FAQ
The sound in my headphones is not correct when I use it in a normal stereo headphone output, or use an adapter plug from 3,5 mm to 6.3 mm jack. I have headphones with remote control and microphone for iPhone on the cable.
Please note that all headphones with 4-pole jack may produce sound that is in mono, is out of phase or is otherwise distorted, if they are connected to ordinary stereo headphone outputs. 4-pole jack headphones are made to control iPhones or other smartphones, to permit phone conversations through the microphone as well as remote controlling of the telephone with the remote buttons, all built into the cable. You usually have to purchase an adapter cable to use them with other stereo sources. This adapter converts the 4-pole male 3.5 mm jack into a 3-pole male 3,5mm jack.
The remote control on my headphone cord does not work with my smartphone.
This problem is sometimes caused by lint and dust collecting in the headphone socket on the smartphone. Please check, and if dust and lint is collected in the hole, carefully remove it with a toothpick or needle. If this does not help, a defect may exist. Also be aware that remote control and microphone made for Apple products do not function with Android products.
