Function. Apple iPhone, iPad line control function (microphone / answer / adjust volume, etc.) can be used.
The Samsung Galaxy and Note series have been tested, the handset microphone and answer button are available, and volume adjustment is not supported.
Other models of mobile phones can only listen to songs and cannot use the remote control function.
Note: Listening to songs is no problem, if it is to adjust the volume, it is only effective for Apple phones.
The cost-effectiveness and creative craftsmanship of this earphone are absolutely excellent value for money.
It is definitely not comparable to low-end goods, but the price difference with Apple's original headphones is too big. If you are picky about the sound quality and pursue the genuine Apple quality, please take it carefully.
