MP3 Sunglasses With Voice Recorder

RFQ Details

We are starting a mail order business and would like to sell MP3 sunglasses. To begin with we would like two or three models with different prices and functions.
Product marketing will be through a website and print media.
Our main requirements are to have an mp3 player with a good voice recorder but would prefer if available all these features on one player.
MP3 sunglasses with Voice Recorder, Bluetooth and FM radio.
A unit that will clip on to existing sunglasses/glasses would be better if available.
We are uncertain of quantities as this will be determined once our add goes to print and the orders generated. This could be between 100 and 5000 pairs. We would need supplies quickly so capacity must be able to cope with possible large order. We could of course place a limit of pairs available in our add. We will need the players to be set in English apon arrival with good instructions.
Rechargeable USB or Mains. Battery
Plug and Play.
