Live 660NC

Exceptional battery life meets a polarizing fit and inconsistent noise cancellation.

2021Updated Jul 2026

At a Glance

The JBL Live 660NC is a pragmatic choice for users who prioritize multi-day battery life and a neutral sound profile that can be customized via software. It serves well as a secondary pair for office work or commuting where longevity is the primary concern.

However, the extreme clamping force makes them a risky purchase for glasses wearers or those with larger heads. The Active Noise Cancellation is functional but lacks the refinement of premium competitors, often introducing its own audible artifacts like low-frequency rumble or whistling.

Pros
  • Class-leading battery life exceeding 40 hours
  • Highly customizable EQ via companion app
  • Stable multipoint Bluetooth connectivity
Cons
  • Excessive clamping force causing physical fatigue
  • Inconsistent ANC performance with audible artifacts
  • Low volume output specifically on Android devices

"Noise cancelling disappointed me. Firstly, when you turn it on when the music is not playing in the headphones, it appears as if the sound of rain. Secondly, noise cancelling does not really suppress noise. Thirdly, when noise reduction is turned on, it appears as if the rumble and bass begin to hammer hard. Unpleasant."

Users report that the ANC is disappointing, with one user describing it as 'shitty' and another noting it doesn't significantly suppress noise and can introduce unwanted bass.

"The highs start to smooth out a bit earlier than I would have hoped. There’s some slight detail here and there, but the timbre here ends up falling flat with an overall dull tonality."

The sound is generally bass-forward and clear in the mids, but the highs are dull and the soundstage feels overly contained, with bass sometimes becoming boomy.

"When pairing these with any Android device, like an Android phone or a Sony Bravia 4K TV, the volume is excessively low, like the ones I bought require me to have the volume up all the way to 100 and even there they're just adequate, not loud"

A major connectivity issue is reported with extremely low volume when paired with Android devices, and some users struggle to connect to the app or find touch controls annoying.

The Battery King with a Vise Grip

The JBL Live 660NC occupies a strange middle ground in the mid-range ANC market. While it boasts battery specs that embarrass flagship models from Sony and Apple, the physical user experience is a point of intense friction. Reviewers are split between praising the durable construction and lamenting a design that feels physically aggressive on the skull.

Initial Impressions vs. Long-Term Reality

Professional tech blogs initially lauded the 660NC for its premium material blend of aluminum and leather, noting its high-function feature set. However, long-term feedback from Reddit and YouTube reveals a different story. While reviewers might tolerate the fit for a two-hour testing window, daily users report significant discomfort. One tech reviewer noted that

"the clamp force is incredibly tight and feels like your head is caught in a vise, applying unwanted pressure on the skull."

Long-term owners also highlight a technical quirk often missed in short-term reviews: a software-level volume disparity. Android users frequently complain that the headphones lack headroom, requiring 100% volume just to reach moderate listening levels. As one YouTube commenter noted:

When pairing these with any Android device, like an Android phone or a Sony Bravia 4K TV, the volume is excessively low, like the ones I bought require me to have the volume up all the way to 100 and even there they're just adequate, not loud

Audio Performance and ANC Friction

The sound signature is surprisingly neutral for a JBL product, which has become a point of contention. Purists appreciate the clarity, but those expecting the brand's signature 'Pure Bass' out of the box will be disappointed. The companion app's EQ is not just a feature; it is a requirement for a satisfying experience.

Noise cancellation remains the most divisive metric. While blogs call it 'effective for the price,' Reddit users report that the ANC system often introduces more problems than it solves. Users have documented a strange 'rain-like' hiss and low-end rumble when the circuit is engaged. One Reddit user summarized the frustration:

Noise cancelling disappointed me. Firstly, when you turn it on when the music is not playing in the headphones, it appears as if the sound of rain.

This lack of refinement in the ANC algorithm suggests that while the hardware is capable, the processing lags behind the industry standard, creating a 'whistling' effect in transparent modes that many find distracting during calls or outdoor use.
