The JHA are brighter more forward pieces. If you think the Shure are forward, which they aren't, you should look at Westone instead. They are more mid recessed than either and to you will sound more pushed back. To me they sound overly distant, Shure closer, Etymotic spot on.
As for clarity, look to your source or amp. The 846 is right there with the LCD-3 I just sold in favour of only using the 846.
