I already liked the SE5U a lot when I had it (even twice) on a loan over here for some weeks, years ago...
As you can see in that pic I cut the hearts out of some silicone black tips and put them around the nozzles to get a good seal and comfortable fit. But that worked totally fine for me at the time
When both Nebulas are even an upgrade (in sound) over the SE5U, then I bet that they must sound fantastic indeed!
I'm also not a specialist in taxes. But I interpreted that VAT was meant as import taxes here and I've never paid (extra) import taxes for anything that I ordered/bought within the EU (incl. Poland). On the other side, I had to deal often with import taxes afterwards when I ordered/bought something from outside the EU.
Now, if this part is correct, then I can understand that Spiral Ear charges that extra 23% to their local and EU customers. But at the same time it seems that other Polish IEM companies like Custom Art or Lime Ears don't do it that way. They show exactly the same product prices for all of their customers on their websites, no matter where they're located. So, because of that, this different approach of Spiral Ear just came across as a bit strange to me initially![]()
Nice to know you could make DIY universals out of it and points for ingenuity


No idea here and I've never had a chance to listen to their previous CIEMs.
Points taken. Perhaps a differently established legal company structure can allow that? Don't really know.
I may have a possibility to audition CFA Clara in the next few weeks and I'll be taking DX 260 with me. I'm really content with my current setup, but just for kicks and getting more experience. What source could you recommend for best synergy?
