I just got a pair of Ikko OH1. These are really good. Definitely the best pair in my collection. Highly resolving for an exciting sound sig. Impactful bass with emphasized vocals yet I don't hear if any congestion. I'm used to hearing congestion with this sound sig. It's very clean and airy sounding too. Very, very impressive for $140. The case is very beautiful. Pictures don't do it justice. It's not that reflective in person. It's a soft reflection. The case is also compact and comfortable. It doesn't stretch any part of my ears. The wire reminds me of KZ ZS10 wires which isn't too bad but it's not as nice as TFZ's. I don't get much sound from wire rub.
