[Closed-Back] [This review was collected as part of a promotion.] Having an adaptive noise cancelling pair of headphones is a game changer. They automatically adjust noise cancelling based on what's going on around you and also allow the user to adjust how much noise cancelling is needed. This makes listening to music and podcasts so much better. The sound quality is top tier and the headphones get very loud, the bass is good as well. I love the automatic pause/resume whenever the headphones are removed or put back on. This prevents having to fumble about for a phone or buttons on the headphones. Overall I'd rate the JBL Live 670nc a 9/10 but only because my ears got a bit uncomfortable after about 1.5 hours of use. This is due to the nature of on-ear headphones vs over-ear, it's a personal preference.

[Yes] [This review was collected as part of a promotion.] The JBL Live 670NC are small/compact and have good sound overall. Out of the box they are simple to set up and thanks to the app I can customize the audio to my liking. Thanks to the JBL Headphones app I was able to take a Hearing Test to output the best sound based on my hearing level and it will customize the Lows/Mids/Highs based on the results. The audio lacks a bit and does not sound as full, but the bass is very punchy. Call audio is very good, had zero issues with callers not being able to hear me and the call was very clear on both ends. The Noice Canceling is also very good. Exterior noice is muffled and it lets me enjoy my music without issues. A fun feature is the tap function on the right ear cup that lets me control the music instead of shuffling around to locate a button to press and control the audio, a quick tap of the ear cup is a lot faster. Siri also works well with the headphones. Using them for the gym was very comfortable and the clamp force around the head is just enough to keep them from falling. Overall I'm happy with the JBL 670NC both in sound quality and the features it includes.

[Dynamic] [This review was collected as part of a promotion.] Whether you're a music enthusiast, a frequent traveler, or someone who simply values quality audio, these headphones JBL Live 670NC sure to impress. My everyday go to headphones work amazingly. Highly recommended!

[Yes] [This review was collected as part of a promotion.] The JBL live 670NC with noise canceling delivers a crisp sound with a boomy base. They connect very quickly via my android phone and are very, very comfortable. The ear cups do not hurt my ears at all. The sound is balanced with lots of base, but you can use the JBL headphones app for more customization and versatility. You can customize your Equalizer or use use the preset Equalizers on the app. Voice assistance can be customized to Google assistant or Amazon Alexa. The noise cancelation works very well, and you can use the ambient aware. The buttons on the side of the earcups are very easy to reach at your fingertips. The headphones tell you when the power is off or on or when the features are on with a female voice. The headphones are truly amazing and compact. They have spatial sound too for that inmersive sound. The battery is very long lasting, while playing music for up to 65 hours.The included carry bag is very nice with the JBL logo. Overall, I love the JBL Live670NC balanced sounds and how compact it is. JBL has created another compact headphone masterpiece with lots of features. You will not be disappointed with the size and sound of the size of the JBL live 670NC.

[USB-C] [This review was collected as part of a promotion.] I’ve always wanted a pair of on ear headphones that are comfortable and won’t irritate my ears as I have many piercings. These headphones are made with very good quality. I like the detail that was put into it. The top of the headphones (band part) have a nice soft fabric and the ear part is made with a soft cushion. I mainly used them while working out. They stayed in place while I was doing jump squats and all other activities and they did not slip off despite the sweat. They were easy to clean and I put them back in the protective pouch after. They sound phenomenal and with a quick tap on the side I can pause my music. They are great with noise cancelling so I can really focus but also have an ambient aware setting so I can be aware of my surroundings if I’m walking in the street. I took a few phone calls and I hear the voices very clean and the other person says I sound very clear as well, so the microphone picks up very well. One charge lasts so long so the convenience of not having to constantly charging them is great. The style is nice and sleek, not bulky all. These are great for anyone honesty, anyone can enjoy these as much as I do. I was be taking these with me on my next trip.

[Lithium-Ion] [This review was collected as part of a promotion.] After using these headphones for the past week, I must say that I am pleasantly happy with this product. Here are a few key points for those who are looking to purchase.

Long lasting battery: Over the past week, listening to music and connecting to my computer for work meetings, I have yet to charge it. It automatically turns off when not in use and connects when needed. So this allows for a longer time of use.

Comfort: It is very light, I could hardly tell it was on my head. For someone who is staring at 5 other over the ear headphones, this one is my go to now.

Quick connection: If I am on my computer, once I turn it on, it connects automatically now. When I first got it, my tablet (apple), my phone(apple), and my computer (windows) all recognized it and connected without failure.

Buttons: The buttons are displaced perfectly on this set. I didn't even have to look at the instructions, it just works!

Sound: Crisp and clear for music. Not overly bass heavy, which is nice when comparing them to my Beats. Clear and no background noise for phone calls. I asked many people and made phone calls and everyone stated that they could hear me and I could hear them perfectly.

Nice Job JBL!!

[2] [This review was collected as part of a promotion.] The JBL LIVE 670nc are well made and fit very snugly. They fit so snugly that they start to hurt behind my ears with my glasses on after about 20 mins or so. I have to adjust my glasses to fit above my ears to alleviate this. The sound quality really good to me. The vocals are clear and the spatial sound allowed me to hear things that I’ve never heard in songs that I’ve listened to 100 times. The bass and highs seem to be decent even though I’ve been listening to them in studio mode. I’m no audiophile, but I think these are a good product for the money. When answering calls, I could hear the person on the other end clearly and the same for them hearing me. I haven’t had much experience with the noise cancellation. I plan to try it out on my next flight. I would definitely recommend these. JBL is a brand that I would recommend to someone who wants good sound and value in a moderate price range. I have a few products by JBL to prove it. Try them, maybe you’ll like them too.

[Proximity] [This review was collected as part of a promotion.] What a great listening experience! I love the fact that I can adjust the sound levels to make movie seem almost like setting in a surround sound theater, bass that sounds and make my ears feel like I'm in a car with huge speakers, and hear podcasts as if I was in the same room with the person speaking! there are way to many features to talk about in a short review, but I've had so many headphones in the past and these by far stand at the top of quality, functionality, features and sound! my wife bought another brand not to long ago, and you can see which pair she keeps grabbing lol. I can hardly get them away from her. Good thing the battery last for days and recharges so fast or I probably wouldn't get to use them at all. The range is awesome, i can leave my phone charging and walk around my house doing chores and never lose sound! Phenomenal product!

[3 Hours] [This review was collected as part of a promotion.] Overall these headphones are a bang for the price. I havent had these style of headphones where the earmuff doesn't fully cover your ear, so I was skeptical. However compared to other ones I've worn, these are actually really comfortable while maintaining great audio quality and bass. I've worn them for over 2 hours while detailing cars and they were still comfortable. I like that even for the price, they have a ton of features and paired to my S23+ almost instantly out of the box. The JBL app for these works well, though I found that some of the "audio enhancers" possibly made the quality worse. Using them on normal settings sounded better, but I'm sure this will be improved with future updates to the app and headphones themselves. Bass was pretty great and audio was clear. My favorite feature was active noise cancelation, it actually works well and I use it a ton while detailing and using a loud pressure washer. These things rock.
