I have both.
The Timeless are outstanding for their price.
Out of the box — I don't care much for burn-in although I agree it can make a small to big difference depending on the driver(s) — the FD7 are equally outstanding.
With the bass nozzle on the FD7, I find them to share many traits with the Timeless despite their different drivers and setup.
The only exception to this is the sub-bass where the Timeless have the edge (or at least more of it).
But that says a lot in favour of the FD7 as I find planars to have the technological upper-hand (generally-speaking).
At their price, the Timeless are a no-brainer but the FD7 are clearly the most flexible of the two.
Both compete
way above their respective price range.
Nota bene: I used both IEMs with Final E tips, balanced, running from a brand new M11 Plus LTD with the Super Slow Roll-off filter (yes it makes a difference and those of you who sold your M11 Plus LTD without trying the filters: you should have
).
