The JX family
Aiwa's JX series portable cassette players represents the most advanced and feature packed they've ever made.The top of the line AIWA HS-JX707 was released in 1991. It is essentially the same as the HS-JX70 and the golden version HS-JX3000 released later in Japan. It is packed with the best features available at that time such as Dolby C, Amorphous Head, BBE which enhances the clarity of high frequency sound, DSL, PLSS and even voice navigation! This is one of the best AIWA portable cassette player ever! There was a later model HS-JX929 released after the HS-JX707, but is wasn't a true successor to the JX707, in fact the only change was the new logo due to Aiwa's acquisition by Sony on Feb 28th 2002.
