I have been blown away by the Yamaha EPH-100, the first earphones that I can use across all the genres I listen to. Their clarity is beyond what I have experienced so far with portable audio, even with more expensive IEM's and headphones. However, I still find myself craving the texture, warmth and depth of the lower frequencies that you get with full size headphones. The problem is this, I haven't been able to find any closed back full size headphones that have that same level of detail as the EPH-100, and in any case, all the headphones I've tried so far have cooked my ears ! literally glowing red !

Maybe Multi-Driver IEM's can reproduce the same clarity with the addition of the lower frequencies too? So, to all the EPH-100 owners out there, do you also own IEM's (customs or not), that have both the clarity and detail of the EPH-100, along with the texture, warmth and depth of full sized headphones? Could you post your recommendations here?, thanks in advance. I am very interested in any comparisons between the EPH-100 and the ACS Dual Driver or Triple Driver, but I am open to any suggestions whatsoever, headphones or IEM's...

















the bass is just perfect, I couldn't be happier.
