There is also a JBL logo emblazoned on the sides of each earcup, and if you are connecting them to your PC or console in wireless mode, you can set the logos to one of four RGB LED profiles. While I found the customization offered a bit lacking, and I prefer to have the lights off anyway as battery life is more important to me. So I would say that these should satisfy most casual RGB lovers, while falling short of those who want to be able to customize their glowing with more precision. Setting up the lighting requires running the JBL QuantumENGINE software in Windows. Thankfully, it seemed to remember my 'lighting off' setting while testing them with other devices.

Installing QuantumENGINE is also necessary to use the spatial sound features on offer. It's compatible with Windows Sonic and Dolby Atmos and DTS Headphone:X, if you already purchased those licenses from the Microsoft Store. But if not, these also include their own spatial sound engines. The first is DTS Headphone:X v2.0, and the second is JBL's own QuantumSURROUND. While I found their effects reasonably convincing, I'm generally not a huge fan of surround sound emulation and would likely rely on the game's natural audio most of the time.

While testing them, I found that the wireless range is truly excellent. I could walk almost anywhere in my house and it would get signal there. Only in the corners, or behind thick concrete, did it drop signal in my home. This is close to the best result I have seen so far, with only the Turtle Beach 600 Gen 2 MAX meeting or exceeding these results.

I was thrilled with their performance while connected via a 3.5mm audio cable. It also supports the microphone when connected this way. I used it for work, phone calls (my phone still has a 3.5mm jack), and various other gaming devices including the Steam Deck with wonderful results. I am really disappointed that lots of gaming headset manufacturers have gotten away from providing a 3.5mm connection options on their more recent headsets. I wish they would take a note from JBL here and continue to treat classic analog connections as first-class citizens. This was especially true for me, since the headset's wireless connection didn't work in Linux, while it works perfectly via an analog connection to my Linux-based desktop or laptop (or Steam Deck, for that matter). That being the case, I have probably used this headset more plugged in than not, and I haven't charged the headset at all since the first time, and the battery's still going strong at 50%.

The JBL Quantum 610 Wireless Gaming is a really solid gaming headset that gets the basics right, and the comfort even more right. The sound is a bit more bass-heavy than I prefer, but not so much that I couldn't enjoy them. It also helps that with some devices, a bassier profile may help; it's well known in audio circles that bass is perceived to get louder at a different rate than the rest of the audio spectrum, so if you listen at a lower volume, a bass boost is welcome. I feel like JBL has made an overall excellent product, though it has stiff competition in a very competitive market. I'm glad I got to test this one though, as it's a solid choice that a lot of people will really appreciate.
