JBL Everest 110 Wireless Headphones Review

The JBL Everest 110 are wireless in-ears that have a non-flashy look. They're low-profile due to their small earbuds and have a slightly bland design overall. They look a bit sporty thanks to the stability fins, but that's about it. The cable is thin, and the in-line remote is a bit big compared to the rest of the headphones. These headphones come in three different colors: gunmetal, blue, and silver.

The JBL Everest 110 are quite comfortable in-ears. They don’t enter your ear canal too deeply and fit nicely in the ear. They feel stable due to the stability fins, and the rubber coating doesn’t apply too much pressure on your inner ear. They also come with different tip and fin sleeve sizes to help you find the most comfortable fit for you. On the other hand, some people may feel soreness after a while when wearing in-ear headphones like these.

These headphones have a common in-line remote that gives you access to most helpful commands like play/pause, volume control, and track skipping. However, the remote feels cheaply made, and the middle button is mushy. Multi-press commands are hard to register, and unwanted single-press commands like pausing your music can be activated instead, which is frustrating.

Like most in-ear headphones, the JBL Everest 110 don’t trap much heat inside your ears. They're suitable for sports, as you shouldn’t sweat more than usual when wearing these and you shouldn’t feel a big temperature difference.

Like most in-ears, the JBL Everest 110 are very portable. You can easily fit them inside pants pockets or in a bag. They're easy to carry around and can also rest easily around your neck. However, they don’t come with a case to protect them when you’re on the move and not using them.

These headphones don’t come with a case or a pouch to protect them.

The JBL Everest 110 are decently built headphones. The buds feel dense enough to survive a few accidental drops without suffering too much damage. However, the cable is thin, and the in-line remote feels a bit plasticky. They also don’t have any official water or dust resistance rating, unlike the similarly designed Jaybird Tarah Wireless, which are rated IPX7.

The JBL Everest 110 are stable headphones that you should be able to use when jogging or for other physical activities. They fit nicely inside the ear thanks to the stability fins and shouldn’t pop out of your ears. Their wireless design also means they get rid of a cable being in your way, which is good since a sharp tug on the cable will remove the earbuds from your ears, even with the fin sleeves put on.

The JBL Everest 110 Wireless, like most other in-ears, have excellent frequency response consistency. If the user can achieve a proper seal using the assortment of tips, they should get very consistent bass and treble delivery every time they use the headphones.

The JBL Everest 110's bass accuracy is mediocre. It's overemphasized across the range, resulting in intense thump, punch, and boom. However, some users may find this sounds very muddy.

The JBL Everest 110's mid-range is good, and the overall response is well-balanced. Low-mid is over our target curve. It's the continuation of the overemphasis in high-bass, which makes vocals thick and cluttered. However, the mid and high-mid ranges are very neutral, so vocals and lead instruments are present and clear.

The JBL Everest 110 have an excellent treble performance. The response throughout the range is fairly flat, even, and follows our curve accurately. There's a small dip in low-treble that'll have a small negative impact on the detail and brightness of vocals, lead instruments, and cymbals, but this will barely be noticeable.

These headphones have outstanding imaging. Their weighted group delay value is 0.17, which is very good. It results in a tight and fast bass and clear treble. The L/R drivers of our test unit also showed very good matching, which helps with proper placement and localization of instruments and sound effects (like footsteps) in the stereo image. However, these results are only valid for our unit, and yours may perform differently.

The soundstage performance is poor, like most other in-ears and earbuds. Activating the resonances of the pinna is a big factor in creating a large and in-front soundstage. Due to their lack of interaction with the pinna, they'll have a soundstage that is perceived, small, and located inside the head. However, unlike open earbuds like the Apple AirPods (1st generation) Truly Wireless, these earbuds have a closed design which further reduces the spaciousness and sense of openness of their soundstage.

The isolation performance is great. In the bass range, where the rumble of airplane and bus engines sit, they achieved 11dB of isolation, which is decent and quite impressive for passive in-ear isolation. In the mid-range, important for blocking out speech, they reduce outside noise by about 25dB, which is very good. In the treble range, occupied by sharp S and T sounds and A/C system noises, they isolate by more than 36dB, which is great.

The leakage performance is fantastic. These in-ears practically do not leak, so you don't need to worry about disturbing people around you unless you are blasting your music in a very quiet room. With the music at 100dB SPL, the leakage at 1 foot away averages 25dB SPL and peaks at 33dB SPL, which is significantly quieter than the noise floor of an average office.

The microphone has a mediocre recording quality. The LFE (low-frequency extension) of 269Hz means speech recorded/transmitted with it will sound noticeably thin. The HFE (high-frequency extension) of 2.6kHz is poor and results in speech that is noticeably muffled and lacking in detail. It also negatively affects the intelligibility of speech but will still be understandable in quiet environments.

The in-line microphone of the JBL Everest 110 is mediocre at noise handling. In our SpNR test, they achieved a speech-to-noise ratio of about 15dB, indicating they're best suited for quiet environments and will struggle to separate speech from ambient noise in moderate to loud situations.

We measured slightly over nine hours of battery life. It's an extra hour over the advertised eight hours, which is nice. They also take just under two hours to fully charge. However, they don’t have any power-saving feature, so you will need to remember to turn them off each time you stop using them, or the battery will drain out over time.

They don’t have a companion app to enhance your listening experience.

These headphones are Bluetooth compatible but can’t connect to more than one device at a time, which would have been helpful at the office if you were to switch between your work computer and phone often. They also don’t support NFC for an easier and quicker pairing procedure, which would have been nice since they take a long time to pair.

Like most Bluetooth headphones, the JBL Everest 110 might not be suited for watching videos. Some people may notice a delay between audio and video, which can get frustrating. However, some apps and devices seem to offer some compensation, so you might not notice it as much.

You can’t use these headphones wired.

These headphones don't have a dock.
