Great for video conferencing too
- June 24, 2020[This review was collected as part of a promotion.] Even though the headphones were created for the gamers I found they work great for video conferencing apps as well. The package comes with a 3.5mm jack and a 3.5mm to USB adapter so if your laptop does not come with an auxiliary jack you can still use the USB adapter. The left cup has a volume control and microphone. The cushions are comfortable but not too bulky. I tested the headphones on Zoom, Google Meet and Facebook Messenger and are all compatible. Now that we are allowed to work remote full time, these video conferencing tools have become so essential.

Best wired headphones I've ever had.
- March 13, 2025I bought it yesterday. It's so nice, I love it. I also installed JBL QuantumENGINE app on my PC, it's great. Good sound, looong cable, high quality microphone. USB adapter is very useful. My PC has two 3-pin connectors but headset has 4-pin connector, so USB adapter is my salvation.

Poor quality
- August 29, 2021Bought the headset a little over a year ago. There is a systemic problem with this JBL line of headphones where the swivel point for the hear pieces will crack (see photo). This happened a little over 4 months into its use. We sent them back for repairs and they were replaced. Same thing happened to the replacement headphones as well as the 200's that were also purchased. Since they were no longer under warranty I repaired them using epoxy and fibreglass, so they no longer swivel, but they will not fall apart any further now. Now at the end of a year with them the mini jack has cracked and it no longer works with the mic.

Very delicate
- March 21, 2021I bought this headset a few months ago and they were great. Zero complaints about the function, however they are sooo prone to breaking at the point where the ear pieces meet the headband. At these points the speakers swivel and through the attachment that swivels, there are cables running through. About a month in, I notices a couple pieces about the size of a grain of sand were missing. 2.5 months in while wearing the headset, a large piece popped off, landing on my keyboard, and the headphone was swinging free. At that point I could clearly see how overly prone to failure that point was. The plastic is very brittle, and surprisingly thin.

Good Gaming Headphone!
- June 25, 2020[This review was collected as part of a promotion.] I have been a fan of the JBL sound for decades and for my simple gaming and SKYPE, these fill a need at a reasonable price. The quality of sound is truly geared for gaming not-so-much for music. A touch bass heavy and mid-range voice boost. Attributes for gaming. The sound with music is OK, but there are better options if music is the primary purpose. Reasonably comfortable. Seals sound from the outside very well. No noticeable distortion. Competitive within the suggested price range. Recommended

Decent sound quality. Poor structure design.
- May 30, 2022Decent sound and mic quality. Was good when I first bought it but 2 months after purchase, the joints on the frame on both sides have broken. Won't even stay on my head anymore and because the wiring goes through the joint, the left side sound cuts out and mic intermittently doesn't work. JBL Don't put a rotating joint there, doesn't improve how it fits at all and makes a weak point for it to break at.

Amazing sounds and great mic
- June 23, 2020[This review was collected as part of a promotion.] I got this product from the JBL backstage program and have been needing a new headset for when I play. modern warfare and let me say this headset is a live saver. I can hear all my surroundings with no delay and my friends on the other side can hear me so clearly with no delay this headset is truly as good no actually its better then the competition like steel series and razor this line of headsets sets a whole new standard for them to compete with JBL did a truly amazing job with this and I hope to see more people buy and see the same results I have this is for sure going to be a 5 star from me and I am making all my friends buy a pair truly amazing.

Greatest Headset I Owned Until It Broke
- October 5, 2021Doing Work From home requires talking on the phone once in a while, and to be fair, this headset got a workout on a daily basis. Good stereo sound, and team mates could hear me very well! Much better than the free headset earplugs that come with a new cell phone. Trouble is, once too many times picking up to use it. The hinge on one of the ear cups just gave up, no use trying to tape it back together or anything. Again, to be fair, it got a lot of use over the last year and a half! I'll buy one again, and I wish I could keep using this one.

Poor build quality
- July 5, 2023When purchasing a pair of gaming headphones I was expecting something that can take some heavy use and is comfortable. The JBL headphones only fill one of those boxes. The cushioning for the ears and head are excellent but the durability was not up to par. After having this headset for just over a year, the swivel part that connects the speaker to the headrest broke. So the best solution was to tape it and hope for the best. It lasted another couple months before the right speaker stopped working. Other than the build quality, the microphone had crisp, clear audio and the speakers weren’t distorted and had great stereo sound. I did like that the cord was covered in a mesh.
No, I would not recommend this to a friend.
