Clarity is unreal however. Surpasses RE-400 clarity, but RE-400 mids I think might be slightly better, IMO.
The shell is much smaller than pics make it out to be, and a lot less ugly in person. I kinda like it.
If the 4k peak dips a bit over time, I'll have a new favorite. Definitely a winner at $60.
As I mentioned, the 3-4k bump is classic Audio-Technica, and is pretty much commonplace in Japanese-style IEMs. I don't think it'll go away, but perhaps you'll get used to the signature.
But yes, the RE-400 is still a superior earphone. It has superior bass control and articulation, more transparency across the board too. The sound signature is more laid-back and may contribute to the difference in clarity. However, for $60, I still think the SS01 is excellent overall.
Maybe try EQ-ing down the mid-bass --- I think the sub-bass ability is fine (bumping up the sub-bass increases chance of distortion); it's just that the mid-bass is a bit larger in amplitude.
The white version is probably the best looking version. The red version I had was just not very good looking, to me, at least.
Anyway, these aren't with me anymore. jgray91 should be receiving them any day now. He'll be doing a comparison of it against the HA-FXT90.
