Does the BH-111 have a 4 pole 3.5mm jack? I'm wondering basically if I plug my own headset in will the Mic and inline controls from the other headset work with this device? Or is this just for headphones?
You can connect most headphones and earphones with 3.5mm connector but I'm afraid most headsets with inline controls won't completely work. The built-in operating keys of the device serves for that purpose.
