When I plug my speakers into a headphone jack on my iPhone, is the output stereo or mono?
1 Answer
The iPhone headphone jacks are 1/8" (3.5mm) stereo jacks. If you have a stereo cable plugged in, the output will be stereo.

Interesting side-note, the external speakers on the iPhone are 'mono', and I believe only output the left channel..– notthetupApr 23, 2011 at 17:49

1@ntt On my iPhone, of the two holes on the bottom, the one on the right (if the screen is facing you) is a mono speaker and the one on the left is phone's primary microphone.– KalamaneAug 26, 2011 at 16:10

Indeed.. But it takes the left channel of the audio to send to that mono speaker..– notthetupAug 30, 2011 at 7:49
