| Drivers / Audio |
40 mm drivers. Leak-tolerant design (so good isolation even when sound leaks matter) with high fidelity sound especially for music. Music frequency range ~20 Hz–20,000 Hz. |
| Microphones |
Total of 10 mics (combination of analog + digital MEMS) for very strong voice pickup and noise suppression, especially in noisy or open office environments. Hidden boom arm for mic that can stow away when not needed. |
| Noise Cancellation / Isolation |
Digital hybrid ANC (active), plus extensive passive noise isolation (over-ear cups, sealing), plus “hear-through” / ambient modes. It’s meant to block out a lot of background noise. |
| Battery Life |
Up to ~ 37 hours (with ANC off) for music mode. With ANC on, battery drops (in many reviews / datasheet ~ 32 hours). For talk time or with “Busylight” on, less. |
| Connectivity |
Bluetooth 5.0; includes a USB adapter (Bluetooth dongle – Jabra Link 380 or 390 depending on variant) for PC/softphone use. Also supports a wired connection via 3.5 mm jack. Pairing with phones/devices + PC. Able to maintain connection ~30 meters under favourable conditions. |
| Controls / Additional Features |
– Busylight (visible from all directions) to signal when you’re in call / busy. – Foldable/hidden mic boom arm so you can hide it when you’re listening or not in call. – Soft memory foam ear cushions + premium headband for comfort. – Supports app customization (Jabra Sound+, Jabra Direct) for firmware updates, EQ etc. |
| Weight / Physical Dimensions |
~ 286 g. Over-ear style, closed cups. Big (but that’s expected for this class). |
