Plantronics Savi 8240 Wireless Headset System
The Plantronics Savi 8240 wireless headset system is our premium convertible DECT solution for professionals managing calls across desk phone, PC softphone, and mobile devices simultaneously. We built this system with active noise canceling (ANC) technology that adapts to your environment in real time, reducing background noise by up to 43 dB so your voice stays clear on every call.
Unlike consumer Bluetooth headsets that sacrifice range and security, the Savi 8240 runs on enterprise-grade DECT wireless, giving you up to 590 feet of roaming freedom from the base station with zero interference from Wi-Fi networks. Our convertible wearing style lets you swap between over-the-head and over-the-ear configurations in seconds, so the headset adapts to your workday instead of forcing you into one fit.
We designed the base station with a high-resolution display that shows connection status, battery life, and active audio source at a glance. The system ships with a charging cradle that holds the headset and spare battery, ensuring you never lose a call to a dead battery mid-conversation.
Wireless connectivity & audio specs
Triple-device connectivity for hybrid workflows
The Savi 8240 connects to three audio sources simultaneously through the base station: your desk phone via RHL-10 handset lifter or EHS cable, your computer through USB, and your smartphone via Bluetooth 5.0. We engineered the system so you can answer calls from any connected device without removing the headset or fumbling with manual switches.
When a call comes in on your desk phone while you’re on a PC meeting, our smart call management detects the incoming call and lets you swap devices with a single press of the multifunction button on the headset. The base station handles call prioritization automatically, so urgent calls on your primary line always break through. This makes the Savi 8240 a practical upgrade for professionals who split time between VoIP platforms, traditional PBX systems, and mobile devices throughout the day.
Active noise canceling and acoustic clarity
We built the Savi 8240 with adaptive active noise canceling that monitors ambient sound 15,000 times per second and adjusts suppression levels in real time. Whether you’re working from a quiet home office or a busy open-plan workspace, the ANC circuitry isolates your voice and reduces background chatter, keyboard noise, and HVAC hum by up to 43 dB before it reaches the microphone.
Wideband audio and SoundGuard DIGITAL
The headset delivers wideband audio (150 Hz to 6,800 Hz) for natural voice reproduction that captures the full tonal range of human speech. We paired this with our SoundGuard DIGITAL technology, which protects against acoustic shock by limiting sudden loud sounds to 118 dBA and maintaining average exposure below 85 dBA over an eight-hour shift. Every unit ships G616 certified, meeting hearing protection standards for enterprise telecom environments.
Convertible wearing styles and all-day comfort
The Savi 8240 ships with both over-the-head and over-the-ear wearing options in the box. Our convertible frame lets you snap the headband off and attach the ear loop in under ten seconds without tools, so you can switch configurations between calls or match your wearing preference to the task at hand.
We designed the leatherette ear cushion with memory foam that molds to your ear shape over the first few wears, distributing pressure evenly to prevent hotspots during long shifts. The adjustable headband uses a spring-steel core wrapped in soft-touch rubber, so it stays secure during movement without creating a clamp-force headache. At 21 grams for the headset alone, the Savi 8240 weighs less than most over-the-ear models while delivering over-the-head stability when you need it.

Questions about the Savi 8240 system
The Savi 8240 delivers up to 590 feet of DECT wireless range in open-space environments. Actual range depends on building construction and interference sources, but in typical office settings you can expect 300 to 400 feet of reliable coverage, which covers most floor plans including conference rooms, break areas, and private offices.
DECT operates on a dedicated frequency band separate from Wi-Fi, so you won't experience dropouts when walking past wireless access points or microwave ovens. The base station display shows real-time signal strength, and the headset alerts you with a tone when you approach the edge of range before the connection drops.
Yes, the Savi 8240 connects to most desk phones through either a mechanical handset lifter (RHL-10, sold separately) or an electronic hook switch (EHS) cable specific to your phone model. The handset lifter physically raises your desk phone handset when you answer a call on the wireless headset, while the EHS cable integrates electronically with compatible phone models for cleaner remote call control.
We support desk phones from Avaya, Cisco, Polycom, Mitel, and other major PBX manufacturers through our range of EHS cables. Check the Plantronics compatibility guide or contact our support team with your desk phone model number to confirm which accessory you need.
The Savi 8240 ships with two lithium-ion batteries: one installed in the headset and one stored in the charging bay on the base station. When your active battery drops to 10%, the headset announces remaining talk time in your ear.
To swap batteries mid-call, slide open the battery door on the headset, pull out the depleted battery, and snap in the charged spare from the base. The headset maintains your active call during the swap as long as you complete the exchange within 30 seconds. Drop the depleted battery into the base charging bay, and it will be fully charged in about 90 minutes for your next swap.
The Savi 8240 is our convertible model that ships with both over-the-head and over-the-ear wearing options, giving you the flexibility to switch styles without buying a second headset. The 8220 is a fixed dual-ear (stereo) design for users who want maximum immersion and noise isolation. The 8210 is a fixed monaural (single-ear) headset for professionals who need to hear their surroundings, like receptionists or workers in shared spaces.
All three models share the same DECT base station, triple connectivity, active noise canceling, and battery system. Your choice comes down to whether you want convertible flexibility, dual-ear immersion, or monaural environmental awareness.
Yes, the Savi 8240 is a standards-based USB audio device that works with all major UC platforms including Zoom, Cisco Webex, RingCentral, Google Meet, GoToMeeting, and 8×8. The dedicated Teams button is a shortcut for Microsoft Teams users, but it doesn't prevent the headset from working with other apps.
When you're on a Zoom call, you can still use the multifunction button on the headset boom to answer/end calls and mute/unmute. The headset shows up as a standard audio device in your operating system, so any application that supports USB headsets will recognize and control the Savi 8240 through its native call controls.
Firmware updates are delivered through our free Plantronics Hub software for Windows and macOS. Install Hub on your computer, connect the Savi 8240 base station via USB, and the software will automatically detect available firmware updates for both the base and headset.
Hub walks you through the update process, which typically takes 5 to 10 minutes and requires the headset to be docked on the base during installation. We release firmware updates to add UC platform support, improve battery performance, and fix bugs, so we recommend checking for updates quarterly or whenever you experience unexpected behavior.
The Savi 8240's active noise canceling operates automatically and adapts to your environment in real time without manual adjustment. The ANC circuitry continuously monitors ambient noise through dedicated microphones and applies suppression as needed to maintain clear outbound audio.
You can't disable ANC on the 8240, as it's integrated into the microphone signal path to ensure call clarity. If you prefer a headset without ANC for specific work environments where you need to hear background sounds naturally, consider the Savi 8210 monaural model, which offers environmental awareness through its single-ear design.
