Conference Speaker Dell Pro Plus Wireless Speakerphone SL525 520-BBMZ

Dell Pro Plus Wireless Speakerphone SL525 - Professional Conferencing Audio

The Dell Pro Plus SL525 is a wireless speakerphone built for video meetings and group calls at home and in the office. It combines omnidirectional microphones, AI-based noise cancellation and flexible connectivity - wirelessly via a dedicated receiver or Bluetooth, or wired straight over USB-C. The result is clean, intelligible audio on both ends, regardless of the room or background noise.

Clear voice in every meeting

At the heart of the device are omnidirectional digital MEMS microphones with a pickup range of up to 2.5 m and a high signal-to-noise ratio. The AI-based noise-cancelling algorithm filters out keyboard clatter, air conditioning and side conversations so speakers come through clearly. The unit is certified for Microsoft Teams and Zoom, with a dedicated Teams button for one-touch access.

Wireless, portable and self-contained

The speakerphone connects wirelessly through a dedicated Dell audio receiver or via Bluetooth 5.3 with multipoint support for two simultaneous sources. An internal rechargeable battery delivers up to 12 hours of talk time, and the device ships with a travel pouch and a USB-A adapter, so it travels easily to any meeting room or home desk. The control surface includes mute, volume and answer/end-call keys with clear status indicators.

Management and tuning

Using Dell Display and Peripheral Manager you can update firmware and fine-tune audio settings. Connection is plug-and-play and compatible with a wide range of Computers and operating systems, making it a simple, immediate solution for high-quality conference calls.
