Product Review: JBL Headphones I purchased a pair of JBL live 770 nc headphones just two weeks ago, and unfortunately, I am already experiencing problems with them. The headset has completely stopped working, and the Bluetooth is no longer pairing with my devices. I have tried multiple troubleshooting methods, but nothing has helped. What makes this even more frustrating is that I am currently out of the country (UAE), so I’m unsure how to proceed with a replacement or repair under warranty. I chose JBL based on its reputation for quality, but this experience has been disappointing. I hope JBL’s customer support can assist me with resolving this issue as soon as possible.

Made me say wow. jbl customer for life, because as you see in reviews they do their job. I still have two old ones beat up but still work. Long battery life, perfect connection, durable. Same sound quality and everything else from day one till the end which I am not even sure what will break them, they withstand lots of abuse. I have a cheap pair 30$ that were pretty good, just a cheap plastic design that broke when they fell. They still were usable though. The sound quality was cheaper but still ok, I didnt think to get new headphones right away. These were over the head style but on your ear pressed. I also had a more expensive $300 one that was cup style more comfy but the sound wasnt much better. Its the functionality that sold me over time. I cant imagine dealing with simple issues like connection or breaking with just careful use, poor sound, buzzing and list goes on. JBL doesnt ever have that. I did some research before getting these to find I love sub bass that shakes your ears which they delivered. It made me say wow. Ok so I tried listening to all music like rock, electric dance music and pop. Its more clear and better quality still but interestingly, if it doesnt have sub bass it doesnt bring out the best of these headphones 770nc. I got it just for the sub bass though so if you are into that, its worth the hype. Its in a lot of genres of rap. It performs beyond expectation with the functionaity and durability of jbl. It really does make me say wow. I doubt that skull candy or even dr dre beats sound that good, you should really try these out.

Excelente calidad de sonido. Cumple con lo que promete. Si esperas una cancelación de ruido por completo, estos audífonos no lo tienen, pero aún así la cancelación de ruido es bastante buena.

Calidad y precio.

Justo lo que esperaba de esta línea. La batería es lo que más me gustó, me dura una semana con un uso diario de más de 6 horas.

I was concerned whether they would fit over my ears but they fit very comfortably. Outside sounds are minimal when you want them to be with active noise cancellation, but can be adjusted through the app depending on how much you prefer to, or need to, hear. The downloadable app has plenty of adjustments you can make to the musical or vocal (voice podcasts for exemple) sounds you want to hear. Bass, mid range and treble notes were all great (I don't claim to be a sound expert, I just know what I like). They aren't particularly heavy, but I've never had over-ear headphones before so it's hard to judge. They can get a little warm if worn too long but I imagine that's true for any of these type of headphones. They are adjustable so should be comfortable for any size head to wear. I especially appreciate that I can plug them into my computer, which saves on battery usage, then I can switch to bluetooth if I want to travel. For the features and sound I was hoping for they turned out to be perfect! I was fortunate to buy these during Cyber Monday so the cost was very reasonable. They would be great even at full price.
