I Am Using An Apple Headset For Phone Calls And I Have Set The Headset Volume To The Maximum. Why Is The Call Volume Still Too Low For Me To Hear - Huawei Honor 7 Faq

3.170 I am using an Apple headset for phone calls and I have
set the headset volume to the maximum. Why is the call
volume still too low for me to hear?
There are two standard headsets with microphones. One is the international CTIA standard
with 3.5 mm headset jacks. The connection method is left audio channel > right audio
channel > ground cable > microphone. This is the most widely used method in the market.
The other is the national OMTP standard with 3.5 mm headset jacks. The connection method
is left audio channel > right audio channel > microphone > ground cable. If a headset of the
international standard is connected to a headset jack of the national standard, only background
noise can be heard. You have to press and hold the call button above the microphone to hear
voice.
Huawei mobile phones adopt the international CTIA standard for the headset jack. Therefore,
if you are using a headset of the national OMTP standard, this problem will occur. The
insulating ring on the headset jack of the international CTIA standard is usually white.

using the built-in video player has only images but no
sound?

support the AC3 format. Now Huawei phones all uses the DTS sound effect.

bottom of your phone and the secondary microphone is near the headset jack on the top of

3.174 Does my phone support macro photos? Does my phone
support autofocus and manual focus for photo and video
taking?
