    Works great with Samsung Convoy 2

    Posted by Jim L. on 7th Feb 2017

    I bought the 01-PC35-PH25 adapter cable because I needed to use a full (over the ear) headset with boom mic with my Samsung Convoy 2 (SCH U660) cell phone. It converted the 2.5mm TRS connector on my phone to separate 3.5mm headphone and mic plugs which I plugged my headset into. Works great. Now able to talk hands-free in super noisy locations. Great customer service as well! Thanks!

    Great product. I have been using one for a couple of years and this purchase is just as a spare.

    Worked as I had hoped!!!

    Worked great on an older Panasonic portable phone model: KX-TGA542M, adapter cord is larger/stronger than the headset cord.
