As part of its new range of USB audio products, Aiwa has come up with a digital audio player that uses a USB flash memory key in place of a conventional memory card. The company’s own Pavit memory keys and Sony’s GigaPocket/MicroVault memory cards are compatible with the players, of which Aiwa plans to put several models on the market in February and March in major international markets. Because they are memory key devices users only need to insert them into the USB socket of a PC to transfer songs. The AZ-ES256 is the basic model and will cost $US215. The AZ-RS256 adds a radio and digital display for $US245. Versions of the two players, which are round medallion devices, are also available mounted in headphones for the same prices.
