The tweeter is very directional. At smaller distances, it is necessary to put the speaker at the correct height or change the angle of the height converter.

Big worry and big shit. ...until you get it going, and then after a while anyway. back to sh. t.
High quality sound and performance.
Light parades for gaming comp.
Overall lousy application support on the manufacturer's side.
No USB Driver support for WINDOWS 11!
Connecting via USB throws away the sound of other output devices (headphones).
Overall, a big disappointment for me.
Speakers switching off after about 20 min solved by firmware update - JBL Quantum Duo V44 20220105

TLDR: not to buy, mediocre sound and a mile-long list of problems
Right off the bat the initial impression was bad, as the jbl app pretends it has no idea what it is. Cables short if you don't have the crate right on the table. It's a bit remedied by the sound, which is adequate, no crackling, bass ok, so average overall, no WOW effect. But over time, I found that for some unknown reason, they would turn off on their own, completely randomly. A short excursion to the internet and I discovered that I am not alone.
The sound itself is ok for pc work and some low action games, but for an FPS it's definitely not how it's presented. I mainly use them paired with my old iPod as a player. I expected much more from JBL.
decent sound
jbl soft can't recognize or find them
the aux cable is short
effects do not work with aux cable
the usb cable is short if you have the box off the table
they switch themselves off from nowhere even on USB playback and BT
BT button must be pressed each time to pair
as soon as the PC is switched on with the USB cable connected, the BT is disconnected
gaming maybe so for transport tycoon and sims, definitely not for playing FPS

the same as Ladislav of Letohrad (review 1.9.2021) and David of Hnevcevs (review 25.7.2021). I'm not going to rehash it again, for the money it's nothing but trouble! (although the sound, when they just decided to work fine, top notch)
