5 Recommended Popularity Rankings for Bluetooth Adapters

Bluetooth is very convenient because it is installed in smartphones and PCs and can be wirelessly connected to earphones and keyboards. However, some computers and devices may not have Bluetooth installed. In such a case, a Bluetooth adapter for pc enables you to use Bluetooth simply by connecting to the terminal and pairing it.

However, Bluetooth adapters look very similar, so it’s easy to lose track of which one to use. Which products from various manufacturers, such as Elecom, IO Data Device, Sanwa Supply, etc., should be selected? This time, we will introduce the latest recommended popular products in 2021 in ranking format, along with how to choose a Bluetooth adapter. Please refer to it and prepare a comfortable computer environment!

What is Bluetooth?

First, let me briefly explain what Bluetooth is. Bluetooth is one of the wireless communication standards for short-range wireless communication. Bluetooth communicates using radio waves in the 2.4 GHz band and connects many things such as smartphones, earphones, personal computers, and wireless mice.

The development of Bluetooth began in the latter half of the 1990s, but it became popular in Japan in the 2000s. Entering the age of smartphones, it has become one of the indispensable technologies.

Bluetooth is often installed in smartphones and personal computers, but it may not be installed in rare cases. In such a case, the Bluetooth adapter that we will introduce will be helpful too!

How to choose a Bluetooth adapter

Bluetooth adapters look similar, and all give the same impression. However, the function is unexpectedly different, so please check how to choose it.

1. Select by Bluetooth Class

First of all, there is a “Class” in Bluetooth. This shows the strength of radio waves in stages, from Class 1 to Class 3. Since Class 1 has strong radio waves, it is possible to communicate at a distance of 100 m, Class 2 speaks within a range of 10 m, and Class 3 communicates within a range of about 1 m.

Currently, Class 1 and Class 2 are the mainstream, and there are few Class 3 ones. If you want to communicate with something far away from your office, choose Class 1, and if you only use it near your computer, Class 2 will suffice.

2. Select by Bluetooth version

Bluetooth is also evolving day by day, and there are versions. There are 1.0b to 5.0, but the ones currently popular and easy to get are 4.0 and later versions. 4.0 specializes in power saving and can operate for a very long time with a small amount of power.

Bluetooth is compatible. For example, 5.0 and 4.0 devices can be connected (communication speed, etc., will be the specifications of the lower version). However, please note that there may be an incompatibility between 3.0 and earlier versions and 4.0 and later versions.

You need to make sure you know which version of the device you want to connect to via Bluetooth.

3. Carefully choose your profile

Bluetooth has a profile. Many things can be done with Bluetooth device communication, but not all devices can use all the functions, and it is decided that each device can do it. We call it a profile.

There are numerous types of profiles,  including A2DP for stereo audio communication, BIP for still image transfer, and HFP for hands-free phone communication with headsets.

Bluetooth devices support various profiles, but they cannot be used unless both keep the shape. The Bluetooth adapter has many profiles, but please check carefully what you want to be a Bluetooth device and whether it corresponds to the profile you wish to use.
