The blow out sale has only been around for 2-3 months, I bought my first pair back in oct 11', so I have no clue which model I have.

You can use the word "defective", but from talking with TRF, they should be a complete unit that works, but was never offically tested out and sent to the "good" bin.

The pair I ordered looked perfect with no defects that I can see, but results can vary.
