The Creative BT-W2 is a USB Bluetooth transmitter. It serves as a small but powerful device that "upgrades" the Bluetooth capabilities of the PC/Mac or even Play Station 4 that it is plugged into. It instantly provides the host device with low-latency aptX Bluetooth capabilites for a more seamless wireless experience. The BT-W2 transmitter also allows for two-way transmission of audio and voice, a feature not available on many PCs/Macs, and this allows users to fully utilize their Bluetooth headsets' voice capabilities with the host device.
