iMore

Hi after whole 6 years of using BB, I finally got an iPhone 6S and switched to iOS and im so happy with that. But I had this problem when I first put my headset to the phone and opened some musics, I saw that the sound of the original earpieces are not as I expected, and I compared it with one of my friend's old iPhone 4. The iPhone 4 was rocking the 6S at headset. Sometimes when I listen music outdoor, the volume is not that much high and I can hear the environmental sounds. I checked some solutions from the net which is without jailbreak, but It was a bit old So I hesitated. I wanna ask If we have a new way to multiply headset volume and be happy ?

Thanks.

I did it on an iPhone 4 by using iBackupBoot by having a full backup of the device and editing com.apple.celestial file by changing the multiplier coefficent of the volume but in iOS 9.2.1 it doesnt work. I will post the pictures.
