Query: LG Handsfree Stereo Headset

I needed a new headset when I upgraded phones to the LG Rumor Touch. My old phone had a 2.5mm jack and the new Rumor touch has a 3.5mm jack. I could have gotten an adapter but that was basically the same price as many new headsets. I chose this product because the description specifically said "For use on either 2.5mm or 3.5mm headset jacks". Based on that product description, I concluded that an adapter came with the product...I was wrong. Now I have a new headset with the same 2.5mm plug that I already had with my old unit. The product works fine with other phones with the smaller jack, but I still can't use it with the Rumor Touch.
