Description

Dell SL525 Universal Black is a wireless USB-C speakerphone designed for hands-free communication in small meeting spaces, home offices and mobile setups. The unit integrates an omnidirectional microphone array and an 8 W dynamic driver to reproduce voice with a frequency response that supports clear speech. It offers Bluetooth wireless connectivity alongside wired USB-C connection, a 3200 mAh rechargeable battery and an operating range of up to 30 m, providing portable use and extended talk time for calls and conferences.

Advantages

The speakerphone provides up to 12 hours of continuous talk time on a single charge and supports fast, reliable connections via USB-C or Bluetooth. Its omnidirectional microphone design captures voices from all directions, while an 8 W driver and 86 dB sensitivity ensure audible playback for small groups. The compact, cordless form factor and multi-microphone voice pickup simplify setup and reduce the need for additional audio equipment.
