Can I connect different Bluetooth versions?

I have earphones.

This is Bluetooth 3.0.

I bought a new cell phone this time, but I haven't received it yet, but it has Bluetooth 4.0.

Will Bluetooth 3.0 and Bluetooth 4.0 be compatible and connected?

You can use it even if the two products you want to connect through Bluetooth are different versions.
The performance will be adjusted to the lower version.
So the speed will be adjusted to version 3.0.

There are currently 4.0 versions of Bluetooth.
In fact, the most commonly used versions of Bluetooth devices are 2.0, 2.1+EDR.
With the latest Bluetooth machine, it would not have disabled existing Bluetooth devices.

Bluetooth 3.0 has a transmission speed of 24 Mbps
Bluetooth 4.0 is a technology that focuses on reducing power consumption and making the product smaller, so the transmission speed is 1 Mbps.
Usually, if the version is different, it fits the lower version
Bluetooth 4.0 is slower than 3.0, so it might work faster kk
