JBL Quantum 300

After working for some days it now will not work at all. There is no sound' On the computer screen it tells me to insert it into the USB which I have done and there is a blue light showing it is working. Is there anything I should do to persuade it to...

This was just what I was looking for to keep the noise levels down of my sons playing games using consoles! They seem to be very comfy and should last a long time! Sound quality is spot on - I tested them first 

I haven't found any yet!!

The ear piece is super comfortable and surrounds the whole ear so it doesn't press against the ear to cause any headaches. For quite bulky headphones, they do not feel as heavy as one would expect.

It is really bulky and the mouthpiece is a bit much, would rather it was smaller. The piece that increases the volume is a little bit hidden.

I relatively have a small head and generally get uncomfortable with these kinds of headphones and prefer in-ear headphone. However, this one was pretty comfortable for me. The adjustment worked perfectly. The sound was really nice and even when you...

I am not sure if it is possible but it would be perfect if it were more lightweight.

Very comfortable and adjust to make them a perfect fit . Easy to use and great sound and base from music and super clear mic and voice. I tested them on my PS4 my laptop and on my phone with the mic folded up out the way and were great on all The...

If the mic arm was thinner would make them easier to use just as headphones

The mic muting when it's up The comfort of the headphone itself The sound quality is brilliant, without being too harsh it keeps other sounds out The quality of the mic is brilliant - often get comments about how clear it is during meetings (as well as...

The usb wire is a bit long when I'm using the headset to talk on skype for meetings but good for gaming (so it's depending what you use it for).

The memory foam makes the over hear cups incredibly comfortable for long periods of use. Perfect for those long gaming sessions! The cable is nylon and stays tangle free. It's also a good length. It comes with an extension cable when using with PC that...

There isn't much to dislike here. If I was being really picky I would say that the foam on the end of the mic is easy to dislodge and it cane be easily lost.

Hello! Thanks for choosing me as one of your testers. I really like the design and I think it's very comfortable and with good sound quality in audio and also the mic. I really like as well the extra wire because sometimes I like to be on the sofa or...

I really don't think in any big improvement. Probably if I would say something but just a little thing, it's that when I use the long wire sometimes is in between my legs o around the chair and it's a little bit annoying. But in general I think is a...

For the price you are getting a fantastic product. Perfect for casual gamers. Loads of cushioning for comfort on those longer sessions. Design: I have a large head and there is plenty adjustment to fit my slab of head in but it also adjusts right down...

Mids can be a little muffled when listening to music. For example, Gregory Porter's voice sits a little deep in the mix compared to brass and bass. Braided cord is very thin! Not sure if it will stand the test of time. Also the cable is fixed into the...

The overall design is nice and the wearing comfort of this product is outstanding, the sound quality whilst gaming using the quantum software really is a game changer, I have tested this product on games that rely on good quality audio to play...

The only thing I'd say that needs improving is the usb audio adapter, quite often the adapter is plugged in and windows device manager can see it is and the volume control is up and default audio device set to the adapter but for some reason there no...
