PRODUCT DESCRIPTION
Poly Savi 8445-M MS Office Convertible Wireless DECT Headset (2-221108-205 / 8L5B6AA) - Local Warranty
Poly Savi 8445-M Microsoft Teams Certified 3-in-1 Convertible DECT Headset
The Poly Savi 8445-M Office is the Microsoft Teams certified build of HP's convertible Savi 8400 DECT headset, published by HP as the "Savi 8445 Office Microsoft Teams Certified DECT 1880-1900 MHz Convertible Headset". At 21 g worn over the ear it is the lightest model in the series, and it is the SKU to order when Teams certification is a procurement requirement.
Savi 8445-M Specifications: 32 mm Speaker, Unlimited Talk Time, 180 m Range
HP publishes a full specification table for this part number: a 32 mm speaker rated at 118 dB SPL with a 100 Hz – 6.8 kHz wideband response, a noise-cancelling microphone at 112 dB SPL, DECT on 1880–1900 MHz, Bluetooth Core 5.2, a rechargeable Li-ion polymer battery charging in under three hours, and unlimited talk and standby time thanks to the supplied hot-swappable spare battery.
Wear It Three Ways — One Part Number for the Whole Floor
The convertible fit kit ships in the box, so the same headset can be worn over the head, over the ear or behind the neck. That removes the need to stock separate mono, stereo and over-the-ear part numbers for a mixed team, which simplifies procurement for larger Singapore rollouts.
Broad Platform Support and Three-Way Connectivity
HP lists support for Windows 11, Windows 10, macOS, Android and iOS with A2DP, HFP and HSP Bluetooth profiles. The Office base keeps the desk phone, computer and mobile connected at once, up to four headsets can be conferenced on one base, and SoundGuard DIGITAL protects against sound levels above 118 dBA.

Frequently Asked Questions — Poly Savi 8445-M
What is the difference between the Savi 8445-M-M (MS) and the Savi 8445-M UC version?
They are the same headset hardware. The -M part number is the Microsoft Teams certified build, which HP lists as Certified for Microsoft Teams. The UC part number is the general unified-communications build. Choose the -M SKU if your organisation standardises on Teams certification: see the Savi 8445 UC 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-M have active noise cancelling?
No. HP specifies active noise cancelling on the Savi 8420 stereo model only. The Savi 8445-M 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-M come with warranty in Singapore?
Yes. Every Poly Savi 8445-M sold by SourceIT comes with local Singapore warranty and a GST invoice.
