Everything seemed good until we open them up and realized the left speaker does not work

Sounds like trash quality is poor don’t buy get beats

So far I’m enjoying not having to rely on my Sony headphones connected to my stereo system with a cord. The JBL 770 headphones work great with my Sirius app on my phone. I hope I can use them on my next airline flight.

[This review was collected as part of a promotion.] I so dig my new TUNE 770nc headphones. I used them on a bike ride right after I received them and they are so awesome (well they are JBL, THE BEST !!!) I then used them to call some friends and they could not believe I was on headphones .. I had to let them know they are the new JBL TUNE 770nc

[This review was collected as part of a promotion.] Very comfortable. Noise canceling is decent. It probably starts kicking in at 3/4’s volume, then outside noise starts being difficult to hear. In this setting, at max volume, it is impossible to hear outside noise. I had my television at a seven volume. The toggle buttons take awhile to get used to. These are probably the best headphones I’ve had from any company. It did take a reset and a 10-30 seconds to find my iPad and connect. It is faster to find and connect on an iPhone. No irritation with ears and hair when headset is on. Very soft and secure. Bass is pretty good on Drake songs from Honestly Nevermind and Justin Bieber’s Right Here.

[This review was collected as part of a promotion.] The sound quality is good, as always. Good treble with punchy bass, especially for the price point. Ambient aware is incredibly useful with the "noise sensing" mics, but can be annoying when anything brushes against them like a hoodie. The ear pads seem smaller than some of their other headphones, sitting on my ears more than other ones that I wear. This may be a good thing for people with smaller ears and may just be my opinion. I love the headphones, they just aren't my favorite.

I've had this Tune 770 for a few weeks. It works very well. I listen to audiobooks. Everything comes through clearly. Sound is cancelled quite well. When I listen to music I get great bass and treble. The only thing is, I had a more expensive set of headphones that I lost. It took me a while to figure out how to turn this one on after the other system which was much more direct and intuitive. The graphic directions didn't help me.

Got these to replace a cheaper pair with a lesser battery. The idea was to use them at work. The battery can last the whole workday and them some. Sound quality is outstanding. But now I get frustrated when I hear the same songs through other devices and my favorite parts aren't even noticable. The battery life is so good that I have taken to listening at home when I'm putting away laundry or making dinner. Great way to ignore bickering children.

[This review was collected as part of a promotion.] Alright, let's ditch the boring tech jargon and get real about these JBL Tune 770NCs. Buckle up, because here comes the straight-up scoop from a fellow music lover: The Good Stuff: Battery life like a champ: These bad boys go on and on like a never-ending playlist. 50 hours with ANC? I dare you to listen to that many podcasts in a row! Plus, a quick 5-minute charge gives you 3 hours more juice, perfect for when you're caught short before heading out. Comfy like your favorite hoodie: Seriously, these hug your ears like a well-worn beanie. The padding is plush, the headband's adjustable, and even after hours of rocking out, your noggin won't feel like it's been in a vice. Peace out, noise pollution: The ANC does a solid job of silencing the outside world. Airplane rumble? Gone. Chatty coworkers? Vanished. You're in your own sonic sanctuary, baby. The Not-So-Good Stuff: Sound ain't no audiophile dream: Don't expect studio-quality precision here. The bass can get a bit boomy, and the overall sound isn't the crispiest. But hey, for everyday listening and pumping yourself up at the gym, they do the job just fine. Plastic fantastic (not in a good way): The build quality leans towards the "budget-friendly" side. Sure, they're not gonna shatter if you drop them, but they don't exactly scream "luxury." Sweat happens: These aren't exactly waterproof, so intense workouts might leave you with some soggy ear cups. Stick to light cardio and they'll be your gym buddy, but leave marathons for the truly sweatproof models. The Verdict: Look, the JBL Tune 770NCs aren't perfect, but they're a solid pair of headphones. They're comfy, have killer battery life, and do a decent job of silencing the world. If you're looking for a way to tune out the chaos and immerse yourself in your music, these are definitely worth checking out. Just don't expect mind-blowing audiophile sound or Olympic-level sweat resistance. Ultimately, the bass on these headphones is a double-edged sword. It's definitely their strong suit, but it might be a bit too much for some listeners. The key is to try them out yourself and see if they strike the right balance for you. If you crave that floor-shaking rumble, you'll be grinning from ear to ear. But if you prefer a more nuanced sound experience, you might want to keep searching.

[This review was collected as part of a promotion.] I didn't think I was going to like these as much as I did but they sounded pretty sweet. I love how the low end is and how crisp the highs and other elements sounded with these. I did feel they were pretty tight at first but within minutes of listening to these it didn't bother me. I do like the multi connection feature a lot. The NC is just right and doesn't bother me like my airpods do. So that was a nice touch for sure. The sound overall I felt was nice and balanced. I do wish I could EQ the low end to my liking though but that's ok. I listened to dance and metal on these and both genres sounded pretty sweet. The build quality feels solid and not cheap at all. The charge holds up as well. This is my first of headphones like these and I'm satisfied.
