Plantronics Savi 440 Wireless Headset System
The Plantronics Savi 440 is a convertible DECT wireless headset system designed exclusively for desk phone environments. With secure, interference-free connectivity and up to 300 feet of wireless range, the Savi 440 gives you the freedom to move around your workspace while maintaining crystal-clear voice quality.
We built the Savi 440 for professionals who spend hours on desk phone calls and need reliable, all-day comfort. The convertible wearing style lets you switch between over-the-head, over-the-ear, and behind-the-neck configurations to match your preference. DECT 6.0 technology ensures your conversations stay private and free from Wi-Fi interference, while the lightweight design reduces fatigue during extended wear.
What makes the Savi 440 unique
DECT 6.0 wireless connectivity
The Savi 440 uses DECT 6.0 wireless technology, which operates on a dedicated frequency band separate from Wi-Fi networks. This means you won’t experience the dropouts or audio degradation common with Bluetooth headsets in busy office environments. Your calls remain secure and private — DECT’s encrypted connection prevents eavesdropping and interference from neighboring wireless devices.
With up to 300 feet of range, you can walk to the printer, grab a file from across the office, or step into a conference room without losing your connection. The base station maintains a strong, stable link throughout your workspace, so you’re never tethered to your desk during important calls.
Convertible wearing styles for personal comfort
We include three different wearing options in every Savi 440 package: an over-the-head band, an over-the-ear hook, and a behind-the-neck band. You can switch between styles in seconds to find what works best for your head shape, hairstyle, or daily comfort preferences.
The ultra-lightweight design weighs just 21 grams — less than a standard AA battery — so you’ll barely feel it during long calls. Soft leatherette ear cushions provide a comfortable seal without creating pressure hotspots, and the adjustable microphone boom positions perfectly for your voice.
All-day battery and quick charging
A single charge delivers up to 8 hours of continuous talk time, covering a full workday for most users. When you’re not on a call, simply dock the headset on the base station to recharge. The magnetic docking guide makes placement effortless, and the LED indicator shows charging status at a glance.
If you forget to dock overnight, a quick 20-minute charge provides up to 2 hours of talk time — enough to get you through your morning calls. We designed the Savi 440’s battery system to be forgiving and predictable, so you’re never caught without power mid-conversation.

Common questions about the Savi 440
The Savi 440 connects to most business desk phones using the included RJ-9 cable, which plugs into your phone’s headset port. It’s compatible with phones from Avaya, Cisco, Polycom, Mitel, and most other major brands.
If your desk phone doesn’t have a dedicated headset port, you may need an electronic hook switch (EHS) cable or handset lifter accessory for remote answer functionality. Check your phone model’s specifications or contact us to confirm compatibility.
No, the Savi 440 is designed exclusively for desk phone connectivity. It does not support PC or mobile device connections.
If you need to take calls from your desk phone, computer, and mobile device with a single headset, the Savi 740 offers triple connectivity with the same DECT wireless technology and wearing styles as the Savi 440.
The Savi 440 provides up to 300 feet (91 meters) of wireless range in optimal conditions. Actual range varies depending on your office layout, walls, and electronic interference.
In typical office environments with drywall partitions and standard electronics, most users maintain a strong connection throughout their floor or work area. Dense concrete walls or metal barriers may reduce range.
A fully charged Savi 440 delivers up to 8 hours of continuous talk time. Standby time extends to several days when the headset is docked between calls.
If you need power quickly, a 20-minute quick charge provides approximately 2 hours of talk time. The base station charges the headset whenever it’s docked, so most users simply dock at the end of each workday.
Yes, the Savi 440 uses DECT 6.0 wireless technology with 64-bit encryption to protect your conversations. DECT operates on a dedicated frequency band separate from Wi-Fi, making it extremely difficult to intercept or eavesdrop.
This dedicated spectrum also eliminates interference from Wi-Fi routers, Bluetooth devices, and microwave ovens that can disrupt other wireless headsets.
Yes, all three wearing accessories (over-the-head band, over-the-ear hook, and behind-the-neck band) attach and detach in seconds without tools. The headset speaker module snaps into each accessory securely.
Many users keep all three accessories at their desk and switch based on comfort preferences, hairstyle, or whether they’re wearing glasses that day.
If you exceed the wireless range, you’ll hear a warning tone indicating weak signal. Your call remains connected for a short time, giving you a chance to walk back into range before the connection drops.
The Savi 440’s 300-foot range is generous enough that most users never encounter range limits during normal office movement.
