Just think how much more pleasant NYC would sound if those annoying cab honks were replaced with MP3s!

The Horntones FX-550 System is said to be the "first mobile audio system that supplements the sound of a vehicle's horn function by sounding any MP3 audio clip." The system consists of the FX-550 music player, the AP-150 audio amplifier and the rugged SR-100 speaker. The player has an MP3 capacity of 256MB and has 9 preset buttons, all of which can be assigned a "theme" to vary what you want your horn to play.

To add songs, go to www.horntones.com to configure your system with the site's "Virtual Player." Then, save those songs onto a USB thumb drive. Plug your thumb drive into the FX-550 player, and you're ready to go! You can even upload your own custom tones.

The Horntones FX-550 System ($250) is now shipping and can be purchased at www.horntones.com.
