Pros: -detailed, dynamic, neutral, relaxed sound
Cons: -rolled off highs, too sensitive (requires quality source), problematic cable
I use these IEM's at work and during travel, it's very easy to transport with the small metal case. It was difficult to achieve the good isolation, i tried 10+ pair of silicon cushions and i finally got one which fits perfectly into my ears. These are very sensitive IEM's, if you hate source noises stay away from them, i hear little hiss even with my desktop amp/dac combo Corda Aria, probably they need an expensive portable player, but i use simply with my phone and notebook. (Maybe i have to build a resistor attenuator)
The sound signature is pretty balanced, it has a solid, tight and well extended low end (only with perfect isolation), for me it's just the right bass. The mid's are well pronunced, detailed, but never came too forward, another point were these shine. The problematic side of the sound is the high's, were these simply don't have enough extension. The resolution and accuracy is there but it has a significant roll-off here. I recomend these for classical/jazz music.
