Bluetooth has the concept of “Class.” Even with the same Bluetooth product, the strength of the radio wave differs depending on the class that is certified. That is, the communicable distance also changes.
Before you buy a Bluetooth product, make sure that you have the required class before purchasing so that it does not say, “The radio wave did not reach …”. There are three types of Classes 1-3.
One thing to keep in mind when choosing a product is that Class 1 devices do not always reach the maximum communication distance of 100m. For example, earphones with a communication distance of 20 m and microphones with a range of 50 m are also classified in Class 1. In other words, if the maximum output is “more than Class2 and within 100mW”, they are all equally classified into Class1.
As described above, even if the products are of the same class, the communication distance varies. If you want to focus on range, check the maximum output for each product.
Also, the intensity of radio waves that can be output differs depending on the country or region where the device is used. The upper limit is about 50 mW under the Japanese Radio Law, but not overseas. Besides, keep in mind that the distance may fluctuate depending on the performance of the receiving antenna and power amplifier, so it cannot be measured unconditionally.
Hold down the “power” button or “PAIRING” button on the headphones until the lamp on the central unit blinks (about 7 seconds).
There are the following two patterns for the lamp blinking.
The blue lamp blinks twice each time
Blue and red lights flash alternately
Refer to the instruction manual as it varies depending on the model.

* If you are asked for a passkey, enter “0000 (Zero Zero Zero Zero)”.
A passkey is sometimes called a passcode, PIN code, PIN, password, etc.
The pairing is completed.
NOTE: If you see an authentication error, it’s too long. Move the device closer and try pairing again.
