## Long description

The Over-Ear O400HA headphones provide high-quality sound and flexible listening options for different situations. They offer multiple modes: music mode for balanced audio reproduction, Hybrid Active Noise Cancelling (ANC) that reduces ambient noise by up to 35 dB, transparency mode to let important external sounds through, and a passive mode via the 3.5 mm audio jack for use without battery. The design supports both wireless and wired use and comes in several color options.
Advantages
The O400HA combines Hybrid ANC, long battery life and fast charging with an ergonomic, foldable over-ear design. Bluetooth 5.3 ensures a stable wireless connection up to 15 m, while the 40 mm drivers deliver clear and powerful sound. A wired connection is also available through the 3.5 mm jack. The package includes a USB-C charging cable and a 3.5 mm audio cable.
