Why Upgrade from the Plantronics CS540 to HP Poly Savi 8445

Introduced in 2011, the Plantronics CS540 quickly became a go-to choice for desk phone users, replacing the highly popular CS50. Over the years, it has remained a top seller thanks to its lightweight design, reliable performance, and ease of use. However, as technology advances and workplace demands evolve, the CS540’s limitations—particularly its short battery life—are becoming more apparent.

Organizations operating on 8-hour shifts or running 24/7 operations often face challenges with the CS540’s limited 2-4 hours of real-world talk time. For such use cases, the upgraded HP Poly Savi 8445 3-in-1 Convertible Headset System is an excellent replacement, offering improved battery performance and enhanced connectivity, features, and wireless range.

Why Consider Upgrading to the Poly Savi 8445?

Enhanced Battery Life

CS540: Provides up to 7 hours of talk time but often less in real-world usage.
Savi 8445: Offers up to 13 hours of talk time and includes a hot-swappable battery, enabling uninterrupted usage for long shifts or continuous operation.

Superior Connectivity Options

CS540: Supports desk phone connectivity only. A separate cable is required for computer connectivity.
Savi 8445: Offers triple connectivity to desk phones, computers, and mobile devices via Bluetooth. This makes it an ideal choice for hybrid work environments.

Why Upgrade from the Plantronics CS540 to HP Poly Savi 8445

Greater Wireless Range

CS540: Wireless range up to 120 meters in open areas.
Savi 8445: Wireless range up to 180 meters in open areas and 55 meters in typical office environments.
