What to do, what to do? The Cyclone PR1s with shipping are about $61. The MeElectronics Ai-M6 are about $38 with shipping from Overstock.
Contrary to what you may think the M9s sound different enough from the M6s that several reviewers (e.g. mark2410) couldn't believe that they share drivers. It might be the design of the acoustic chamber in the housing but the M6 sound tauter, smoother, and better balanced overall. The M9s are still an amazing buy at $20, but given the choice I will always spring for the M6.
