If anyone is considering these I might also suggest spending 12 extra dollars and just buying the one more triple driver in ear monitors that woot is selling right now for 30. (Plus 10% off or $27 if you get it today although that applies to every product on the app).
It comes with three pairs of foam ear tips, plus another five pairs of silicone, plus a leather case, and a bunch of other adapters. Even without the in-ear monitors you’re probably getting $30 worth of accessories and the foam tips you need here. (Although I suppose there’s no guarantee the one more dual driver tips will fit whatever specific solution you’re looking for).
So why not get a pretty good pair of triple driver in ear monitors while you’re in the process?
