Why You Should Consider Upgrading from the Plantronics CS540 to the 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.
