Huge Disappointment
I have been a huge fan of JBL for around 25-30 years and I was so excited when I found out they made gaming headsets because I have always had JBL audio equipment in my cars and they always sounded the best. Wow, was my bubble busted after I received this headset and a waste of $100 If you are thinking about getting a headset from JBL please don’t waste your money, get a Astro headset, they are light years ahead in quality.

AWESOME headphones
This is my first set of quality headphones in several years.
The fit is secure but not head squeezingly so. The ear pads are comfortable for long wear. There is a rotary switch to balance out chat vs. game volume along with a master volume rotary.
The USB-B to USB-C cord is about 10 feet long and there is also a 3.5mm jack cord that is about 5 feet. The headset can be connected USB-C to USB-C if you wish.
The microphone can rotate out of the way and will automatically mute when it reaches a certain spot. There is a small red light at the end of the mic to show when it is muted.
The software that comes with it is very easy to use, has a cool GUI and the 7.1 surround links to a youtube video to help you get it set up correctly.
I may buy an upgraded set in a year or so if this holds up.

Good but...
I bought about 3 months ago and the stiching already came apart on top of headset but I am getting them replaced so hopefully the second pair will last more that three months.. sound quality is okay except for some static at times not sure if I just got a bad pair or not but I really like JBL so hopefully the second pair are better than the first

I bought this headset for online school and within 3 months it was not working and I missed out on some great youtube videos and maybe it's just because I have a chromebook from 2013 or maybe it's because all of the jbl headphones I've ever bought have stopped working pretty fast so just don't buy it

Great Sound Quality
I have had these headphones for a month and have been impressed with the quality of sound as well as the clarity of the microphone. The ability to control the settings from the ear pieces was very useful. Would be perfect if it had a blutetooth connectivity option in order to be used with more gadgets.

Fab headphones!!!
Really quick to set up, no real need for instructions, you simply plug in and go.

They are very comfortable which is a bonus as I tend to wear them for hours when gaming. When I need a break, the headphones swivvle so they can rest easily around your shoulders and again this is very comfortable.

You can change the volume when gaming and also the volume when chatting which is something I really liked about this headset.

The bass and treble from the headphones is EXCELLENT and the microphone picks up sound extremely well. I have used these headphones many times when talking to my friends through discord.

Whilst they're not wireless which I would prefer, they are still really good as the braided cable is nice and long.

I could hear a faint white noise coming out of both earpieces whilst charging. This goes away as soon as you unplug the charger.

An excellent ‘all-rounder’ headset!
This headset has some amazing features - some of which are the high quality of the device, the easy set up and the great sound that this headset provides. I have been gaming for many years and over these years i have tried out numerous headsets, and of which many were low quality and ended up breaking after a month. However, this headset is of a high quality standard and my friends even noticed that my sound had improved! Overall, these headphones really are great and i would recommend them to fellow gamers.

Great headsets
Very satisfied with these headsets from JBL. Really good and clear audio quality and due to the cushioned ears, you get completely emerged in the sound. Tried with PC and Xbox and the quality is consistent on both - 3.5mm jack and USB connection. Good mic sound and volume. Lovely adaptation to various music styles and gaming regimes. Definitely worth buying if you are a moderate gamer who needs a comfortable headset with great audio quality for a decent price.
Also, can be used with PC and various online meeting platforms such as Skype, Zoom and GoToMeeting.
