Agreed! The best IEMs i've ever owned. Earlier had used the legendary Sony MDR XB09EX which i had gifted to my gf, those had the most earth shattering bass but overall kinda muddled other frequencies. Then one of the earphones stopped working so bought the Sennheiser CX 3.00. They were good but i was missing that powerful bass so got the Sennheiser Momentum M2 IEMs which had great bass but then i gave them to my gf once i got the RHA MA750. Quite happy with them now. Initially they sounded very flat with hardly any bass. But once the burn-in was done and i got the right eartips, they sound almost perfect now. Better soundstage and tighter bass compared to the previous ones.
