Searching for USB Bluetooth adapters under $15 or a dependable option under $20? A small Bluetooth dongle can connect a compatible Windows PC to wireless headphones, keyboards, mice, and controllers without upgrading your computer.
Here are two budget-friendly options and what to check before buying.
1. TP-Link UB500: Best Budget Pick
The TP-Link UB500 official product page describes a compact Bluetooth adapter for compatible Windows computers. Its latest listed revision supports Bluetooth 5.4, but older revisions differ. Check the exact version before ordering.
Prices vary by marketplace and location, so compare current Amazon listings against your $20 budget.
2. ASUS USB-BT500: An Alternative Under $20
The ASUS USB-BT500 supports Bluetooth 5.0 and connects through USB-A. The official ASUS US store lists it at $19.99, leaving virtually no room for extra shipping costs.
Check its official specifications before buying. These USB Bluetooth adapters are intended for compatible computers, not every television or home theater.
Where Should You Buy USB Bluetooth Adapters Under $20?
Amazon offers product comparisons, delivery estimates, and customer reviews. AliExpress may have cheaper alternatives, but check seller ratings, shipping fees, and return policies. Manufacturer websites are useful for verifying specifications and finding drivers.
Avoid unknown dongles with vague compatibility claims.

USB-C, TVs, and Home Theater: What to Know
If your laptop only has USB-C ports, look for a compatible USB-C Bluetooth adapter or use a suitable USB-C-to-USB-A adapter.
A Bluetooth adapter for TV or Bluetooth adapter for home theater is different. To transmit television audio to wireless headphones, you generally need a Bluetooth audio transmitter compatible with your TV's audio output—not an ordinary PC Bluetooth dongle.

For everyday Windows users, the TP-Link UB500 is a sensible starting point. Compare it with the ASUS USB-BT500 before purchasing.
The best USB Bluetooth adapters under $15 aren't always the cheapest listings. Prioritize compatibility, seller reputation, warranty coverage, and the final delivered price.
