I bought this product for my RAZR V3x. It works ok for headphones to hear my music. I'm not real picky about the quality of the sound. These headphones do not produce a exceptionally crisp, clean sound. You can hear your music, and that's pretty much what I expected for the price. I also could not get them to work as a headset with my phone for sending or answering calls. The people I talked to couldn't hear me; said it sounded like there was too much static or interference. So it's an instance of you get what you pay for.
