Poly recommends the adapter for supported headset connections and call features, but that is not proof of lower audio delay. If your built-in Bluetooth works reliably and you do not need Poly-specific functions, the documents do not establish a latency reason to switch.
What the BT700 documentation does—and does not—say about latency
The reviewed sources provide no BT700 latency figure, controlled comparison with built-in Bluetooth, or test method. That means there is no documented basis for saying the adapter makes audio “instant,” reduces delay by a particular number of milliseconds, or is a gaming low-latency solution.

For the Voyager Focus 2, Poly says the USB adapter provides the “best connection, softphone functionality and acoustic sound quality through your headset.” That is manufacturer guidance about connection and features, not a measured latency claim. HP’s BT700 USB-A specifications likewise list compatibility and Bluetooth profiles, not delay measurements.
When the Poly adapter may be the better choice
The BT700 is a supported way to connect compatible Poly headsets to a PC and access the manufacturer’s intended PC integration. Poly’s Voyager Focus 2 guide covers adapter connection, media-device configuration, and Poly Lens setup. A separate HP support guide for pairing a Voyager 5200 says Poly Lens Desktop App is required to pair a BT700 to a Poly audio device.

Poly’s 2020 technical tip on the older BT600 describes controlled PC/headset pairing, wideband audio support, call controls, and Poly software. Those are feature benefits stated by the manufacturer; they do not demonstrate lower latency, and BT600 compatibility should be checked against the specific headset.
- Choose the adapter when your particular Poly headset is supported and you need its documented call-control, softphone, or Poly software behavior.
- Built-in Bluetooth can be adequate if it connects reliably and you do not need those adapter-specific functions.
- Do not assume a generic Bluetooth adapter will reproduce Poly’s integration features.
Check the exact adapter and connection before buying or switching
HP’s regional Middle East listing for the BT700 USB-A (786C4AA) specifies PC USB-A compatibility, Windows and macOS support, and A2DP, AVRCP, and HSP profiles. This identifies that listed USB-A variant; it does not establish compatibility for every computer, headset, adapter connector variant, or software configuration. Confirm the exact headset and adapter model before relying on the listing.

The Voyager Focus 2 guide identifies BT700 and BT700C adapter variants and describes the adapter as typically pre-paired. For pairing it with another supported Poly audio device, the guide directs users to Poly Lens Desktop App. For media playback, it says to configure the adapter and select Poly BT700 as the input and output device where applicable.

Late-starting audio, video that falls out of sync, dropped calls, incorrect input/output selection, and missing call controls are different symptoms. The reviewed documents do not diagnose a BT700 latency defect or establish the adapter as a fix for audio delay. Before changing hardware, identify the headset model, computer and operating system, app, connection mode, and the specific symptom.

If you use a Voyager Focus 2 and call dropouts appear related to Bluetooth density, Poly’s guide recommends a wired test: disconnect the Bluetooth adapter, connect the headset directly to the computer with its USB cable, and power off the headset for corded mode. This is a troubleshooting option for reliability in that scenario—not evidence that wired mode or the adapter has a measured wireless-latency advantage.

How to decide
- Need Poly call integration: Use the BT700 or the compatible adapter specified for your headset, and follow the headset’s Poly Lens setup instructions.
- Built-in Bluetooth is stable and feature needs are basic: There is no sourced latency comparison that justifies switching solely to reduce delay.
- Calls drop in a crowded radio environment with a Voyager Focus 2: Try the guide’s corded-mode procedure to test whether reliability improves.
- Need a proven latency advantage: The available manufacturer documentation does not establish one. A valid comparison would need to test the exact headset, host, software, Bluetooth profile or codec, and workload.
