Different Types of Bluetooth Versions: What You Want to Get


Smart Ready devices can easily combine with older devices using Bluetooth models. But they are best paired with other Smart Ready devices. This is useful for those new energy-saving microsatellites.

Bluetooth 5.0-5.2 (2016)

The last version of Bluetooth, Bluetooth 5 was released in July 2016 and is aiming to improve services for IoT devices.

Main features

Bluetooth 5 provides bandwidth of 2 Mbps. The bond also extends up to 240m. Plus, it comes with Communication Code Low Complexity (LC3). This is a new audio protocol that transfers audio data to lower bitrates without changing the quality of the message. Other notable revisions include:

Less power consumption

Increased ability to announce

Backward compatibility with Bluetooth 4 versions

Dual Audio feature allows you to attach to two different devices at the same time

Addition Slot Availability Mask (SAM) that further decreases when you block LTE


Bluetooth 5 is backwards compatible with 4 Bluetooth devices. This way you can easily use a pair of Bluetooth 4.2 earphones with a 5.0 phone.

But some newer extensions don’t work on Bluetooth 5 with 4.2 devices. An example of that is Dual Audio Bluetooth 5. It allows you to connect two pairs of headphones to one phone. Or play music from one mobile phone on two different speakers.

If your device only supports 4.2, it’s still best to go for the same version of earphones. And if you own a Bluetooth 5 phone and want to create many of its features, it’s also best to upgrade your circuits to Bluetooth 5.

For a report with a Mac connection, remember to use Bluetooth 5 in 2019 copies and up. While for Windows 10 PCs, it depends a lot on your device equipped with a Bluetooth adapter.

Power requirement

Along with other versions of Bluetooth, Bluetooth 4 has seen improvements in power consumption. However, it mostly falls in the middle of his work. Bluetooth 5 further enhances the speed and range of its transmission boosting information. As a result, devices for sending and receiving information will require less power and ultimately achieve autonomy.


The Bluetooth 4 has a lower capacity of 37 octaves and an actual data payload of only 31 octaves. On the other hand, Bluetooth message capacity goes up to 5 to 255 octets long. This means less broadcast time and transmission efficiency.

The reliability of the code along with Bluetooth 5 is increased to increase frequency jumps and the Slot Availability Mask (SAM).

Better frequency hopping means that Bluetooth 5 can use a wider selection of sequences in comparison to 12 sequences that are used by Bluetooth 4. Introduction SAM specifies when transmitting LTE data to the channel. It also helps to avoid Bluetooth devices and specific channels. These two lines reduce the signal block at the same time, thus maintaining your Bluetooth connection.

In addition to Bluetooth versions, there are other Bluetooth devices that will affect the performance of your Bluetooth headphones. Here’s a quick word about them

Bluetooth profile

Bluetooth Profiles are specific types or rules that determine how devices can be used. Now, you can delegate many tasks to your receiving set headphones. Some of them make and receive calls or direct multiplayer music. These functions will require a specific Bluetooth profile to operate correctly, so that each operator has a good understanding of what to do.

HFP (Hand-Free Profile): Calls and allows you to access phone calls such as redialing numbers, waiting calls and voice dialing

HSP (Profile Headset): allows users to make and receive calls, suspend and adjust their voice volume through headphones.

A2DP (Advanced Audio Supply Profile): Allows users to stream audio from one device to another. For examples of any cat from the keyboard, the microphone is monitored, or the microphone before the boxes.

AVRCP (Audio/Video Remote Control Profile): users of their headphones use the remote control for media playback. By this figure, pause, play, cease to play, and the track is omitted.

PBAB (Phone Book Access Profile): Allows headphones to access the user’s phone via their Guest Tell feature.

Bluetooth class

The Bluetooth control output classes and wireless Bluetooth devices are in the same range. Higher power output means longer distance. Class 1 and 2 Bluetooth devices usually include laptops and tablets. On the other hand, other smaller mobile devices fall under Class III

1.Class : 100 mW (20 dBm), 100 meters (300 ft)

2. Class : 2.5 mW (4 dBm), 10 meters (33 ft)

3. Class : 1 mW (0 dBm), 1 meter (3 ft)

To sort your Bluetooth included, you will need to acquire the most capability from its extension. So if you want to use that full width 300 foot intertwined while listening to music, you will need your phone and headphones as 1st class devices If your phone is Class 1 and your headphones are Class 2, the Nexus will only be able to return to the lower class range.

Bluetooth codec

Code is a Bluetooth software that compresses and transmits audio data in a specific format and at a specified bitrate.

Codes with higher spurs, like the Sony LDAC (990kbps), typically yield better audio. The reason for this is that more data is transmitted and less compression is performed. A key discrepancy exists in the more common SBC codex. SBC codec transmits data up to 192-320kbps and lowers sound quality.

Now both Bluetooth 4 and 5 codecs can handle even smaller items. So, upgrading to Bluetooth 5 is not a surprising way to improve the sound quality of your headphones. Learn more about this and how to use Bluetooth codes in our in-depth article.


There are two types of wireless links, but Bluetooth remains king to this day. However, the different Bluetooth versions will not only determine the brightness of our wireless sound quality. And throughout the course of each letter, they have given us a lighter report of the experience. Eventually, the sound quality is determined by a combination of products such as Bluetooth profiles, codecs and classes.
