Poly Savi 8445 UC Office Convertible Wireless DECT Headset
PRODUCT DESCRIPTION
Poly Savi 8445 UC Office Convertible Wireless DECT Headset (2-221107-205 / 8L5B4AA) - Local Warranty
Poly Savi 8445 Office 3-in-1 Convertible DECT Wireless Headset
The Poly Savi 8445 Office is the convertible model in HP's Savi 8400 DECT range. At 21 g worn over the ear it is by far the lightest headset in the series, and the supplied convertible fit kit lets the same part number be worn over the head, over the ear or behind the neck. One SKU therefore suits an entire floor of users with different preferences.
Savi 8445 Specifications: Unlimited Talk Time with a Hot-Swappable Spare Battery
HP specifies up to 13 hours of talk time on a single charge, and the Savi 8445 ships with a spare battery plus a USB deluxe charger — which is why the official Poly datasheet rates this model for unlimited talk and standby time. Swap the battery mid-shift and the headset never leaves the user's ear. Recharge takes less than three hours on a rechargeable Li-ion polymer cell.
Secure DECT on 1880-1900 MHz with 180 m Roaming Range
The Savi 8445 runs DECT on 1880–1900 MHz with Bluetooth v5.2 for the mobile connection, and HP rates the range at up to 590 ft / 180 m line of sight, or up to 180 ft / 55 m in a typical office. HP lists the headset as DECT security certified.
Three-Way Connectivity and All-Day Hearing Protection
The Office base connects your desk phone, computer and Bluetooth mobile at the same time. The noise-cancelling microphone with close conversation limiting keeps the open-plan floor off your calls, SoundGuard DIGITAL protects against sound levels above 118 dBA, and up to four headsets can be conferenced onto one base.

Frequently Asked Questions — Poly Savi 8445
Is this the Microsoft Teams version?
No. This is the UC (unified communications) build. HP publishes a separate Teams-certified part number for the same headset — Savi 8445-M MS Office Convertible.
Which Savi 8400 model should I choose — 8410, 8420 or 8445?
The Savi 8410 is a monaural (single-ear) headset weighing 115 g, so you stay aware of the room. The Savi 8420 is the stereo model at 160 g and is the only Savi 8400 that adds active noise cancelling. The Savi 8445 is the 3-in-1 convertible at 21 g worn over the ear, and it ships with a hot-swappable spare battery for unlimited talk time.
Does the Poly Savi 8445 have active noise cancelling?
No. HP specifies active noise cancelling on the Savi 8420 stereo model only. The Savi 8445 does carry the series noise-cancelling microphone with close conversation limiting, which keeps your voice clean for the person on the other end in an open-plan office.
How far can I walk from the base while on a call?
HP rates the Savi 8400 Office Series at up to 590 ft / 180 m line of sight, and up to 180 ft / 55 m in a typical office with walls and partitions — comfortably the length of most Singapore office floors.
Do I need a compute appliance, licence or dongle for this headset?
No. The Office base is the receiver, and it is included. There is no separate licence or room PC. You plug the base into your computer with the supplied USB Type-A or USB Type-C cable, and into your desk phone with the supplied telephone interface cable. A separate Savi DECT USB dongle is only needed for the dongle-based Savi models, not for this Office system.
Can colleagues join a call on the same base?
Yes. HP specifies that up to four headsets can be conferenced together on a single Savi 8400 Office base, which is useful for training, call listening and side-by-side coaching.
What does the 3-in-1 convertible design mean?
The Savi 8445 ships with a convertible fit kit so the same 21 g headset can be worn over the head, over the ear or behind the neck. Users pick the wearing style that suits them without you having to stock three different part numbers.
Does the Poly Savi 8445 come with warranty in Singapore?
Yes. Every Poly Savi 8445 sold by SourceIT comes with local Singapore warranty and a GST invoice.
