Plantronics Savi 8240 Wireless DECT Headset System
Our Plantronics Savi 8240 is a convertible wireless headset system built for professionals who need secure, interference-free audio across desk phone, PC, and mobile devices. The DECT wireless technology delivers 590 feet of roaming range and up to 13 hours of talk time on a single charge, so you stay connected whether you’re at your desk or moving between conference rooms.
The convertible design lets you switch between over-the-head, over-the-ear, and behind-the-neck wearing styles in seconds, adapting to your workday without compromising call quality. We engineered the Savi 8240 with three-way connectivity—desk phone, computer softphone, and mobile via Bluetooth—so every call routes through one headset and one intuitive base station.
What’s included with your Savi 8240

DECT Wireless Technology & Security
The Savi 8240 operates on DECT 6.0 wireless frequency, a dedicated spectrum separate from Wi-Fi and Bluetooth, eliminating the audio dropouts and interference common in busy office environments. This same secure protocol is used in enterprise telephony systems worldwide, delivering encrypted audio streams that meet compliance standards for finance, healthcare, and government verticals.
DECT also enables adaptive power management—our base station automatically adjusts signal strength based on your distance, preserving battery life when you’re nearby and boosting range when you roam. The result is consistent call quality whether you’re 10 feet or 500 feet from your desk, with no manual pairing or dropouts during handoffs between rooms.

Convertible Wearing Styles for All-Day Comfort
We designed the Savi 8240 with three interchangeable wearing options because no two professionals work the same way. The over-the-head style distributes weight evenly and works well for users who wear the headset continuously throughout the day. The over-the-ear hook offers a lightweight, low-profile option ideal for alternating between headset and handset calls.
The behind-the-neck band keeps hair and glasses free while maintaining secure placement during movement. All three styles use the same quick-release connector, so you can swap configurations in under 30 seconds without tools. The leatherette ear cushions are replaceable and available in standard or large sizes to match your ear geometry.
Three-Way Connectivity & Call Management
Our Savi 8240 base station handles simultaneous connections to your desk phone via RJ-9 or electronic hook switch cable, your computer via USB for softphone applications, and your mobile device via Bluetooth 5.0. When a call comes in on any line, the base station’s visual indicators show the source, and you answer with a single press of the headset’s call control button.
Seamless Device Switching
You can hold a call on one device and switch to another mid-conversation—put a PC call on hold to take an incoming mobile call, then return to the original without disconnecting. The base station remembers up to eight Bluetooth devices, making it simple to share the system across personal and work phones. For teams using the same Savi platform across multiple models, the standardized base and connectivity architecture simplifies IT deployment and reduces training overhead.

Common Questions About the Savi 8240
The Savi 8240 base station uses three separate connection methods running in parallel. Your desk phone connects via an RJ-9 cable or electronic hook switch adapter, your computer connects through the USB port for softphone applications, and your mobile device pairs via Bluetooth 5.0. All three connections remain active at once, and the base station’s intelligent call routing lets you answer, switch, or hold calls from any source using the headset’s single call control button.
The base displays visual indicators for each active line, so you always know which device is ringing or in use.
The DECT 6.0 wireless technology in the Savi 8240 delivers up to 590 feet of range in line-of-sight conditions. In real-world office environments with walls, cubicles, and electronic equipment, you can typically expect 300 to 400 feet of reliable coverage depending on construction materials.
DECT operates on a different frequency than Wi-Fi and Bluetooth, so congested wireless networks won’t reduce your effective range. The base station uses adaptive power management to maintain clear audio whether you’re at your desk or roaming between conference rooms.
Yes, the convertible design specifically accommodates glasses wearers. The over-the-ear and behind-the-neck options sit away from your temples, eliminating pressure points where glasses arms rest. You can switch between all three wearing styles—over-the-head, over-the-ear, and behind-the-neck—without tools by releasing the quick-disconnect on the headband and snapping in your preferred style.
Many users keep two configurations at their desk and swap based on the type of work—for example, using over-the-head for long conference calls and switching to behind-the-neck for mixed tasks involving handset calls.
The included lithium-ion battery provides up to 13 hours of continuous talk time or 50 hours of standby on a full charge. Recharge time in the base station is approximately three hours from empty to full. For extended shifts or 24/7 operations, the optional spare battery enables hot-swapping—you remove the depleted battery and insert the charged spare while on an active call without disconnecting.
Both the primary and spare batteries slide in and out of the headset without tools, and the base station includes a secondary charging bay for keeping your spare ready.
Yes, the Savi 8240 is Microsoft Teams certified and supports call control integration including answer, end, mute, and volume adjustment directly from the headset. It also works with Zoom, Cisco Webex, RingCentral, Avaya, and other major unified communications platforms through standard USB audio protocols.
When using softphone applications, the base station’s USB connection provides plug-and-play compatibility with both Windows and macOS without driver installation. Your UC app recognizes the Savi 8240 as the default audio device and routes all calls through the headset automatically.
DECT wireless uses dedicated spectrum in the 1.9 GHz band with 128-bit encryption on every audio stream, meeting security standards for HIPAA, PCI DSS, and government communications. Because DECT operates separately from Wi-Fi and Bluetooth, your headset traffic is isolated from network-based attacks or eavesdropping tools that target 2.4 GHz devices.
The base station and headset authenticate using unique pairing keys that prevent unauthorized headsets from connecting to your base. For enterprise deployments, DECT also eliminates the Bluetooth discoverability window that can expose devices to reconnaissance scanning.
While the base station can remember up to eight Bluetooth mobile devices, the DECT headset pairing is one-to-one for call quality and security reasons—one headset pairs to one base station at a time. For shift-based teams sharing workstations, we recommend either assigning each user their own headset that they take between stations, or deploying individual base stations per workstation with headsets that remain at each desk.
The hot-swap battery feature does enable continuous operation across shifts when a single user needs 24-hour coverage, but we don’t support multiple headsets actively sharing the same base during overlapping shifts.
