Massdrop Blue Box: Brainwavz IEMs

Brainwavz Blue Box

Looking for a pair of high-performance IEMs? We’re partnering with Brainwavz to offer an exclusive selection of goodies, featuring well-reviewed products that pack a heck of a punch for the price. And because it’s not a Blue Box without some extra excitement, we’ve included special prizes, too. If the quantities are unlocked, two lucky members will receive Brainwavz's new B400: its flagship quad-driver IEM.

Note: This drop is limited to a maximum of 640 units (limit 4 per member). Shipping is free for US members, regardless of whether you purchase 1 or 4 units. For every purchase in this drop, you will receive a randomized product with the odds listed below.

What Are the Odds?

Every individual purchase in the drop will receive one Brainwavz unit from the list below. The prize drawings will be selected immediately so that everyone has a fair shot. Participants in the drop will have their order number swirled around in a random number generator that allocates IEMs accordingly. Below are the odds for each model. Please note percentages are rounded.

  • Brainwavz Jive ($24.99 value): 15.6%
  • Brainwavz S0 ($44.99 value): 46.9%
  • Brainwavz S3 ($74.99 value): 15.6%
  • Brainwavz B150 ($69.50 value): 6.3%
  • Brainwavz M100 ($89.50 value): 15.6%

Sweetening the Pot

Community participation is the name of the game, and we’ll be adding some neat offerings as the drop gains traction. Every purchase counts as an individual entry for these prizes. There are a total of four possible prizes, and each is unlocked when the respective number of units are purchased. The odds of winning each prize is 1 divided by the number of participants.

  • Unlocked at 200 purchased: Brainwavz B400 IEM ($189.50 value)
