Product information

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.

How to use

Charge the headphones via the USB-C port until fully charged (about 2 hours) or use quick charge for 15 minutes to get roughly 6 hours of playback. Pair the headphones with a Bluetooth 5.3 device following standard pairing steps or connect a device directly using the 3.5 mm audio cable for passive mode. Switch between music, ANC, and transparency modes using the on-device controls to suit your environment. Fold the adjustable headband for compact storage and transport.

Recommendations

For the best ANC performance, ensure a snug fit over the ears and keep firmware up to date if updates are provided. Use the 3.5 mm cable when battery-free operation is required. Store the headphones in a dry place and avoid exposure to extreme temperatures to maintain battery health.
