I am waiting for LZ A7 replacement (defective connector on 1st unit, ugh!) Curious with these tips what filter / switch setting you like on A7, and how they affect the fit / seal with this particular IEM. Your additional impressions will be much appreciated, @IEMusic! Thanks, and enjoy.
What I like about the elliptical tips with the A7 is that they allow for a deep insertion/fit, with a great seal, and no driver flex for me. Sound wise, they are quite transparent IMO. The bass and treble are more focused, but the overall tonal balance is not altered much it seems.
