The sound quality of this device is absolutely horrible. It does work, and you get something through your radio that you can make out as music. Even a tape adapter is MUCH higher quality thatn this thing. If you're even remotely serious about music, forget it.

Now that I see it in person, the USB design is pretty dumb. So, don't consider it a selling point.

At first this sounded like a cool idea. Take the MP3 player from the gym to the car and get your music. No CD's to burn. If there's a quality unit that accomplishes the concept then I would own it. This is not the one.

I tried 5 of these (yes really....I'm a slow learner). One worked, well sort of. The issue appears to be in the plug. If the plug connection from the unit to my MP3 player is just right then we have stereo. If not then we have an "underwater" sound music coming from the radio. The other units were all "underwater."

As for the one unit that worked, the quality of the sound is just ok. I'm used to CD's in a good player, or MP3 through headphones. But I'm willing to accept FM quality were it not for the fact that the thing just doesn't work!

I'll stick to making CD's, until something of quality comes along.

I purchased one in Dec 2003. When it was used in the car, it never produce quality sound with all the channel selection. It always has noise in the background which can not be removed. The channel selection is very unconvenience, you would need to keep the channel list, and adjust on and off accordingly every time you want to change the FM channel to get better sound.

I was first attracted by its USB appreance. Do not buy!

This is the second try to attach a wireless transmitter to my mp3 player. The SIIG modulator has a nice concept with double use in the car with a cigarette power adapter, or in the home attached to a computer with USB; no batteries are required. Istallation is easy, less than one minute. You need good eyes or a magnifier to set the modulator's frequecy using the onboard microswitches. The sound quality is poor. There is a constant background noise that can't be eliminated (static). The FM modulator cannot handle the full audio spectrum, the frequencies are truncated and the result is a flat sound, rich in static. I tried different combinations of the mp3 player volume and equalizer settings to improve the S/N (signal to noise) ratio on reception. If the mp3 volume is high, the result is a disturbing over-modulation noise in the low frequencies (like speakers with broken membrane); if the player's volume is low the S/N is degrading again, the sound is replaced by static.
If you accept 50% of the quality of a regular FM radio station and a song to song adjustment of the mp3 player's volume for the best S/N zone, this product is for you.
I returned this modulator just like the previous one, in the same day and I promised once again do not touch FM transmitters for another year.

Have tried using MP3 player and Sirius Satellite Radio. Key is to use the best open FM frequency and maximize the output settings on the input device - seems to work just fine then. Had the "underwater" affect on the MP3 player until we cranked up the volume - then all was well. Not bad for under $30.
