About this headset

The Discover D904 is a DECT wireless office headset system that connects to both a desk phone and a PC or softphone over USB-A. It works with common collaboration platforms including Teams and Zoom, and ships with two batteries so one can charge while the other is in use. The convertible design lets each user choose a headband or ear-hook fit, making it a fit for all-day, high-volume calling.

Key features

  • DECT wireless connection with a base for desk phone and PC / softphone (USB-A)
  • Works with Teams and Zoom
  • Wireless range up to 91 m / 300 ft from the base
  • Up to 6.5 hours of talk time per battery, with two batteries included
  • Noise-cancelling boom microphone for clearer calls
  • Convertible wearing style (headband or ear-hook)

Certified Renewed

Every unit is electronically tested across its full call path, then professionally cleaned and sanitized. We replace the battery and any worn parts as needed, and only Grade A cosmetic units ship. Your purchase is backed by a 1-year advanced-replacement warranty plus lifetime support.
