Product information

Description

The Intenso O400HA over-ear headphones provide flexible listening options and clear sound for everyday use. They offer multiple modes — music mode for balanced reproduction, Hybrid Active Noise Cancelling (ANC) that reduces ambient noise by up to 35 dB, transparency mode to let important external sounds through, and passive wired mode via the 3.5 mm jack for use without battery. The headphones feature 40 mm drivers, Bluetooth 5.3 wireless connectivity with up to 15 m range, and a foldable ergonomic design for comfortable, space-saving transport. The 600 mAh battery supports up to 75 hours of playback and fast charging gives about 6 hours of use after a 15-minute charge. In the box: headphones, USB-C to USB-C cable, and a 1.5 m 3.5 mm audio cable. Available in black, white, pink, and blue.

Advantages

Multiple listening modes (music, Hybrid ANC, transparency, passive wired) adapt the Intenso O400HA to different environments and preferences. Long battery life up to 75 hours combined with fast-charge capability ensures extended use and quick top-ups when needed. Bluetooth 5.3 provides a stable wireless connection up to 15 meters, while the 3.5 mm cable and foldable construction add wired compatibility and portability. Lightweight circumaural design with 40 mm drivers delivers clear and powerful sound across music styles.

Suitable for

  • Daily music listening at home or on the go
  • Commuting and travel where ANC helps reduce ambient noise
  • Remote work or study requiring focus with reduced distractions
  • Wired listening when battery is depleted or for low-latency use

How to use

Charge the headphones via the USB-C port until fully charged (about 2 hours). Select the desired listening mode using the device controls: music mode for standard playback, ANC to reduce background noise by up to 35 dB, transparency mode to hear surroundings, or connect the 3.5 mm cable for passive wired listening without battery. Pair the headphones with a Bluetooth 5.3 source within 15 meters for wireless use, or connect via the included audio cable when preferred.

Usage recommendations

For optimal ANC performance, ensure ear cups form a good seal around the ears and update device firmware if updates are available. Use transparency mode when you need situational awareness, and switch to wired mode for critical low-latency applications.
