Product information

Description

The Intenso O400HA over-ear headphones provide flexible listening options and clear sound for everyday use. They offer multiple operating modes including 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 audio jack for battery-free listening. Lightweight and foldable, the headphones support Bluetooth 5.3 with a wireless range up to 15 meters and house 40 mm drivers for detailed audio across music styles. The package includes a USB-C to USB-C charging cable and a 1.5 m 3.5 mm audio cable; available colours include black, white, pink (rose) and blue.

Advantages

The headphones combine Hybrid ANC, transparency mode and passive wired operation to suit different environments and preferences. Long battery life of up to 75 hours and fast-charge capability (6 hours playback after 15 minutes charging) provide extended use with quick top-ups. Bluetooth 5.3 ensures a stable wireless connection while the foldable ergonomic design and lightweight construction (about 248 g) improve comfort and portability.

Suitable for

Listening to music at home, work or on the go
Commuting and travel where noise reduction is needed
Online meetings or calls using a wireless connection
Use with devices via wired 3.5 mm jack when battery is unavailable
