[This review was collected as part of a promotion.] If you're a big dude like me you'll find comfort in knowing that these headphones will fit your head perfect I've never found a pair of headphones that fit my head so comfortably not only are they comfortable they look good while you're wearing them the sound is amazing you can customize it anyway you like with the JBL app ....the noise-cancelling is perfect the JBL Everest Elite 750 NC is the real deal!!! You owe to yourself to to own a pair!

I've tried / purchased the top of line Bose and Sony NC headphones... Bose and Sony both had excellent acoustics but we're hollow on the low end. Construction was excellent or good /respectively. The JBL Everest Elite 750 NC are every bit the same. NC performance is as good but slightly different. Not worse or superior. Build ... Sony were slightly off but near 97% comparable. The JBLs fit well with perfect perimeter pressure and weight/bulk. Critically, JBL boasts tighter more powerful bass. I seem to FEEL more low end pressure well in excess of Bose or a distant Sony performance. In my profile of demand JBL wins easily with an edgy SQ, matching performance in build and acoustics combined with lower actual cost! Five stars easily! I might add I like the amplified mode ... However... We bought two sets and my daughter complianed one set has a faint humming in the background when sync'd on BT. I only heard it in silent transitions and judged it insignificant. So she uses the perfect set and I'm fine with the near impossible to hear humm with age 50+ ears. Final word... I've got a pair of iconic JBL 100 studio monitor (not true 4311 monitors) refurbished with factory original foam surrounds. So yeah... I'm partial to the JBL mix of acoustic character. Actually the Bose and Sony had unacceptable bass performance... JBLs were like the 3 bears with Goldilocks where the porridge was "just right"... Yeah... JBLs were perfect for acoustics!

[This review was collected as part of a promotion.] This headphones came in great packaging. They come with all the accessories you will need including an adapter to use on an airplane. My first thoughts when opening the box was how well everything is packaged. The headphones come in a very durable zip up case that is used to store them. Once you open the case the headphones are neatly folded next to the small accessory pouch. I removed the headphones and removed the included usb charging cable from the pouch. They took about an hour to get to full charged. I like how there is a charging light that stays lit while it charges. Once charged I turned on the headphones which went into pair mode. I was pairing them to an iPhone 7. Synced up without an issue. I downloaded the JBL headphone app. The headphones work great with the app and helps setup the headphones. Similar to a home theater receiver, the headphones let out a delayed tone. The headphones were now ready to be used. My first impression of the sound was that it was clear and undistorted. I could here a full range of frequencies without having to turn up the volume. I wouldn't call these bass heavy headphones. They capture and produce a full frequency range. I listened to the headphones for 8 hours straight. They are extremely comfortable. They encapsulate my entire ear and don't feel heavy. The controls on the right ear are a bit cumbersome. Its hard to figure what is what without knowing the order of the buttons. I like having a smart button to program for features such as the NCS. The NCS system built into these headphone is awesome. I have four loud kids!!! These headphones drowned them out and allowed my to enjoy my music for hours. One feature I am a fan of is the fact you can adjust the amount of ambient noise you can hear. At certain times of the day I need to hear what is going on but still want to hear my music. With the app or the programming of the smart button, I can adjust it to my liking. I can hear my surroundings and my music while being encased in these headphones. The cons to these headphones are that if you don't have them sitting around your ears perfectly they tend to make a funny sound. The sound is as if the headphones are distorting. This occurs when the NCS function is active. If you seal the headphone to your head with slight pressure then you won't experience this. I also wish these were a little louder. With the initial "JBL" the should JUST BE LOUD. Overall I am enjoying these headphones. They are made for listening while relaxing. They offer great sound insulation and are great quality. The battery life was about 10.5 hours with the NCS feature on. Once the battery had depleted I had plugged them into my phone and I was able to continue to enjoy my music. It was great to all be able to fine adjust the frequencies of the headphones via the app. I was able to save and name my settings. This is an important feature for me when listening to music. I have a series of headphones that I own and I will say these are one of my favorites due to the noise cancelling properties, they are very comfortable and they have great sound while being transmitted via bluetooth. I also like how I walked around my entire house while leaving my phone in my bedroom and these headphones never lost connection. I even went into my basement to do my laundry and they never lost connection. I have a good size 3 bedroom house with a full basement. I found this range very impressive.
