Description

The Pro SP325 is the wired sibling of Dell's SL525: same 125mm round body and four omni-directional MEMS microphones, but with an integrated 75cm USB-C cable instead of a battery and Bluetooth radio. Nothing to charge, nothing to pair and no dongle to lose — plug it in and it works.A 60mm dynamic driver gives 3.2W RMS and an 82dB peak, with a 90Hz to 20kHz response in music mode and 100Hz to 14kHz for speech. The microphone array covers roughly 2.5 metres and runs Dell's dual-directional AI noise cancelling with full-duplex DSP and echo cancellation, so both ends of a call can talk at once without clipping.It is driver-free across Windows 10 and 11, macOS, ChromeOS, Linux and Ubuntu 24.04, and certified for Microsoft Teams and Zoom. A USB-A adapter is supplied for older machines. The IP64 rating makes it dust-tight and splash-resistant, which suits a shared hot desk or a kit bag. Cover is a three-year limited warranty.
