Chapter 1: Introduction to the JBL Quantum 610

When JBL unveiled a wide array of gaming headsets during the pandemic, I was taken aback by the scope of their collection. Even more surprising was the apparent success that prompted ongoing updates over the past couple of years. I previously reviewed the Quantum 300 and Quantum ONE, both of which I found enjoyable. More recently, I explored the Quantum 350, which remains a favorite of mine among wireless gaming headsets.

JBL has now introduced incremental updates to some of its earlier wireless models, designating a 10 to the model number while retaining the same price range. Enter the Quantum 610, which serves as a modern upgrade to the original Quantum 600 launched back in 2020. This latest model features an enhanced battery, a compact wireless dongle similar to that of the 350, and—well, I felt there should be a third point, but it seems I have left it hanging.

It's worth mentioning that JBL did not request or compensate me for this review.

The Quantum 610 is typically priced at $149.99, positioning it among the current contenders in the wireless gaming headset market. It supports USB connectivity for PC, PS5/4, and Nintendo Switch, along with a 3.5mm connection for those moments when your battery dies or when dealing with Microsoft’s frustrating Xbox audio licensing.

Battery performance is rated for 40 hours, which is easily achievable with the lights off. The USB-C port provides a decent charge time of 3 hours from completely drained. For those planning to use the headset primarily on a console, be aware that you'll need the Quantum Engine Software on PC to manage the lighting and other features.

Sound quality is where JBL truly shines, as is the case with most of their offerings and those from the Harman family. The JBL Quantum series is designed around the "Quantum Sound" signature, essentially the renowned Harman sound profile with an added bass emphasis.

Chapter 2: Sound Quality and Performance

The audio experience is outstanding, delivering crystal-clear sound that ranks among the best available in gaming headsets today. The treble and midrange are precise, complemented by a gentle bass boost. If the bass enhancement is not to your liking, you can adjust it using the Quantum Engine software on your PC. This software also unlocks features like QuantumSurround and DTS:X virtual surround sound. JBL's QuantumSurround remains one of my top choices for virtual surround on PC, and I hope they continue to refine it moving forward.

Comfort is adequate, featuring plush memory foam pads common to several other Quantum models and a well-padded headband. However, the clamping force is somewhat stronger than average, creating a tight seal against your head and around glasses. This design choice likely aids in audio performance and stability, but it can become uncomfortable after prolonged use, especially during the initial days of wearing them.

The construction is primarily plastic, which makes the strong clamping force surprising. While the frame and headband feel solid, the hinges for the ear cups and the attached boom microphone give off a cheap impression, especially considering the price point. A more robust design in these areas would have been preferable.

In terms of aesthetics, the headset maintains the bold, flashy appearance typical of other Quantum models, featuring customizable RGB lighting, though it’s not visible when worn. While it's a fun design, the permanently attached boom microphone is disappointing, especially since the less expensive Quantum 350 utilizes a detachable mic. One would expect that a refresh like this would embrace a detachable option.

Chapter 3: Microphone Performance

Mic performance is decent but suffers from overly sensitive levels and some compatibility quirks. The Quantum 610 only appears in select audio control settings in Windows 11, while it’s absent from others entirely. The fragmented audio selection systems in Windows have caused some confusion, but it’s odd to have a headset that doesn’t show up uniformly across them.

This leads to compatibility issues in certain games and occasionally with Steam chat, which sometimes struggles to connect with the microphone. This may be a personal issue with my setup, but it remains puzzling.

Chapter 4: Conclusion

Ultimately, the Quantum 610 is a solid update to a product that finds itself in a somewhat awkward position within JBL's lineup. The Quantum 350 is priced $50 lower and sacrifices wired connectivity but offers a sleeker design and a detachable mic. The advantages of the 350 likely outweigh the benefits of a longer battery life.

I've long believed that the Quantum series has too many model variations, and the 610 exemplifies this point. While it offers excellent sound quality and satisfactory build quality for the price, I would not recommend rushing to buy one unless it’s heavily discounted. The Quantum series is arguably the best-sounding range of gaming headsets available, but the same claim applies to the more affordable models, leaving the higher-end options needing to deliver more features. Unfortunately, the 610 does not quite meet this criterion, even though I don’t dislike it.
