I think that this is the first time I use it, but there are times when it is difficult to listen a little because the low voice of the opponent is emphasized. (It overlaps with the sound of the car while driving a truck) I do not listen to music, so I want you to be able to listen only the voice frequency band. I believe it is the same idea as a communication device (transceiver). The sound heard by the other person seems to sound like a little cold with a sound that is scary. It is said that it is not the voice he is listening all the time. The power switch and the LED display are the same button, when you push the button you can not see the LED and you need to press it for about 7 seconds it will not turn on the power so it is always pushing at the tip of the nail (slightly inconvenient) , Depending on the phone, but my phone can not be used unless it is re-registered every time I use it. (It is registering again every time of charging.) When considering in total, I think that it is suitable for the price ....
