Description:

The Fanvil DH401B OWS Bluetooth Headset combines open-ear comfort with advanced voice processing for professional calls and communications. Full-duplex technology supports natural two-way conversations, while AI ENC helps reduce environmental noise and AEC helps minimise acoustic echo during calls. The two omnidirectional analogue microphones provide accurate voice pickup without requiring the headset to fully cover the ear.

Bluetooth 5.4 multipoint connectivity allows the DH401B to remain connected to multiple devices, making it suitable for users who regularly move between a computer and mobile phone. The rechargeable lithium polymer battery provides up to 5 hours of talking time from the headset, while the charging case extends total talk time to up to 23 hours.

Features:

Fanvil DH401B Bluetooth Headset for Professional Communication
The open-ear wireless design is particularly useful in offices, reception areas, transport environments and other situations where users need to communicate while remaining aware of what is happening around them. At just 13.6 g, the ear-hook construction is designed for comfortable extended use without the bulk of a conventional headset.

Key communication and connectivity points include:

• Open-ear OWS design for situational awareness and comfortable daily use
• Two omnidirectional analogue microphones for accurate voice pickup
• AI environment noise cancellation (AI ENC) for clearer conversations
• Acoustic echo cancellation (AEC) to help reduce unwanted echo
• Full-duplex technology for natural two-way communication
• Bluetooth 5.4 with multipoint connectivity
• Compatible with LINKVIL portable phones and Fanvil VoIP phones
• 13.6 g lightweight ear-hook design
• Rechargeable lithium polymer battery
• Approximately 2 hours charging time
• Up to 5 hours talking time from the headset
• Up to 23 hours total talk time when used with the charging case

Open-Ear Bluetooth Headset with AI Noise Cancellation
For users working in environments where background sound cannot always be avoided, the DH401B uses AI environment noise cancellation to help improve voice clarity. Acoustic echo cancellation works alongside the microphone system to provide cleaner conversations, while full-duplex technology supports simultaneous two-way audio.

The open-ear format also means users do not need to completely block their ears. This makes the headset well suited to office workers, mobile professionals and anyone who needs to remain aware of surrounding conversations or activity while taking calls.

Bluetooth 5.4 Multipoint Connectivity
Bluetooth 5.4 provides a modern wireless connection with convenient multipoint support. Users can connect the DH401B to a phone and PC and switch between devices as required, reducing the need to repeatedly disconnect and pair the headset.

Its compatibility with LINKVIL portable phones and Fanvil VoIP phones makes it a useful option for businesses already using Fanvil communication equipment.

Battery Life and Charging
The rechargeable lithium polymer battery provides up to 5 hours of talking time from the headset, with a charging time of around 2 hours. When combined with the charging case, total talk time can reach up to 23 hours, providing additional flexibility for users who spend much of the day handling calls away from a desk.

Lightweight Design for Everyday Use
Weighing only 13.6 g, the DH401B is designed for users who need a wireless headset that can be worn comfortably during extended conversations. The ear-hook design helps keep the headset securely positioned without relying on a traditional headband.

The product is supplied under Part Number / SKU FAN-DH401B, making it easy to identify when ordering, quoting or specifying the correct Fanvil headset.
