We live in a society that loves to customize it’s cell phones and cars. Well the folks at Horntones have ingeniously taken that notion a step further: in April look for the Horntones FX-550, a clever $150 USD device that lets you to customize the sound of your horn using almost any standard audio file. The dashboard-mounted device stores hundreds of different sounds; some are pre-loaded, and more can be downloaded from Horntones.com. Here’s the fun but scary part: you can create your own tones in MP3 or WAV format. Yes, you can have any sound or song clip as your horn, whether it’s naughty, nice or just flat-out obnoxious. A USB thumb drive transfers the sounds from your computer to the player, which never has to leave your car. You can even create your own themes, utilizing the 8 preset buttons on the player. Could be fun, or a complete nightmare on the roads if this actually catches on.
