ASUS USB-BT500 Bluetooth 5.0 USB Adapter with Ultra Small Design, Backward Compatible with Bluetooth 2.1/3.x/4.x

TLDR Review: ASUS USB-BT500 Adapter

Published: March 18th, 2026

Verdict

The ASUS USB-BT500 is a solid, no-fuss Bluetooth 5.0 adapter with excellent basic compatibility and an ultra-compact design, perfect if you want a straightforward plug-and-play solution mainly for stationary uses like file transfers or single-device connections close to your PC. However, if you need longer Bluetooth range, low-latency audio, or multi-device connections, this one might leave you frustrated. For users seeking better range and multi-device support in a compact form, exploring other Bluetooth adapters with stronger wireless capabilities could be worthwhile. If Bluetooth audio latency and range are deal breakers, consider looking for an adapter that emphasizes better audio performance and extended range, although we currently only have detailed info on this model.

Top pro:
Supports Bluetooth 5.0 with backward compatibility for older Bluetooth versions, ensuring wide device support.
Top con:
Bluetooth range is quite limited, typically cutting out within 8 to 10 feet line of sight—significantly shorter than many competing adapters or direct phone connections.
