Rated 5 out of 5 by from Excellent sound in all settings I have been using these headphones daily for 3 weeks. The quality is excellent of the overall materials and the sound quality is good, very clear with a good depth of bass and clear high pitch range. I use for watching streaming media and also use as telephone headset as working from home with my partner i need to block out ambient noise which these do really well. My ear is sometimes a little sore after 8 hours of use because they fit so well.

Rated 5 out of 5 by from These Are Exactly What I Need I use my JBL Quantum 50 daily connected to my Windows 10 PC. I have ALS and use my voice to operate and dictate to the computer. I enjoy the sound and the microphone picks up my voice well. I have also used these on my iPhone 6+. Siri picks up my voice cleanly. I have the dark version. To my eye, the actual orange is brighter and more prominent than represented in the photos.

Rated 3 out of 5 by from The mic needs adjustment I bought this after I ran over some reviews saying that this earphone will be good for gaming. It has a 3.5 mm jack which is compatible to laptop, but my friends have been complaining about hearing the playback from my browser like Netflix and YouTube. I sometimes can hear my echo as well, so it’s pretty useless when I use it for communication during the game. But it is comfortable when I plug it on my ear and the sound is not that bad. Since it’s not even $20 so I guess this is the price I have to pay.

Do they work for Xbox one wireless controllers? I would use Apple earbuds with my PDP controller but that’s the reason why I need these because those controllers always break on me. Would it work on a Series X Controller?

Asked by: noahnotthekid56
Our JBL Quantum 50 works with the Xbox One controllers, you can plug in the 3.5 aux cable from the Quantum 50 to it and get it working. If you need more help, please contact us here: https://bit.ly/3hH8oBR
