JBLQUANTUM300BLK

Solidly built and high-quality sounding closed-back over-ear gaming headphones with swivel ear cups, cable connection and a microphone with a drop-down headband. They can be connected using a 4-pin mini-Jack 3.5mm connector directly to a source device or to a bundled USB controller that supports JBL QuantumSURROUND surround sound virtualization technology. Compatible with any personal computers, laptops, Apple Mac platform, smartphones, tablets, game consoles (Xbox, Sony PlayStation, Nintendo Switch) and VR devices.

Thanks to the use of high-quality dynamic drivers with a large diameter diaphragm (50 mm), JBL Quantum 300 headphones are capable of creating detailed sound for game scenes of all popular genres. Especially good in multiplayer shooters and games with large open spaces. According to the manufacturer, they provide reproduction of the entire sound range (from 20 to 20,000 Hz). Also suitable for listening to any musical compositions. The ear pads, which are separated by delicate artificial leather, are filled with a special elastic foam material with a memory effect. With a firm yet gentle fit, the earcups conform to the shape of your head, providing passive noise isolation and comfort for extended gaming sessions.

Model overview based on user reviews  
The JBL Quantum 300 headphones are praised for their great sound quality and the ability to customize audio settings through software. However, users have consistently reported issues with the durability of the plastic, noting that the headphones tend to crack or break at the junction of the partition and ear pads after only a few months of use. Additionally, there are complaints about the short cable length unless using the supplied USB audio jack, and the design causing the headphones to slide off when tilting the head. Overall, while the sound performance is commendable, the product suffers from significant durability issues, making it a less reliable choice for long-term use.

I bought it for the New Year for 4000 thousand
Great sound. The software allows you to customize them for yourself
DISGUSTING PLASTIC. The headphones were not even 2 months old when they suddenly broke at the junction of the partition and the ear pads. + Constant problems with sound when communicating in discord

Better not. Model with jambs.

Everything would be fine if not for serious problems with the durability of the product.
The sound is really good. Even with the cheapest dedicated sound card they sound very clear and pleasant
The wire is short if you do not use the supplied USB audio jack. Due to the very flexible attachment of the cups to the headband, they tend to slide off the skull when the head is tilted forward/downward. The same fastening of the cups to the headband cracked and crumbled after about 2-3 months of careful use. The plastic is destroyed along the axis of the cup rotation sleeve. Most likely due to a very thin wall around the axis of rotation. Judging by the reviews on the Internet, this is far from an isolated case.
