Poly Voyager Legend 50 UC Wireless Headset with BT700
PRODUCT DESCRIPTION
Poly Voyager Legend 50 UC Wireless Headset with BT700 (AT9M9AA) - Local Warranty
Poly Voyager Legend 50 Mono Bluetooth Headset — Full Datasheet and Specifications
The Poly Voyager Legend 50 is a single-ear (monaural) in-ear Bluetooth headset with four noise-cancelling microphones, WindSmart wind-noise reduction and Bluetooth Core 5.4, weighing just 20.5 g. The Legend 50 adds Poly NoiseBlockAI, which uses machine learning to identify and block background noise. It is built for professionals who take calls on the move and need to be understood the first time — on a worksite, in a taxi, or walking along a windy Marina Bay walkway.
Four Noise-Cancelling Microphones with WindSmart and NoiseBlockAI
Four noise-cancelling microphones on a 74.8 mm boom pick up your voice across a 100 Hz to 8 kHz band at −37 dB FS/Pa sensitivity, while WindSmart technology tames wind and airflow noise that ruins outdoor calls. Poly NoiseBlockAI adds machine-learning background-noise suppression on top, so keyboard clatter, traffic and office chatter are identified and blocked rather than merely attenuated. The result is a headset that holds up outdoors and in traffic, not just in a quiet meeting room.
Bluetooth Core 5.4, 30 m Range and Multipoint
Bluetooth Core 5.4 gives up to 30 m (98 ft) of range and multipoint, so the headset holds two devices at once from up to eight paired — typically your laptop and your phone. This SKU includes the Poly BT700 Bluetooth Type-C adapter, giving your computer a dedicated, enterprise-grade wireless link rather than relying on whatever Bluetooth radio is built into the laptop. Supported profiles are A2DP 1.3, DID 1.3, HSP 1.2, BAS 0.0, AVRCP 1.5 and HFP 1.6.
Ten Hours of Talk Time, Thirty with the Charge Case
Poly rates the Voyager Legend 50 at up to 10 hours of talk time from a rechargeable lithium-ion battery, with a full charge in under 1.5 hours over USB Type-C. This SKU includes the portable charge case, which adds a further 20 hours for up to 30 hours total away from a power point — enough for a full week of travel between charges.
Certified for Microsoft Teams, TCO Certified, Managed with Poly Lens
HP states the Voyager Legend 50 is certified for Microsoft Teams both as a USB device and over native Bluetooth, and is compatible with Zoom, Chromebook and Google Meet. The headset carries the TCO Certified ecolabel — increasingly a requirement in Singapore government and MNC procurement — and is managed through the free Poly Lens Desktop and Mobile apps for settings and firmware.

Specifications are taken from HP's published product-specification tables and the HP Poly Voyager Legend 50 Series product page for this exact part number. Figures HP does not publish for this model — standby time, IP rating, battery capacity in mAh, a quick-charge claim, Bluetooth codec support and operating temperature — have been left out rather than estimated. In particular, no IP rating is published for this headset, so we make no water or sweat-resistance claim.

USB / BYOD device mode. With the bundled BT700 adapter plugged in, the headset appears to the computer as a standard USB audio device, so any softphone or meeting client that uses the system audio device will find it — no driver install, no vendor plug-in. The supplied USB Type-C to USB Type-A adapter covers machines without a Type-C port. This is the configuration Microsoft certifies for Teams as a USB device.
Poly Lens management. Poly Lens is free and optional for a single user, and worth deploying for a fleet: it handles firmware, per-device configuration and reporting across Poly headsets and room devices from one console.

Frequently Asked Questions — Poly Voyager Legend 50
How is this AT9M9AA different from the AJ8V4AA Legend 50-M?
HP publishes identical specification tables and identical box contents for both — same headset, same BT700 Bluetooth Type-C adapter, same Qi charge case. The difference is the variant designation: AJ8V4AA is HP's “Voyager Legend 50-M Headset UC”, the Microsoft Teams variant. Order AT9M9AA for a general or mixed UC estate, and the -M version if Teams is your primary calling platform.
How does the Voyager Legend 50 compare with the Voyager Legend 30?
They share the same platform — Bluetooth Core 5.4, a 13.6 mm driver, 20.5 g, four noise-cancelling microphones, WindSmart, up to 10 hours of talk time and 30 m of range. The Legend 50 adds Poly NoiseBlockAI machine-learning noise suppression, which HP does not list for the Legend 30. If most of your calls happen in noisy environments, NoiseBlockAI is the reason to pay the difference. If you mainly need a clean, comfortable single-ear Bluetooth headset, the Legend 30 does the job for less.
Is this headset suitable for outdoor and on-the-move calling in Singapore?
That is precisely what it is designed for. Four noise-cancelling microphones plus WindSmart wind-noise reduction, plus Poly NoiseBlockAI machine-learning noise suppression target the two things that ruin mobile calls here: wind along the waterfront and open-air traffic noise. The single-ear design keeps your other ear open to your surroundings, which matters for safety when you are walking or on a site. Do note that HP publishes no IP rating for this model, so we make no claim about rain or sweat resistance.
How many hours will it actually run, and what is the charge time?
Poly rates the headset at up to 10 hours of talk time, with a full charge in under 1.5 hours over USB Type-C. This SKU includes the portable Qi charge case, which adds a further 20 hours for up to 30 hours total away from a power point.
Do I need a licence, subscription or dongle to use it?
No licence and no subscription. The BT700 Bluetooth Type-C adapter is included in the box for a dedicated computer link, and a USB Type-C to USB Type-A adapter is supplied for machines without a Type-C port. Poly Lens Desktop and Mobile are free and optional, used for settings and firmware updates; the host PC needs Windows 10 or higher to run Poly Lens.
Can I connect it to my laptop and my phone at the same time?
Yes. Bluetooth Core 5.4 with multipoint holds two connections at once from up to eight paired devices, with a range of up to 30 m (98 ft). Certification for Microsoft Teams covers both the USB-device path and native Bluetooth.
Does this headset come with a Singapore warranty and a GST invoice?
Yes. Every Poly Voyager Legend 50 sold by SourceIT comes with local Singapore warranty and a GST invoice.
