Customer Review: works, but it will break
I have had a common experience a lot of Samsung SGH105 users; I want to use a 2.5mm headset with the proprietary Samsung jack. I bought the Belkin adapter, it works fine for a month or two, until it breaks. I have now gone through two of these. It breaks because it is made poorly. If you never put it in a backpack or in your pocket, you might be OK for awhile, but it really shouldn't require such delicate care. Set your expectations up front and expect that this will work for a few months and then you will have to replace it.
Customer Review: Adapter hardly worth it
I was disappointed when I finally received a product that would allow me to use earpieces not designed for the Samsung SGH-s105 phone. When it is plugged in, interference can be heard from both parties. However, it is even louder on the recieving end of the phone call than from the person making the call. The only saving grace of this product is it's price and that's not saying much since I had to buy 2 in order to justify the shipping costs.
