JBL Everest Elite 750NC Review
The JBL Everest Elite 750NC is JBL’s flagship Bluetooth headset. The successor of the Everest Elite 700 and the big brother of the Everest 710, it is adorned with all the features expected from such a headset, including active noise reduction.
- Good wearing comfort
- TruNote calibration
- Good noise canceling
- Somewhat short battery life
The JBL Everest Elite 750NC is made in the same mold as the Everest 710 that we have already tested. Therefore, the design, materials, comfort, and use are extremely similar. Therefore, we invite you to read the test of the latter to know all the details and approach this test.
The design of the JBL Everest Elite 750NC is not subtle since it is adorned with imposing over-ear headphones. The design could have been a little more reassuring to the touch – the plastic shells do sound a bit like those when tapped – that said, the set feels sturdy, and the finishes neat. Lightness is the order of the day. Failing to create a headset with an ultra-discreet look, JBL had a good idea to make it foldable so that it takes up less space when not in use and easily slip it into its hard carrying case.
This model provides great feelings of comfort. The consequent deployment of the arch allows all heads to put on the helmet easily. It naturally finds its place, the weight and pressure points are well distributed, the ear cups largely encompass the horns, and the contact with the imitation leather pads is pleasant. It only lacks a hair of depth at the level of the ear cups and thickness at the level of the pad of the hoop to raise it to the level of the very best.
The Everest Elite 750NC hosts all the commands expected on a nomadic headset: a monostable switch to turn the headset on / off, two buttons for managing the volume/navigation between the tracks (while keeping pressed), another to manage music playback/calls and invoke the smartphone’s voice assistant, a fourth to start Bluetooth pairing and a final one to activate/deactivate active noise reduction or activate the Ambient Aware function.
By keeping the latter pressed, the TrueNote calibration function is activated on the fly, which unfortunately does not change the sound rendering or the active noise reduction performance. Numerous voice indications, only in English, are integrated for ease of use. We don’t miss anything, and the buttons are responsive. However, their positioning and contact are not optimal. It takes a few sessions of use to find them instinctively, even if some keys have keys.
There are some differences in connection possibilities, especially this model’s limits compared to some direct competitors. Bluetooth 4.0 (no information on compatible codecs, but only SBC would probably be supported) is present for the wireless connection. Therefore, no way to directly know the battery level on the interface of his smartphone, for example. The ShareMe 2.0 function (integrated on the Everest 710) is not in the game. Multipoint pairing must also be crossed out; only one Bluetooth connection is possible simultaneously.
The latency of wireless communication is not the most contained. Even if we manage to follow our video correctly, we still perceive a very slight delay through mobile applications (Facebook, YouTube, Netflix…), which natively compensate for the latency in Bluetooth. Apart from this use (other application or connection on PC), the delay is noticeable. It is still possible to use the Everest Elite 750NC wired, thanks to the 3.5 mm mini-jack input, but this deprives us of certain controls (volume, activation of certain features). Charging takes place via the micro-USB port. Both cables are provided.
The JBL Headphones app (Android / iOS) provides additional features, including a graphical EQ or display of the remaining battery level and access to advanced settings. The navigation is fluid and relatively intuitive, although we would have appreciated changing the display language.
The autonomy promised by JBL for this model is 15 hours with active noise reduction (RBA) engaged and 20 hours without, which is low compared to the competition. In reality, alas, we have never managed to achieve these two promises. With the RBA on, we timidly approached 14 hours of use at a comfortable listening volume. Without it, the usage time is around 21 hours, in the best case—a value both far from the promise of JBL and the competition.
The built-in microphone in the JBL Everest Elite 750NC does not shine its efficiency. It is not very directive and does not separate the surrounding noises from the voice. It is, therefore, difficult to hold a conversation in a noisy street since our voice is very often masked by what is happening around us. On the other hand, it’s a little easier in quiet environments. In this case, the capture is correct, but the voice still lacks clarity, the rendering is still muffled. This goes much better with the microphone located in the cable (better clarity and better intelligibility), even if the surrounding sounds are audible again.
As is often the case with Bluetooth headsets with active noise reduction, the JBL Everest Elite 750NC offers a different sound experience depending on whether this feature is activated.
This model provides balanced sound reproduction when noise reduction is turned off, whether in wired or wireless use. The bass is right where it belongs while still being deep and well-defined. Although they would have deserved a little more liveliness and percussion, there is no masking effect. The timbres are respected, the voices are perfectly intelligible and clear, no frequency band takes precedence over another. Extension in the highest frequencies is ensured. This gives a good feeling of air and space.
On the other hand, the stereophonic width is not incredible, even if one can correctly identify and replace all the sources on the horizontal plane. That said, a balanced frequency response isn’t everything. Indeed, the behavior of the membranes is far from exemplary from midrange to treble. The reproduction of these areas lacks precision and detail. The result is noticeable when you listen. This brings a bit of a sharp edge in the mid / high-midrange and is slightly metallic in the treble (well audible on the sibilants of the voice and the cymbals, particularly the hi-hat).
Activating active noise reduction also engages the DSPs, and a native equalization is described as wild as it exaggerates the low frequencies excessively. These are fully propelled at the front (we are still talking about a boost of +15 dB on average on the 20/120 Hz band, with a gentle decay down to 600 Hz. The result is a very strong masking effect on the higher frequencies and a sensation of impact and pressure far too important. In addition, it causes very rapid hearing fatigue. The EQ offered in the application, which remains active once applied, is a great help here since it will drastically reduce this awful overweight. You can go liberally in the tuning by creating a low cut below 1kHz; it is impossible to go below -9 dB of compensation. For a little more smoothness and balance, you can also create a slight dip around 6 kHz.
The Everest Elite 750NC offers proper passive isolation capable of cutting out a minimum of surrounding noise. However, you will still be able to perceive the conversations around you and various noises, especially those coming from low frequencies (motors, wind tunnels …). The active noise reduction is well made here but far from the tenors of the genre that are the QC35 II, WH-1000XM3, and PX. However, it is less effective on variable noise (conversations). Let us clarify two things: activating active noise reduction causes very subtle background noise (like white noise) noticeable only when using the headphones in silence, as well as a small pressure effect that can inconvenience very sensitive people on this point.
The Ambient Aware function is effective in practice, although listening is not at all-natural. The microphones indeed focus a lot on the mediums (between 200 and 2 kHz), which gives the rendering a “telephone” aspect (narrow and somewhat nasal voices). However, at least the voices (conversations and external voice alerts) are put forward.
The JBL Everest Elite 750NC narrowly gets the fourth star, provided you take the time to correct its behavior when using Active Noise Reduction. The competition is still particularly tough, and this headset’s price/quality ratio is not the most interesting on the market. Some less expensive models (like the HD 4.50 BTNC, the Backbeat Go 810, or the Backbeat Pro 2) are worth a look if you are looking for a good Bluetooth headset with RBA. For a slightly higher price, there are even other essential references such as the WH-1000XM2 / XM3 and the QC35 II.
