This iem's are kind of pricey and the presentation is horrible. The cable sucks and the shells didn't exactly fit very well my ears. At least the most important aspect that is the sound of course... they sound great. The bass is there, pretty heavy and defined. The iem is a 4/5! The bad presentation and the terrible accessories that comes with the iem leave you expecting way more for the price range.
Loved the sound signature so much I upgraded to the Grand Maestro within a week of listening. FatFreq really has impressed me.
