TL;DR version: Outstanding headset, great features, good battery life. Surround sound actually sounds like surround sound, not a cheap knock off. Audio clarity/quality is fantastic. However, I need to have my headset replaced due to the "stuck in sleep mode" issue because the battery won't charge anymore due to the software thinking the headset is powered off or in sleep mode. If you get this headset, make sure to get the 2 year GS replacement plan, just in case. However, I was an early adopter so the firmware in my headset could be all jacked up due to the changes. I'll be exchanging my headset at my local BB and will update my long version after I've had the new one for a few months.
The long version:
The surround sound, clarity, and features on this headset are awesome.... when it works. I'm getting the dreaded sleep issue. I got the headset when it first game out (I should've known better than to be a first adopter). I went from a set a Turtle Beach PX3s to this headset. For the positive things, there's a WORLD of difference in clarity and sound. The lowest are deep and mellow, the mids are full, and the highs are crisp and clear. The surround sound feature is fantastic. It's immersive and really feels like the sound is "in your head". The on board eq is very customizable and you can even program an eq for each game on your PC using the logitech software. It's easy to mute/unmute your mic simply by retracting the boom and flipping it up/storing it in the headset. I find this much easier than trying to hunt for the mute button by feel on the back of the left ear cup. Speaking of the ear cups, they are comfortable over long gaming sessions. Long Raids in WoW/LoTRo, hours of Rocket League, other steam games, this headset doesn't really get uncomfortable for me until the batteries start dying from being at a full charge. The ear cups rotate and fold flat so you can hang the headset around your neck instead of having to worry about the headset falling off your head while you are afk.
I read reviews before purchasing this headset and I tend to get 6-10 hours out of the headset with the lights set to cyan pulse. The color rotating setting makes the battery die faster and of course, if the effects lights are off you get an extra hour or two.
Now, to address my issues. I've had to reset the headset due to the sleep setting over ten times now. I got the 2 year geek squad replacement plan, so I'm going to go get a replacement tonight. I've reflashed the firmware on the headset several times using the Logitech approved method and using command line firmware upgrades. At first, the firmware flash fixed it and the new firmware has a feature to disable the sleep setting. However, my headset loses connectivity to the USB dongle if I go out of the house near the pool to take the dogs to the restroom (about 150 ft through several walls). The range is fairly good on the headset, as I generally don't lose it until I'm on the far side of the house or outside. So the range is fantastic. However, my best guess is it lost it's settings when I went out of range. Went I went back inside, it had the dreaded "stuck in sleep mode" issue again. Eventually, I gave up trying to factory reset it and just dealt with the headset only being a headset and a mic, no special features, no surround sound. Now, the eternal sleep mode on the software is keeping my headset from charging, so I have to have it constantly plugged in, which defeats the point of it being wireless.
***NOTE: I'm going to my local BB to have my headset replaced tonight and hopefully I'll have better luck with my next headset.
I had one of the original headsets before Logitech updated their firmware to add the feature to disable sleep mode and the firmware upgrade never really seemed to take effect well since my headset had already encountered the sleep issue. Also, yes, before anyone flames me, I did the factory reset with the battery removed to eliminate any settings staying in the memory on the headset.
I REALLY like the headset, the features really are fantastic for the price and with the price drop to $130ish recently, it's definitely a good buy. I bought it at the original $200 price and felt a little cheated when the USB dongle wouldn't work with my PS4. Well, it "worked", but the mic wouldn't work. For the mic to work you have to hardwire to the controller. Also, no, I don't primarily use this on my PS4, I use it on my PC, but I just wanted to see if it would work.
Anyways, I cannot truly say if I "recommend" this headset yet until I see if I just got a headset that got screwed up from the sleep mode/firmware issues. Hopefully the replacement will perform better. I'll update my review after I've had my new headset for a few months.
