My friends, as someone who enjoys spending 12 hours or more on the computer with non-stop gaming, these headphones are not suitable for that because the battery simply doesn't last. After 15 hours of continuous gaming and microphone use, with the LED lights turned off, the battery dies.

- As for MUSIC, they surpass many headphones that cost a lot more. Very good bass and perfect clarity in the treble. Absolute detail in all frequencies.
- As for VOLUME, it is not very satisfying if you are someone who likes to blast the sound (this can be corrected to some extent with programs like FxSound).
- As for the BATTERY, I believe there are few of us who actually play for so many hours, so you won't have much of an issue UNLESS you are the type of person who constantly wants the LED lights on, in which case good luck with it lasting every 8-9 hours.
- As for GAMING, I found that the surround sound offered by the company is the best, it just takes a little while for the ear to get used to it. The sounds are perfect! The details are perfect in FPS games, you will know exactly the direction and distance of the sound.
- As for COMFORT, unfortunately for us with headphones, they are NOT comfortable at all, they start to hurt after a couple of hours.

The jack is a 3.5mm stereo with microphone (it has three rings), which means it separates right-left-microphone-ground.
This means that it works fully on both mobile phones and computers with sound cards that accept a microphone and stereo headphones with just one jack.
If the battery runs out and you don't have a sound card, it doesn't matter, you can still use it as headphones in the speaker port in the front or back.

I have had these headphones for 3 months and I wouldn't buy them again just because I wear glasses. But I love them because I have never heard such music, not even from speakers, and I compare them to a €5000 external audio system that I have.

JBL warranty gentlemen! Full sound, quality construction, sensitive microphone, overall beautiful package! I already have 5-6 JBL headphones. Along with MARSHALL, at the top for years! It doesn't directly connect to BT on a mobile phone. However, with an adapter from type-C to type-A (female), you can connect the stick and make them wireless headphones for your phone immediately. The "trick" will just stand out a bit...!!! They are worth it! I didn't find big differences from the Quantum 800, that's why I preferred them. Purchase at €86. The 800 are around €185...

I have had the headphones for about 5 months, they are excellent headphones with very good noise isolation, wired with a high-quality cable included in the package, and wireless with a USB stick. When you connect the headphones to your computer, you will need to download the JBL Quantum Engine application, which offers many options regarding the sound, such as where it comes from, in what format, and you can create your own sound according to your preferences. They are of high quality for gaming and more, but they can become tiring during prolonged use due to their relative weight, although they have cushions everywhere that will not cause discomfort. The microphone is decent and works on mobile devices as well. The headphones have a very good battery that lasts quite a while, and even if the battery runs out, they can reach 100% in about 45 minutes to 1 hour, in proportion to the 14 hours they last. Overall, they are quite good headphones and, in my humble opinion, a level above the Razer Kraken. I hope I helped. P.S. Beautiful packaging
