Everest Elite 750NC

"The sound is good in my opinion. The sub-bass is a boosted by a bit... The soundstage is kind of like you're in a music hall, but it wasn't built correctly or it was too small."

Sound is considered good by some, with a liked boosted sub-bass, but others find it unbalanced and the soundstage lacking.

"The pads for the headphones are nice but could be a bit better. My ears fit inside of the pads, but the backside of the pad gets exposed so it's not very snug."

While the ear pads are comfortable, the fit is not always snug, and the headband is noted as less comfortable for extended wear.

"My pair of everest elite 750ncs have a crackling/static sound in the left ear that changes if you move the headphones..."

Multiple users report significant build quality issues, including cracking plastic and degrading cables, leading to product failure.

"I have the Everest Elite 750NC headphones and the noise cancelling function as well as the microphone are not working properly."

The microphone functionality is questioned, with users experiencing issues with noise cancelling and mic performance, and uncertainty about mic location.

"When comparing wired vs. wireless, there's a minor decrease in quality for wireless, but losing the Bluetooth controls for the minor difference is worth it."

Bluetooth connectivity is functional with low latency, but users note a slight quality decrease compared to wired, and some struggle with PC connectivity.

"The sound quality is very good. The low tones are also definitely present."

Users consistently praise the sound quality, noting full bass and clarity, with the ability to further customize via the app making it a strong point.

"The click-adjustable metal band gave me a very comfortable fit with most of the pressure on the top of my head..."

The headphones are generally described as light and comfortable with pressure distributed well, though one source notes carrying comfort as 'mediocre'.

"The battery of the headphones lasts up to 15 hours when both noise canceling and Bluetooth functions are enabled."

The battery life is rated at up to 15 hours with ANC and Bluetooth active, and up to 20 hours with ANC off, with a relatively quick 3-hour recharge time, meeting user expectations.

"Unfortunately, these headphones break after a few months. There is a strange crackling sound when switching on the noise canceling."

Despite a good initial impression and included case, multiple reports of ANC failing or crackling after only a few months suggest significant durability issues.

"JBL’s headphone app allows you to fine-tune the headphones’ settings to your preference."

The adaptive ANC, companion app for customization, and TruNote auto-calibration are highlighted as strong features, though the lack of aptX codecs is a drawback for some.

"But they have great vocal separation, the bass is decent, and the highs are clear to a certain extent. if you're listening to something with a lot of bass or really high highs then thats where these head phones start to suffer."

Sound quality is described as decent at moderate levels, but struggles with muddied bass and blown-out highs at higher volumes or with complex tracks.

"I just want to point out that comfort wise these get an eleven out of ten. the clamping force on the head phone is just perfect so it doesn't feel like its squeezing your head."

Users consistently praise the comfort of the headphones, noting their lightweight design, good padding, and comfortable clamping force for long listening sessions.

"But in my own test with noise canceling on and the head phones set at 75 percent volume i got a better life of 12 hours. so its not the greatest compared to others on the market"

The battery life falls short of advertised claims and competitor offerings, with real-world usage yielding significantly less than the expected 15-20 hours.

"These are hooooorrible in quality.Three units warranty replaced so far.Under a year.Don’t buy.That plastic will crack."

Multiple reviews express concern over the predominantly plastic construction, with some users reporting cracking and durability issues, leading to warranty replacements.

"People didn't even know i was talking to them through my headphones and the call quality was crystal clear for them."

The echo-canceling microphone is highlighted as a significant positive, providing crystal clear call quality for the person on the other end.

"Im just surprised JBL decided to use Bluetooth 4.0 instead of Bluetooth 4.2. When it comes to sound quality these ear phones sound OK."

While the app offers useful features like EQ and ANC control, the use of Bluetooth 4.0 is a major drawback, limiting multi-device connectivity and feeling outdated for the price.
