Good lightweight gaming headset for small heads
To preface, I have an extraordinarily small head. When I'm looking for headphones, I don't have the luxury of just picking the best quality or crispest sound or even best value... because most headphones do not size small enough to comfortably fit my head. I resort to earbuds in most situations, but I wanted a good mic'd headset for gaming/chatting online. I used to use a Turtlebeach wired headset, but when the mic broke, I thought I'd upgrade to a wireless set. Every wireless set I tried was way too bulky and heavy. Logitech's G935 fit me, but was so heavy it hurt my head and neck after a full day of wear. So I looked into bluetooth headphones. They have a built in microphone, not an arm and use bluetooth instead of a wireless dongle. I don't play many realtime competitive games, so I wasn't worried about delay. I figured I'd go big and got the Sennheiser PXC 550-II... Specifically because the biggest complaint on it was that it was too small for normal peoples' heads. I liked it at first, it's the first headset I could wear not on the smallest adjustment, but bluetooth does not play well with connecting to PCs. It worked great connected to my phone, but it would disconnect from Discord for no reason, would only play sound from one source (I couldn't hear game music and discord chat at the same time)... Also did I mention it was nearly $300? So I sent them back. I decided to give up on the quest for a wireless headset and look into good wired headsets. These were my choice. Their sound isn't top class, but they're also not $300, so I call that a win. I have no latency, my mic picks up sound clearly, they are lightweight and don't hurt my head, even when I wear them for nearly 10 hours straight (I use them for work and gaming), and best of all, they fit my dumb small head. On the smallest setting, of course, but they fit! My one gripe with them is that it has the "flip to mute" microphone and that doesn't always work. It's not a huge problem, but something to be aware of, especially if you're using it for work and think you're muted in a meeting... ... show more

Functionally Solid
Build quality feels sub-par. It appears to be entirely plastic and not particularly sturdy. They have little to no heft, which isn't entirely bad I suppose. These are quintessential closed-back headphones. The clamping force on your head is definitely stronger than average - could be too tight for people with bigger heads. Predictably the seal is very good which cancels out a lot of external noise. The earpads are quite thick and soft which saves the day comfort-wise from the heavy clamp. I'd probs give around a 4.5 on comfort overall. Sound quality is honestly not too shabby for $60 "gamer" headphones. The lower mids are a bit muddy but nothing close to the mess of my pretty-but-special Razer Kraken. Certainly not my preferred headphones for music but not overtly offensive. I didn't bother trying out the virtual 7.1 service yet because we really just play WoW, but I appreciate having the equalizer feature of the JBL software at my disposal. The microphone is what we're most impressed with: we have 2 PCs right next to each other and the one has a clicky mechanical keyboard that kept being picked up on the old neighboring headset making open mic a no-go. This headset picks up maybe 5% of the keystrokes tops which we're super pleased with. The flip to mute mic is a solid feature, though the click it makes to signify the transition is audible through the mic every time you mute w/ open mic on. The volume wheel placement kinda sucks. Its not intuitive to find nor to remember which way is up/down. Fiance doesn't have a left hand so for them the dial may as well not exist, lol. I'd certainly recommend these for anyone that can take care of them. I don't think they'd last a month of mild to moderate game rage or careless use, but I'm impressed by the both the sound and mic quality for the price point. ... show more

Comfy but hollow
I like the feel of these headphones and the audio quality is high enough for my liking (but I'm not audiophile). However, the big problem is the cord. Any rub on the cord travels up the headphones with no insulation to dampen the sound. It is extremely distracting the *wvimt wvimt* noise of the rub feels right in your ear. It makes the headphones feel cheap. Also, the mic feels like the adjustment will not perform well in the long haul, it just feels like it will snap at some point (something internal doesn't seem well made). They also don't do noise canceling despite the look, so you will still have some situational awareness depending on the volume you listen to. Bottomline, they are fine, I don't expect them to last long (not high quality), and if you move a lot when you are wearing them, these are not for you as the cord noise will be nearly insurmountably annoying. ... show more

Amazing sound and super comfortable!
I bought the JBL Quantum 300 and they completely exceeded my expectations. The sound is crystal clear, with powerful bass and a surround effect that makes you feel right in the middle of the game or movie. The microphone quality is excellent—my friends can hear me perfectly during calls and online meetings. They’re also very comfortable, even after hours of use. The ear cushions are soft, and the overall build feels premium. I love that they can be used both with a USB connection and a 3.5 mm jack, which makes them really versatile. The value for money is fantastic. Definitely a great purchase if you’re looking for headphones with great sound, comfort, and design. I 100% recommend them! ... show more

Bad Build Quality
For the Money I guess it is a good headset but some steelseries arctis 5 or 4's even are such a better alternative. After a little damage to the plastic frame connecting the headband to the ear cup where the wire is channeled through the right earcup totally broke, no audio at all. Mic is also REALLY quiet, or overly sensitive such as in zoom No one can hear me but in discord I'm fine. This issue doesn't derive from the mic sens. settings in those applications either its just the mic. In terms of comfort they're ok. From the looks of them the more expensive ones are obviously way more comfortable looking and these headphones must be worn loose-ish if you don't want a headache. Besides many problems I have the audio quality is great and great for gaming its just the build quality and mic I have many problems with. Unlikely to buy again. ... show more

Great for $30
Starting off simple: Pros Great sound quality and bass Nice usb or audio jack connection with adapter Good microphone quality with some tweaking Very comfortable High quality braided cords Cons Frame seems fragile and a little cheap First impressions of this headset are great. If you want great sound, spatial audio, and a good mic for budget $30 right now than this is a great option. The audio quality is as clear as AirPod pro 2s and it has more bass. The mic flipping up is very convenient. The only issue with the mic is that it picks up breathing even with the foam around it but honestly that shows how sensitive it is. Most games have mic level settings so this isn’t an issue and I didn’t mark these off at all for that. The plastic holding this together also seems a little fragile but with normal use and nothing crazy I think these will last a while. The cushions are also comfy so far and noise cancelling is decent. Overall great headset especially for the current price of $30 ... show more

Im on my 2nd pair i will say these sound pretty good compared to my old headset ( some Chinese trash) when they work. I am on my 2nd pair because, if you like to plug this thing into anything more than once in its life than it will become destroyed before long the angle that this is at is unnecessary and a big flaw in its design. if it were strong it would be no problem both pairs of these broke in the same way. My Chinese headset still works at least. Also the software at least at this time is trash it struggles to detect the headset even when the computer can see it but that was with the 1st one my 2nd one that problem was fixed, it doesn't matter because they don't work anymore and i dont think i will ever buy a jbl headset ever again and one of the main reasons i bought this was because it was jbl. Also that 80 dollars isn't easy to get so i am beyond disappointed. ... show more
