Specialized gaming headphones from the popular American company JBL, positioned by the manufacturer in the middle price segment. Before us are full-size closed Over-Ear headphones with a comfortable headband, soft ear cushions with memory effect and a minimum weight (only 252 g), thanks to which the product sits perfectly on the head and is not felt even during prolonged computer battles.

At the heart of the JBL Quantum 350 headphones are 40mm dynamic drivers. Quantum Sound Signature technology delivers detailed and faithful reproduction of sounds across a range of frequencies, from soft footsteps to loud explosions. Proprietary software JBL QuantumEngine provides the ability to fine-tune the sound to the needs of the user. The manufacturer provides a removable microphone on the bow, which is necessary for communication in online gaming chats, but can be conveniently detached for periods when it is not needed. There are two options for connecting the device to the signal source: by wire, using the USB-A interface for this, or by radio. The battery life when using the headphones in wireless mode is 22 hours, and for a full charge they need only 2 hours.

great model, I really liked it
10 January 2022 
Super gaming headset. Excellent recognition of surround sound in shooters and other similar games, it’s difficult to put it into words, it needs to be heard. In addition to this, the music sounds great, and you can immediately feel the quality of JBL. In short, listen to something through them or play them and you will understand that this is an excellent device for your money, and then at home you will understand how convenient a wireless headset is in everyday life.
absence of wires
Elegant sound
New technologies
The headphones fully reveal their potential after installing the software and updating the headphones.
Also, you have to turn off the Quantum system when watching videos and listening to music, as it is more pleasant without it.

Comfortable, light, good sound. BUT it was all crossed out by an incomprehensible bug
6 August 2022 
I don't understand what is the reason
Price, convenience, microphone, software
It is not clear why, but in some games or applications, the sound simply lags (sound-silence-sound-silence jerkily)
