I’ve owned and enjoyed JBL products for decades. It’s one of the first brands I think of when I want high quality audio. The Everest Elite 750NC enhances my positive perception that JBL usually offers excellent sound reproduction. The earphones’ design is not unique when compared to others—the basic design has after all been around since WWII—but it is very comfortable and could easily be warn for long flights. The noise canceling function is very good in most settings. (Note, however, these do not appear to be ANSI-rated for ear protection when working with machinery or in other industrial environments, although I could not find any such warning or information in the voluminous, unreadable multi-lingual documentation. In sum, here are the positives: Comfort; Very good music reproduction; Easy Bluetooth pairing; Rechargeable battery; Includes compact case, necessary cords, and airplane adapter; Good noise-canceling function. What more could one ask? A lot in this case. JBL seems to have fallen into the contemporary trap of equating complexity with quality. I’ve owned high-quality noise canceling (non-Bluetooth) headphones for more than a decade, and it has ONE function button. The JBLs have SEVEN extremely small controls, all clustered on the right earphone. One would think that mastering these would be helped by informative instructions. Not so! Obviously, JBL intends to sell these world-wide, and thus includes a “Quick Start Guide” that has 28 foldout panels with 4- or 5-point type face, virtually unreadable and useless. The only way I could get instructions was to (1) download the guide from JBL;’s website, (2) enlarge the pdf document by 400%, and (3) print relevant (English) pages. Even the few graphics (see photo) are nearly indecipherable. The unit is warranted for one year (typical) but contains the notice that the earphones “may deteriorate from use or storage.” In sum, these are good earphone that are overburdened by—and overwhelm the owner with—too many functions (e.g., “Ambient Awareness,” “TruNote Calibration”) and excessive complexity.

The "NC" in the model # of Everest Elite 750NC should stand for "NO COMPARISON"! They are truly in a class by themselves. LIKES: 1- Stunning Audio: tight bass, sweet highs, clear vocals: 10 - 22,000 Hz frequency response 2- Longest Bluetooth range of any device I have ever tested, while delivering sweet music & telephone calls for up to 20 hours via the internal Li-ion rechargeable battery 3- Lightweight & extremely comfortable for extended use / across the country flights 4- Buttons are organized in a logical arrangement on the headphones & allow Power: On / Off; Bluetooth: On / Off; Telephone Call: Pick-Up / Hang-Up; Volume: Up / Down; Music Control: Play / Pause; Forward / Backward; NC: On / Off; Ambient Aware: Low / High / Off 5- Foldable for quick, no fuss storage with carry case included - see photo showing headphones folded in carry case 6- Noise cancellation is extremely effective across the entire frequency spectrum 7- Ambient Aware allows you to adjust the amount of isolation from your environment. This is individually & completely adjustable by the wearer, even tunable for each ear separately. See photo of the headphones in the acoustic test room (our theatre) 8- TruNote Auto Sound Calibration calibrates the sound of the headphone to the individual wearer. A personalized sound equalization is created for each user independently 9- Completely customizable audio equalization is effortless via the app. The app also provides the gateway for future headphone software upgrades. The JBL App even allows adjustments to be made from the app, rather than just from the buttons on the headphones 10- Wired or Bluetooth connect, with adaptors included in a special pouch within the carry case, shown in photo DISLIKES: NONE! SUMMARY: JBL Everest Elite 750NC (NC = "No Comparison") Over-Ear Noise Cancelling Wireless Headphones are truly in a class by themselves. I was totally blown away by the audio quality & customizable design of these personal listening devices & unequivocally recommend them!!

First off, let's start off by saying these headphones do sound good, clear and well balanced. But at this price point, that is really the minimum expectation here. For the issues: 1. Noise cancelling could be better. I tested while mowing my lawn on my riding mower, and these did not cancel as much noise as another cheaper pair of noise cancelling headphones that I have. Also, I am not sure how useful being able to control the amount of noise cancelling really is for me. When I use noise cancelling, I use it so I can block out everything, not so I can block out "almost" everything. 2. Controls on the headset are really lacking and are hard to find without taking it off. All the buttons feel the same, so it is difficult to know what you are doing without taking the headset off and you only seem to have the ability to pause and change volume from the headset itself. Other good points are: These are very comfortable, you could easily where these for a long time if you had to. The included hard case is nice for travel. If these headphones cost about $100 less, I'd give them a better rating, but for price, it is really hard to excuse it's drawbacks.

I believe the folding option of these has caused them to fail early. They started coming apart awhile back and finally broke.

I just got these headphones in the mail yesterday. One thing that got my attention was how stylish the whole set up is, everything from the box, to the carrying case. It's just the carrying case and inside includes the aux cables, audio inputs, and the headphones themselves. The buttons to control volume, power, and Bluetooth are small, they are located on the right side of the headphones. You'll have some trouble at first but you'll get used to them. The cushion from the headphone feels okay, after an hour of use, they still felt comfortable. Although i must say, the cushion looks like it will get worn out fast (just from past experiences). The headphones themselves do not feel sturdy for me. The headphones are made of plastic with a metal attachment. I don't like the plastic feel and the sound the headphones make when i put them away in my carrying case. It sounds cheap, the plastic squeaks, if the makes sense. I don't know, for the price you'll think they would feel sturdier. That's the one big thing about these, thus minus the one star. Now to the sound quality. It is what you expect of JBL. The lows are great and the highs are great as well. I played anything from beethoven to Metallica and they sounded great. Very good sound just what you expect from JBL. I will say that the noise cancellation wasn't too great. I could still hear outside noise which is a big disappointment because i would like to use this option while studying at home or school. You can't hear outside noise if you turn up the volume high, but still Noise cancellation should try to eliminate outside noise and these don't do a good job. I think the sound is great but it's the lack of sturdiness and noise cancellation that make not want to recommend these headphones to a friend.
