And compared to the ones posted by vegetaleb 2 pages back, they look as wide for less bass but you said it has a better seal, you mean a seal on the iem or in the ear canals?
Yeah, I saw vegetaleb's photo, but I don't think he said where they came from.
As far as my 'better seal' comment, I meant ear canal. The KZ Turbos have the same size bottom part as the Starlines (ie the part that fits onto the IEM nozzle). It seems to be the most common size out there (pretty sure it's 5mm).
