SomePersianGuyYes...you buy in at $25 with a 65% chance to win the baseline M-Duo IEM units. There is a 31% chance you will get a MEE a151 IEM unit (which is actually going for less than the M-Duo's). A 3.25% chance you will get the Wireless Stereo headphones.
And then there is the most remote of remote chances (0.00125%) that you might get one of five "bonus" prizes that Mass Drop is throwing in if a certain amount of people buy into the drop.
So, you basically have a 96.75% chance to get a $40 set of IEM's for $25 bucks (+ $3 shipping).
Good luck to you and my the Audio Gods be in your favor.
