I also am liking but not sure I will keep these. I have compared these as having a sonic signature like the SRH-1840 which I still maintain but I actually want more forward mids like the SRH-1440. These are either to neutral or possibly are ever so slightly u shaped. There is nothing wrong with this MANY will love it, but it may not fully suite my tastes. I will probably give these a or 2 full days of burn in before deciding though.
I also find the detail of these to be less than what I like but I am also used to multi hundred dollar full size and IEM products, so my observations are not really fair. At it's price point this IEM competes with most $200 IEM's so is a good value. It just doesn't compete with the best $200 IEM's because they elevate their game to the $3-400 level.
For me these are still the nicest JVC I have heard to date.
