Why are the Koss Porta Pro headphones so quiet when plugged on iPhones?
I have a question about my Koss Porta Pro headphones. Whenever I plug them into my iPhone, they seem to be too quiet. Do you know why this is?
I think I know what you're talking about. The Koss Porta Pro headphones are known for being quieter than other headphones when used with iPhones. This is because iPhones use a different type of audio jack than other devices, and the Koss Porta Pro headphones are not optimized for this type of jack.
