The tie clip MP3 player is exactly what they say, an MP3 player tie clip. What is a tie clip? What a shame! A tie clip is a simple clasp or clip used to hold the two ends hanging from a rope together. Sometimes it can cut a shirt underneath so your tie will not move. Now, throw in a single line LCD, some simple play / stop, and some flash memory and you have a tie clip MP3 player.
You can even use it as a message board, as a “Hello, my name is…” Or accidentally falling into the Republican convention with “Bush Sucks” flashing for all to see.
