It is incorrect to compare a radio headset with Bluetooth and wired headphones. It was created for long-term comfortable wearing and communication at the PC. It has no audio delays (unlike Bluetooth) and no wires. You can switch to Bluetooth for some home purposes (call or watch TV at night), but using it on the street is a very controversial activity, because the headset is not foldable, easily soiled, without a case in the kit and there are no buttons to control music. Below I will add instructions for managing, someone may come in handy. On/Off button: One press: Indicates the battery level. When the indicator is green, you have approximately 31-100% battery charge. When red for five seconds, 15-30% battery remains. Finally, if the indicator is blinking red, you have less than 15% battery left. Hold for 1.5 seconds: Turns on the headphones. Hold for 3.0 seconds: Headphones off. Volume Button: Increase and decrease the volume. Microphone mute button: Short press: mute and unmute the microphone. Hold for 5.0 seconds: Switches the connection. When the indicator is blue, you are using a non-Bluetooth wireless connection. When the indicator is blue, you are using Bluetooth. Double tap: Activates the microphone's side beep, allowing you to hear feedback with your voice. Single press (while pressing the volume up button): Enhances the sidetone. Single press (while pressing the volume down button): Decreases the side tone. Hold for 3.0 seconds (while holding the volume up button): Sets the volume limiter to 100 dB. Hold for 3.0 seconds (while holding the volume down button): Sets the volume limiter to 85 dB.
