can largely be adjusted with the provided EQ from the...
  • One big improvement i would love in coming firmware updates: I used a Testfile for 7.1 Surround and all the channels sound very convincing except the 2 Rear speakers. They don't really appear to be coming from behind you, but the headset...
  • Calibration seems to be a bit funky at this moment, after Calibration the Bass is tamed and won't need any EQ but i have to lower 4khz by an excessive 9dB. So my guess is that it's still a bit buggy.
  • JBL seems to do false advertising for this Headset as they say in their Marketing Material and Website that the Quantum 950 is supposed to offer higher sampling rates when connecting with the cable, but i'm only offered 16bit/48khz.

Pure Stereo Mode (cable/dongle): Honestly this is a bit of a letdown soundwise. After hearing the lovely HyperX Cloud III S i hoped they would go for a similar tuning but they kept it more JBLish.. Which means Bass, Treble, Unnatural Mids :( The sound is basically a W shape with pronounced Bass, Treble and upper Mids. The upper mids show sibilance and harshness on some female vocals, so i guess there are peaks throughout the upper mids and treble. Overall the mids don't seem to be very balanced and natural.

Virtual Surround Mode: This is probably the most convincing Virtual Surround in Headphones i have ever heard. I prefer this over Atmos on the Airpods Max but it has tonal flaws which can largely be adjusted with the provided EQ from the Quantum App. Do not expect a super natural sounding emulation though, but for Movies, it does get close to a pretty convincing Cinema Sound System.

One big improvement i would love in coming firmware updates: I used a Testfile for 7.1 Surround and all the channels sound very convincing except the 2 Rear speakers. They don't really appear to be coming from behind you, but the headset can clearly do that when i turn my head and the whole soundstage shifts behind me. So it's capable but maybe needs some finetuning.
