So got the crystals today, the fit on these tips are much tighter than the JVC spiral dots, so I ended up pulling out the nozzle cap again on the right side... Wasn't happy about that... tried to reglue that part but the superglue was dried and I tried to use a needle to unclog it and ended up stabbing the needle almost completely through my index finger when it broke in half... anyways, back to the review XD.
I compared the tips to my JVC spiral dots, in terms of comfort I'd say the JVC spiral dots are superior, the Crystals are kind of grippy... while the JVC spiral dots are quite smooth while not losing on the seal department either, if anything I think the JVC has better seal overall.
Now to the sounds... Bass-wise I think the two are almost equal, JVC is a bit more "bouncy" in its bass vs the Crystals, but it's just by a small fraction. Vocals I think the JVC is actually a bit more forward than the Crystals, however the JVC does introduce a bit more shout on sibilant songs vs the Crystals if we're to compare the two. Highs the Crystals I think takes out the sibilance a little, the JVC gives more of a raw/unedited feeling and as a result is bit more sibilant. This isn't an issue on songs not compressed to hell, but you will definitely feel the extra bit more sibilance when you listening to highly compressed songs. I can't really decide which one I like better right now tbh, I still like the JVC's overall comfort of wear and transparency in sound, but I do like the Crystal's less sibilant sound as well. They're not that much different tbh, I'll give the Crystals a bit more time to see if I can deal with the grippiness and if I will miss the slight bit more vocal forwardness from the JVC.
***Edit
Ok, after listening to less sibilant songs, I feel the JVC's just superior and has less veiled in sound, I personally prefer this less filtered sound overall vs the Crystals, so I guess it's the JVCs for me still. It's less forgiving than the Crystals on highly compressed songs but it's not bad to the point where I can't listen to it. So I guess the Crystals are going back to Amazon... or actually I'll just keep it, don't feel right returning something I've already worn.
