It's not V shaped at all~ and it's no where close to V shaped, especially the new FP model. JH13 FP is not mid recessed and the overall presentation is actually a little bit forward, the vocals are placed quite well. If you like "smooth" vocal, I would actually suggest it.
Although it's very detailed, JH13 has a special sound tuning, it's combination of upper mid and lower/mid treble doesn't provide the best transparency and the most accurate imaging. If you like it, you might think it's one of the best, if you don't, you might find the bass is a bit strange and the presentation isn't neutral enough.
Hmm, that sounds quite good actually. I was just worried about it because I previously have owned the TF10, which I'd assume the JH13 was just an improvement of that type of sound. I'm guessing that's wrong?
