Bluetooth Adapter Selection Guide: Transform Old Devices into Wireless in an Instant
A USB device can free your desktop computer from the constraints of cables.
Have you ever been troubled by your desktop computer being unable to connect to a Bluetooth headset? Do you think the Bluetooth function of your old laptop is too weak and it often disconnects?
The Bluetooth adapter is precisely the "wireless translator" that solves these problems. It enables devices without Bluetooth functionality to smoothly connect to various Bluetooth peripherals.
01 Why do we Need a Bluetooth Adapter
A Bluetooth adapter is essentially a USB plug-in device that adds Bluetooth functionality to a computer. It is specifically designed to connect Bluetooth headphones, speakers, mice, keyboards and other devices to desktops or old laptops without Bluetooth functionality.
Especially the older models of computers around 2015, although still performing well, were often "isolated" from the wireless world due to the lack of a Bluetooth module.
It is like a key that opens the door to wireless communication for old computers, allowing you to enjoy the refreshing experience of "listening to music without a rope and typing without wireless".
02 Key Purchasing Parameters
Bluetooth version
The Bluetooth version directly determines the performance and compatibility of the adapter.
The current mainstream choice is Bluetooth 5.3 and higher versions. They not only have a faster transmission speed, but also have a longer connection distance and higher stability.
All Bluetooth versions support backward compatibility. However, if you use a high-version Bluetooth device (such as a Bluetooth 5.3 headset) with a low-version adapter (such as Bluetooth 4.0), after connection, you can only use the low-version Bluetooth protocol and cannot achieve high performance.
Therefore, it is recommended to purchase a higher version of the Bluetooth adapter as much as possible.
Transmission distance and stability
Transmission distance is one of the important indicators for measuring the performance of a Bluetooth adapter.
Class 1 device: The transmission distance can reach over 100 meters, making it suitable for large Spaces or office environments
Class 2 device: The transmission distance is approximately 20 meters, which is suitable for general household use
Low-power Bluetooth adapters can reduce energy consumption and extend usage time.
03 Different Needs Selection Strategies
Select according to the usage scenario
Students/office workers: Pursuing cost performance + compact portability.
Audio and video enthusiasts/gamers: Emphasize low latency and high sound quality.
Home entertainment center: Multiple devices need to be connected simultaneously.
We recommend an adapter with multi-point connection function to easily create a wireless audio-visual center in the living room.
Select by peripheral type
Connect the audio system, headphones, keyboard, mouse and printer
