## Long 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.

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.
