I find that talking about the best tips without mentioning which IEM they were tested with is a bit pointless, as the whole idea of rolling tips is finding good synergy.
The music you listen to, and your preferred tuning, also matter a lot.
I listen to Metal and Rock, and like V-shapes because I love bass and treble. However, I also value mids, so I want the IEMs to shine.
With my Monarch MK3, I liked the tips in this order:
- Divinus Velvet: BEST: Enhances the bass and the treble, leaves mids untouched. Supreme comfort. This will make some tracks sound too intense at times, but I just lower the volume and enjoy.
- Dunu S&S: EXCELLENT: They are a little less intense than the Divinus (very slightly tamer treble), but otherwise sound great. I liked the fit too. They are slightly sticky but nowhere near as much as Xelastecs, so I find them comfortable. However, I keep going back to the Divinus.
- Azla Xelastec: GOOD: I found the sound to be really nice, very similar to the S&S but the material is too sticky for my liking. I can't daily drive these.
- Azla Sednaear Regular: OK: Nice material, nice fit, but the sound is very "meh" compared to the Divinus.
- Azla Sednaear Light: OK: Slightly softer than the regulars, but honestly, I can't tell if they sound any different to the regulars at all. Very meh.
- Tangzu Sancai Wide Bore: OK: They feel cheap on your hands, but are actually very comfortable to wear. However, they killed the bass feel of the mk3s. I will keep them to try with other IEMs.
With my MEST MK2:
I am still trying to find the right tip. I'm not satisfied yet: Wanna check if a short tip (tws?) increases bone conduction and/or tames treble slightly.
- Divinus Velvet EXCELLENT: Same reasons as on the Monarch MK3.
- Azla Xelastec: GOOD: The MEST MK2 actually ships with these. They sound great. I'm not a fan of the material, though.
- Azla Sednaear Regular: OK: Same reasons as on the Monarch MK3.
- Azla Sednaear Light: OK: Same reasons as on the Monarch MK3.
- Tangzu Sancai Wide Bore: BAD. With this IEM they don't work, imho. Too bright! My ears! The IEMs also keep falling off my ears.
- Dunu S&S: TERRIBLE: Wanna kill all the bone conduction and the bass magic? Use these. I'm amazed how good they are with the monarch and how bad they are with the MEST. I've just retried them: It's mostly a fit thing, but nothing I do works. They just won't seal. If you absolutely cram them in to the point where they are super uncomfortable, the pressure builds up and they are damn horrible - sound only gets as good as with the Xelastecs at most, so it's not worth the effort.
For the MEST I have Final Type E on the way, and I'm considering trying ePro TWS (something that gets the body of the IEM closer to my ear).
To complete my rolling experience I'm considering trying AEX70, Nostalgia XWB and Eletech Baroque and Spinfit W1/Omni, but I'm going to enjoy what I have for a while.
Last piece of advice: I thought I had to use size "M" to get a good fit, but with these IEMs with wide nozzles, I have found that I like smaller tips. The Medium hurts after 30 mins or so. Now that I've found that I really like the Divinus, I have ordered another pack that is "MS" (the S will be too small to seal).
