They are the same. We are buying them for our other earphones. They seem to optimize sound for a lot of other earphones and not just the FX850..Considering the FX850 only came with one pair of each tip size. Them boxes of tips are 3 pair of whatever size you use, so far they make my H3 and IM03 sound their absolute best so worth it for me.
It was an unexpected discovery to be honest. I like trying out other tips with my phones to see which tips sound the best with the phones..I was very surprised how the sound opens up using the FX850 tips. The extra wide bore on the nozzle seems to help out with sound channeling to your ears.. Don't know how much of that has to do with them spiral dots but the end results kind of speak for themselves.. Standard tips Sony and Audio Technica uses all seem to be the same variants.
It is refreshing to see that JVC took the time to actually develop a much better silicone tip vs your standard..I wish all earphone manufacturers would give some thought to how a great tip can actually help the sound they want to achieve vs just throwing in their house made tips.. SONY is the most guilty.. They make large Hybrids and multi driver BA phones yet just throw in their standard hybrid tips that actually constrict the sound. Throw on something like a UE tips or better these Spiral dot tips and you get a wide open more fluid sound.. Likewise with AT.
