The Best Car MP3 FM Modulators

By James M. Boersma


When shopping for a car MP3 FM modulator, it's hard to find a truly well made product. Most modulators are made by huge companies that don't feel it's necessary to make quality modulators. They just assume they can put whatever product they want out there and people will still buy it. Once you sift through all of the garbage, it is possible to find a quality wireless FM modulator; you just have to know what to look for.

Let's first examine what a modulator does:

Wireless car MP3 FM modulators allow people to broadcast audio, usually from an MP3 player, to their car's antenna. The antenna picks up the signal and plays your audio over an unused FM station. Modulators are especially useful in older vehicles that do not come with an auxiliary jack. When shopping for a modulator, there are many important differences to consider when deciding which unit to purchase.

The following are reasons why a low quality modulator has such poor performance:

1. Low Cost: If you paid less than $30 dollars for it, chances are the quality will not be very good.

2. Only a few frequencies to transmit on: If these frequencies are being used by commercial stations then your audio will have lots of interference.

3. Poor audio quality: Cheap modulators usually can only transmit a few feet, which is why their performance is so poor. That type of transmission creates such an inferior sound, it will be near impossible to enjoy your music.

4. Only usable in one automobile: Whereas high quality versions can be used to broadcast in multiple cars.

5. Compatibility issues: Most low grade modulators are compatible with only one audio source, be it 3.5 mm or iPod. If you have both, or like to switch back and forth, you may not be able to do so.

A high quality wireless car MP3 FM modulator consists of:

1. Ability to broadcast over the entire FM Band (88.1 to 107.9).

2. Preset frequencies and microphone compatibility give a quality FM modulator even more versatility.

3. Large transmission distance and power (up to 150 ft, near the maximum under FCC regulations).

4. Quality modulators are compatible with almost any audio source. Because they are so versatile, they can be used in virtually any location you can think of.

5. Tons of ways to power the unit (wall adapter, USB, batteries and cigarette lighter) so you will never lose power.

Everyone wants to play their personal MP3 players or iPods in their automobile, and they should be able to do so. But, they should also be wary of cheap FM modulators, which will severely cripple their audio quality. However, by spending a little extra for a high quality wireless FM modulator, a consumer can enjoy their music through a variety of options.
