So I read this entire thread and I ran into a few posts about JVC Spiral Dot tips not fitting the nozzle on the A5s correct. Or coming out of the nozzle when worn in the ear. I am gonna post a mod that might help guys explore much wider tips to experiment on the A5. Take a look at this pic. The shape of these EDC phones are similar to the LZ A5 here I figure I would give this example. In fact what I have on here are Spiral Dots. So What I do is I take the smallest tips size the earphones come with. Throw the tips on the nozzle shaft of the phone backwards. Or top of the tip onto the nozzle first. If you see the top phone you can see what I did there. This increases the thickness of the nozzle quite a bit. I flip the rest of the tip onto the shell like the one on the bottom. Then you can throw on your Spiral dots/ whirlwind tips.This lets you throw in the widest bored tips you own. Spiral dots bore here are roughly 5mm wide and this will balance out bass to treble for a lot of people. Give this little mod a try. This might not work for everyone but it might work for you especially if you use medium to large tips sizes.
