Very comfortable
Really enjoyed wearing these! Had them on for like 3-7 hours and they were not hurtful the ears or my head. I have a quite small head and they still sat in place the whole time. I unfortunately had issues with the connection and the people I was talking to both during work meetings and gaming like cs go and so on was actually very disappointing.. the sound was amazing for music and podcasts, but definitely not for live talking. I had to take the sponge off the mic cause people could barely hear me. When I took it off, much better, but with connection fails..

Easy to use
My son has got these new JBL headphones.
They where easy to pare to his PlayStation, so he can play and talk with his friends in the game.
He says they’re comfortable to wear and has a nice sound, but his ears are sweating after longer use *laughing*
Overall he is satisfied with the headphones.
Also smart that you can use them after only 5 minutes of charging

Misleading - doesn't work effectively with Switch
Bought these today as one of the few devices that claims to work with the Switch. Unfortunately it only seems to work with the Switch when in docked mode and doesn't work wireless when the Switch is in handheld, which kind of defeats the purpose of them working with Switch. Will be retuning them tomorrow.

One of the best
I've had the joy of the JBL Quantum 350, and it's clearly one of the best headsets I've used. There is a great sound in them, so you do not miss important sounds when playing, for example, CS-GO. They also have a super good reproduction of music. They are easy to operate, definitely worth a purchase.

Clear sound and great design
I've been so lucky to test this great headset for a month and I am absolutely in love with it! When I opened the box, I thought it was rather clumsy, but that was put to shame when I put it on. The feeling of it around my ears was great. I wear glasses, and many headsets hurt after a while. Not these. I can almost forget that I'm wearing them. The sound is crystal clear and all information comes through - even when more than one person is talking. I would recommend this headset to anyone!

Great product. Read this if buying for Nintendo Switch.
Very good product. Sound is really good, microphone is detachable, feels very well made.
One minus point is that it’s advertised as being compatible with Nintendo Switch. It is only compatible with the TV docking station, the supplied USB-A dongle does not fit a Switch handset. I solved this by buying a USB-A female to USB-C adaptor cable separately. Not an elegant solution but it works. Important to hope if you are buying for a Switch.

Quality headset
I’ve always regarded JBL speakers as a premium product so I bought this headset not expecting the same since it’s a different design entirely. However I have been impressed by the sound quality and therefore rate this 5 star. Battery life is long lasting as well.

Great Sound - Instant connection
The JBL Quantum 350 Wireless are really impressive. They sound great and clean, and connect instantly. I tried them with work on teams where it delivered smoothly and connected them to Nintendo Switch docking. It was overall great.
