Audio Splitter Jack 3.5mm to dual female U Shape 2 in 1 (Mic & Audio) - black

Audio Splitter functions to unite the plugs on the headphones which usually have 2 (mic & audio) into 1 plug (3.5mm Male Jack) so that they can be used for cellphones (mic and audio functions work).
 
Can be used to add an external microphone (to get a clearer sound than the mic from the headset), so that the headset and mic functions work on cellphones.
 
It can also be used for laptops that only have 1 plug so they are limited in choosing headphones that are usually available in the market with 2 plugs.
