Do you generally believe in the burn in thing? It just doesn't sound right that an earphone needs upto 200 hours to evolve it's sound. To me it's a marketing ploy. Regarding how thin it is, I honest still think it's a bit thin on the thin side, but it does not necessarily always mean its a bad thing, as generally thinner midrange produce better clarity and crispness. Hmmmm, the wide tips seem to give me hardly any bass with a more thinner sound.
To be honest, I'm only going on what I've read here and from what Paul from iBasso said regarding burn in. But I don't know if burn in does work or not.

I'm absolutely amazed you're not getting much bass from the wide bore, that really surprises me. I'm getting really deep bass and sub bass and I'm not even using my FiiO amp at the moment, I'm just plugged direct into the laptop. However, wide bore or not, I find larger tips generally give me more bass than medium or small size. I'm also surprised you think the mids are thin. Can I ask, do you have them fitted in your ears correctly? Tonight there was a point where I was thinking, hmm, I was getting much more fullness earlier on. Somehow they weren't oriented correctly in my ears and after adjustment, all the fullness came back.
