USB transmitter connects to your PC and sends audio wirelessly to headset
Wireless freedom and powerful sound
The JBL Quantum 600 headset is the least expensivewireless model inJBL's lineup of gaming headphones. Here's how it works: the Quantum 600 includes a wireless transmitter that connects that to a USB port on your PC, Mac, or PS4. From there, it will send sound wirelessly to the headset — with no lag between the video and audio.
When connected to a Windows PC, you can even get JBL's simulated 7.1 surround sound processing.
These headphones feature the same large 50mm drivers found in all of the other Quantum headsets. JBL's special headphone sound signature has been honed by years and years of research and exhaustive user testing. It's helped them develop a sound profile that's been proven to satisfy most listeners.
For gamers, of course, that means hard-hitting sound effects, but it also means directional cues that can help when competition gets fierce.
Hands-on with JBL's special software
The Windows PC app gave me control of everything from the surround sound to the pattern of the headset's multi-color LED lights.
These JBLs offers clear, powerful sound out of the box. But for an extra level of immersion into your games and videos — and a suite full of cool customization features — you'll want to download the QuantumENGINE software to your Windows PC.
JBL's advanced surround sound processing
The surround processing was effective with the right material.
The new season of the Netflix docuseriesFormula 1: Drive to Survive was a good fit for these headphones. All of the visceral racing action and tire changes came through with punch-to-the-gut impact. But then in lower-key moments, like an office meeting between a driver and race sponsor. Wireless or wired connection to your PC or console
In order take advantage of the QuantumENGINE software — including the surround sound processing — you'll need to connect to your Windows PC. You can do that either by connecting the USB-A wireless transmitter or the provided USB-C to USB-A adapter cable. You'll also use that cable to charge the headset and update the firmware.
Extra-thick memory foam padding on headband and earcups
The Quantum 600 headset also comes with a durable cable terminated by a 3.5mm miniplug for two-channel audio. So it will connect to the headphone jack at the bottom of your Xbox One or PS4 controller (and some third-party Nintendo Switch controllers). You should be able to make the same type of connection on the forthcoming Xbox Series X and PlayStation 5 controllers, based on the specs released by those companies.
Secure, well-cushioned fit
Gamers often end up wearing headphones for even longer stretches than we serious music listeners. So JBL added an thick layer of soft memory-foam padding to the Quantum 600's earcups and headband. These headphones do fit snugly, but that helps ensure that they stay properly in place while you move around.
One tip for all-day PC gamers: in the QuantumENGINE software suite, choose the EQ setting called "long session." It will smooth out some of the higher frequencies, so you don't get those harsh sounds that can grate on you over time.
Convenient communication and control
You'll find a game/chat balance dial on the left earcup. It gives you quick and easy control over the audio mix for multi-player games. Dial up the volume on crucial communication with teammates or tune out trash talk from annoying opponents. It is also certified for use with DISCORD, and compatible with other chat software including TeamSpeak.
Below that is a raised volume dial that's easy to find with your finger. Plus the attached directional microphone is tuned to pick up voices for clear-sounding chat. You can flip the boom arm up to quickly mute the mic.
