2. Design and Build – Lightweight, Foldable, and Comfortable

The JBL Tune 780NC features an over‑ear design with generously padded leatherette ear cushions and a padded headband. Weighing approximately 225‑235g, it is lightweight enough for extended wear without neck fatigue. The clamping force is moderate – secure without excessive pressure, though users with larger heads may find it a bit tight initially (the headband loosens slightly over time). The ear cushions are soft and breathable, and the headband is adjustable.

The foldable design is a highlight: the ear cups swivel flat and fold inward, reducing the size for easy storage in a backpack or laptop bag. A soft pouch is not included, but the compact form makes packing simple. The build is made of matte plastic that resists fingerprints, available in several colours.

Physical buttons on the right ear cup control power, volume, playback, ANC/ambient modes, and voice assistant. The USB‑C port for charging is located on the bottom edge. A 3.5mm jack is not present; these headphones are strictly wireless, so you cannot use them passively when the battery is dead.

3. Battery Life – 76 Hours with ANC Off, 50 Hours with ANC On

The JBL Tune 780NC offers exceptional battery endurance. With ANC off, you get up to 76 hours of continuous playback – one of the longest in its class. With ANC on, you still get an impressive 50 hours. For moderate users, this could mean weeks of use without recharging. Even heavy users will get several days of listening.

Fast charging delivers 5 hours of playback from just a 5‑minute charge – perfect for when you forget to charge overnight. A full charge takes approximately 2 hours via USB‑C. Battery status can be monitored via the JBL Headphones app or LED indicator on the headphones.

4. Audio Performance – 40mm Drivers with Pure Bass and Spatial Sound

The JBL Tune 780NC are equipped with 40mm dynamic drivers tuned to JBL’s signature Pure Bass Sound. The sound signature is characterised by elevated low frequencies – kick drums, bass guitars, and synth lines have satisfying punch and warmth. This makes them particularly enjoyable for genres like hip‑hop, EDM, pop, and rock.

A standout feature is Spatial Sound, which creates a more immersive, 3D‑like listening experience. This is especially noticeable with movies, games, and live recordings, adding width and depth to the soundstage. You can toggle Spatial Sound on/off via the JBL Headphones app. The headphones support AAC codec for high‑quality streaming on both iOS and Android.

Through the app, you can further customise the sound using a 5‑band EQ – reduce the bass for a more neutral signature or boost treble for more sparkle. The Personi‑Fi 3.0 feature creates a personalised hearing profile based on a simple hearing test, tailoring the audio to your unique ears. Volume levels are more than adequate, and distortion is minimal even at high levels.

5. Adaptive Noise Cancellation and Ambient Modes

The JBL Tune 780NC features adaptive Active Noise Cancellation (ANC) that automatically adjusts the strength of noise cancellation based on your environment. For example, on an airplane, it blocks more low‑frequency engine rumble; in a quiet room, it reduces ANC to save battery. While not as powerful as Sony or Bose flagships, it is very effective for the price, significantly reducing ambient chatter, traffic, and HVAC noise.

Smart Ambient technology includes two modes:

• Ambient Aware – Lets in external sounds (announcements, traffic) without removing the headphones

• TalkThru – Lowers music volume and amplifies voices for quick conversations

You can toggle between ANC on, Ambient Aware, and TalkThru using a dedicated button on the ear cup.

6. Dual Beamforming Microphones for Clear Calls

The JBL Tune 780NC features dual beamforming microphones with noise reduction. This advanced system precisely captures your voice while actively filtering out background noise – such as traffic, wind, office chatter, or construction sounds.

In practice, this makes voice calls significantly clearer than previous JBL Tune models, even in moderately noisy environments. For remote workers, frequent callers, or anyone using the headphones for Zoom meetings, this is a major upgrade. The built‑in VoiceAware technology lets you control how much of your own voice you hear during calls (via the app or button combination), preventing you from speaking too loudly.

7. Bluetooth 6.0 and Multipoint Connection

The JBL Tune 780NC features Bluetooth 6.0, the latest version of the wireless standard. Benefits include:

• Faster pairing – Connect quickly to devices

• Lower latency – Improved audio‑video sync for gaming and video

• Improved power efficiency – Contributes to the long battery life

• Extended range – Maintain connection up to 10 metres

• Better coexistence – Fewer dropouts in crowded wireless environments

Multi‑point connection allows you to connect to two devices simultaneously – e.g., your laptop for Zoom calls and your phone for music – seamlessly switching between them. This is a huge productivity boost for remote workers. The headphones also support Google Fast Pair on Android for effortless initial setup.

8. JBL Headphones App – Custom EQ and Personi‑Fi 3.0

The JBL Headphones app (available for Android and iOS) unlocks several features:

• EQ presets – Choose from Default, Bass, Vocal, or create a custom 5‑band EQ

• Spatial Sound – Toggle the 3D audio effect on/off

• ANC/Ambient mode settings – Adjust the level of noise cancellation

• Personi‑Fi 3.0 – Take a hearing test to create a personalised sound profile tailored to your ears

• Voice prompt settings – Customise or disable voice announcements

• Firmware updates – Keep the headphones up to date

• Battery status – View precise remaining charge

The app is user‑friendly and enhances the overall experience. For Android users, the app integrates seamlessly with the Android ecosystem.
