B9Scrambler has a review over on Head-Fi of the BS1 ear bud. For $39 over on Ebay I doubt you could go wrong. Click on the review link below to see photos and the B9Scrabler’s review.
Pros – THAT CABLE!! YES!! – Comfortable, light design – Well-tuned mid-focused signature
Cons – Bass extension – Average sound stage for an ear bud – Poor L/R indication
