Pro X 2 (left) and Pro X3.
The microphone is the biggest improvement by far. It went from an F to a B+.
The drivers are still 50 mm graphene, but the highs are much more prominent on the X3.
The battery life has gone up from 50 to 70 hours.
The Pro X3 gets access to a better software equalizer.
Connectivity
The connectivity options are the same as the Pro X 2. This means there is still no simultaneous 2.4 GHz + Bluetooth. The Astro A50 Gen 5 can do this, but it requires the Base Station to function, so it’s not really portable.
Aside from the mic, this is definitely the biggest improvement that Logitech could have made. Instead, you have to toggle between 2.4 GHz with the dongle or Bluetooth. You can also use this wired with the included 3.5 mm cable.
There's a niche functionality where you can play audio from a second source. If you have a phone or other media device with a 3.5 mm port, you can plug that into the dongle. While in 2.4 GHz mode, you'll hear audio from both your phone and whatever the dongle is plugged into.
As for compatibility, this works with PS5, PC, and Switch, but NOT Xbox unless you use it with the 3.5 mm cable.
Controls
Everything is on the left earcup:
Power switch. This has a sleep function if you leave it on. I don't know exactly what wakes it up, but I know that when I wake my computer from sleep, this wakes up from sleep also.
Volume wheel. This controls system volume on PC and Android.
Mic mute.
Bluetooth or 2.4 GHz (Lightspeed) dongle toggle.
While this cannot play audio from 2.4 GHz and Bluetooth at the same time, it can still be connected to your phone app and a console so you can make EQ adjustments without the PC app.
Headphone Audio Quality
Audio measurements taken with my miniDSP EARS (not industry standard).
Out the box, the Pro X3 is quite balanced. Pleather traps in far more bass than the cloth pads, so consider that before switching.
The Pro X3 is much crisper in the highs compared to the Pro X 2. I like the way the Pro X 2 sounds more in terms of tonality, but the overall detail and texture of the sound is pretty much the same.
The A50 has a much smoother curve, and when you actually listen to them, the A50 has far more thump and rumble in the bass than the Pro X3. It’s not as close as it looks on the graph.
I mostly played Battlefield REDSEC and Cyberpunk with the Pro X3. From a tactical perspective, I don't feel any of the headsets I mentioned really gains an advantage over the others.
They’re all closed back with graphene drivers and very responsive to EQ. So it really comes down to your tonal preferences.
A lot of the higher pitched sounds like that “shing” when you get a kill in Battlefield or the armor ticking sound can be pretty loud in the Pro X3. That said, they’re not nearly as harsh as treble cannons like the JBL Quantum 950 X.
When you hear footsteps on grass and rocks, they're definitely higher pitched and louder in those highs on the Pro X3, while they're slightly more boomy and realistic on the Pro X 2.
The A50 Gen 5 - which I like the most - gives footsteps legitimate bass. I don't think any of these approaches are inherently better, but I can definitely understand the appeal of the Pro X3 if you don't care about realism, and you only want as much information as you can get in games.
Microphone Audio Quality
The Pro X3 microphone is far better than the Pro X 2 which is the worst that I’ve ever heard. The sound isn’t quite as smooth as the A50 Gen 5, but it’s quite clear. I recommend using Blue VO!CE to contain the sibilance, add some body, and utilize the noise reduction filter.
Software (Logitech G Hub)
Just like the Pro X 2, this uses the Logitech G Hub app on PC. But now it also gets access to the phone app.
In G Hub, you can create multiple equalization presets for both the headphone and mic audio with a parametric EQ. You can use Blue VO!CE to make advanced adjustments and apply filters to the mic. Keep in mind that Blue VO!CE only works on desktop.
Comfort and Build Quality
The Pro X3 ties the previous version in both comfort and build. It’s extremely easy to mistake them for each other. The newer model is only a couple grams heavier at 341 grams without the mic and 353 with it.
The pleather pads feel about the same as before (soft, but not as much padding as the Cloud III). However, the new cloth pads are more snug and not as rough. The aluminum adjustable frame returns. The only complaint I have with the build is that it’s simply too heavy.
Verdict
The Logitech G Pro X3 is a big upgrade over the Pro X 2 in terms of the microphone, and it has sharper highs for treble enjoyers. However, everything else is pretty much the same.
I wouldn’t rush to buy it if you already have a Pro X2. I specifically recommend this for those who want a headset with a great microphone but are not interested in the Astro A50 Gen 5.
