JBL Live 670NC specifications and in-depth review

JBL Live 670NC

Manufacturer: JBL

The JBL Live 670NC is an on-ear headphone that combines wireless convenience with active noise cancellation, making it a well-rounded option for everyday listening. Weighing 219 g and designed to fold flat, it travels reasonably well despite the absence of a dedicated carrying case. Both a detachable cable and a tangle-free cable are included, giving users the flexibility to switch between wired and wireless use as needed. Bluetooth 5.3 keeps the wireless connection current, and the headphone also supports LE Audio for forward compatibility.

On the technical side, the JBL Live 670NC uses a 40 mm driver unit with a frequency range of 20 Hz to 20,000 Hz, an impedance of 32 Ohms, and a sound pressure level of 98 dB/mW. Spatial audio support and passive noise reduction complement the active noise cancellation system. The 850 mAh rechargeable battery delivers up to 65 hours of playback, or 50 hours with ANC active, and fully recharges in around 3 hours via USB Type-C. Two microphones handle calls and voice input through a noise-canceling mic setup, and the headphone supports two simultaneous Bluetooth connections via multipoint pairing. An ambient sound mode and on-device controls round out the feature set.

Pros
  • Battery life reaches 65 hours on a single charge, dropping to a still-generous 50 hours with ANC active
  • Supports two simultaneous Bluetooth connections via multipoint pairing, useful for switching between devices
  • Both active noise cancellation and passive noise reduction are present, offering layered ambient noise management
  • Folds flat and includes a detachable cable, making it more manageable for transport
  • USB Type-C charging with a battery level indicator adds day-to-day convenience
  • Ambient sound mode allows awareness of surroundings without removing the headphones
Cons
  • No travel bag is included despite the headphone being foldable
  • Bluetooth range is limited to 10 m, which is relatively short for a wireless headphone
  • Does not support any high-quality audio codecs such as aptX, LDAC, AAC, or LDHC
  • No in/on-ear detection means playback does not pause automatically when the headphones are removed
  • Wireless charging is not supported, requiring a wired connection for every charge
  • No fast pairing or NFC pairing, so connecting to a new device follows a manual process
Who is this for?

The JBL Live 670NC suits users who spend long hours listening throughout the day, thanks to its 65-hour battery life that minimizes the need for frequent recharging. The combination of active and passive noise reduction makes it a practical choice for those working or commuting in moderately noisy environments where blocking out distractions matters. Its multipoint pairing for two devices and headset capability also make it a reasonable fit for people who regularly switch between a work computer and a phone, or take calls alongside regular listening sessions. The foldable build and detachable cable add a degree of everyday practicality for users who move between different settings.

Who is this NOT for?

Users who prioritize high-resolution audio streaming will find this headphone limited, as it lacks support for advanced codecs such as LDAC, aptX, or AAC, meaning audio is transmitted without the benefit of higher-quality wireless formats. The 10 m Bluetooth range is also a drawback for anyone who needs reliable wireless coverage across a larger space, such as moving between rooms. Additionally, those who want seamless device interaction — such as automatic playback pause when the headphones are taken off — will be disappointed by the absence of in/on-ear detection. The lack of a travel bag and water resistance also makes this a poor match for outdoor or physically active use cases.

The JBL Live 670NC supports both wireless and wired connectivity, with the wireless side running on Bluetooth 5.3 and covering a maximum range of 10 m. It includes Bluetooth LE Audio, though it does not support aptX, aptX Adaptive, aptX HD, aptX Low Latency, aptX Lossless, LDAC, LDHC, or AAC codecs. Fast pairing and NFC-based pairing are also absent, so initial setup follows a standard Bluetooth pairing process.

The JBL Live 670NC can be used as a headset, equipped with two microphones that include noise-canceling capability for cleaner call audio. It supports multipoint connectivity for up to two devices simultaneously, and controls are handled through an on-device panel rather than an in-line remote on the cable. An ambient sound mode is available for situational awareness without removing the headphones, though there is no in/on-ear detection to pause playback automatically, and no dedicated mute function is present.

Final Verdict

The JBL Live 670NC is a well-equipped on-ear headphone that makes a strong case for extended daily use, with its 65-hour battery life and layered noise management standing out as its most practical assets. Bluetooth 5.3 with LE Audio support, multipoint pairing, and a functional headset setup give it a solid foundation for users who move between devices and environments throughout the day. That said, the absence of high-resolution audio codec support and the modest 10 m wireless range signal that this is a headphone built around endurance and convenience rather than audiophile-grade performance. For listeners who prioritize long-lasting, versatile everyday use over premium wireless audio fidelity, the JBL Live 670NC delivers a coherent and capable package.
