Product information

Description

The Intenso O400HA over-ear headphones provide flexible listening modes and clear sound for everyday use. Music mode delivers balanced audio reproduction, while Hybrid Active Noise Cancelling (ANC) reduces ambient noise by up to 35 dB for focused listening. Transparency mode lets important external sounds through so you remain aware of your surroundings, and passive wired mode via the 3.5 mm jack enables listening without battery power. The headphones feature 40 mm drivers, Bluetooth 5.3 wireless connectivity with up to 15 m range, and a lightweight circumaural design for extended comfort. The package includes a USB-C to USB-C charging cable and a 1.5 m 3.5 mm audio cable, and the model is available in black, white, pink, and blue.

Advantages

The O400HA combines long battery life—up to 75 hours—with fast charging that provides about 6 hours of playback after 15 minutes of charge. Hybrid ANC offers significant noise reduction (up to 35 dB) while transparency and passive wired modes provide situational flexibility. The foldable, adjustable design and light weight (≈248 g) support comfortable extended wear, and Bluetooth 5.3 ensures a stable connection up to 15 m. Included cables enable both wireless and wired use.

Daily music listening at home or on the commute

Long travel or extended listening sessions
Wired use when battery is unavailable or for devices without Bluetooth

How to use

Charge the headphones via the USB-C port before first use. For wireless use, enable Bluetooth on your source device and pair with the Intenso O400HA; maintain a distance within 15 m for reliable connection. Switch between music, ANC, transparency, and passive wired modes using the on-device controls; connect the 3.5 mm cable for wired listening or when battery is depleted. Use the adjustable headband and ear cushions to obtain a comfortable fit, and fold the headphones for compact transport.

Usage recommendations

For best ANC performance, ensure ear cups form a good seal around your ears and keep firmware or device software updated if applicable. Use fast-charge when short on time; for maximum battery longevity, avoid keeping the battery at full charge for prolonged periods and store the headphones in a cool, dry place.
