IHDAPP Z3#Q2521_B Bluetooth 5.3 Adapter

The IHDAPP Z3#Q2521_B adds Bluetooth 5.3 to a PC or laptop through a standard USB port. It targets users who want to connect wireless headsets, speakers, keyboards, mice or phones without opening the case. The adapter uses a Realtek chip that complies with the Bluetooth 5.3 specification and supports dual-mode low-power transmission.

The adapter delivers up to 3 Mbps data throughput and an unobstructed range of 10 to 20 metres. It can maintain simultaneous connections with up to seven Bluetooth devices such as headsets, speakers and input peripherals. Actual range and speed will drop with walls, interference or when multiple devices share the available bandwidth.

Installation and common issues
