Just got this guy in, a Sony WM-EX909 with dual heads, yep dual heads, it not a recorder, it use a head for each side two physically separate heads, never seen a unit like this before, Sony only made four models like this. tranports look weird. Sound is fantastic on this unit, came out in 1992.

The 909 was one crazy Walkman. It wasn't shy about advertising its dual-head design.
