Nice take and I agree. As a person that only owns two IEMs--The Timeless and Fiio F9 Pro I can't really speak with any authority as I'm way more an over-ear guy. With Timeless my experience has been generally positive but I have found that the larger stock tips--the dark blue with yellow--work best for me as my main complaint was lack of sound stage coherency, which these tips fixed pretty much--I.e. the seal was better. Also, these can be sibilant and that can get wearing on certain music. Mine are not much burned in--maybe 6-7 hours total play-- so that may be a factor. Also I find with higher current amps--my Schiit Magni2 Uber being the best example of stuff I own---gives the best sound return and from reading multiple reviews, like all planars, the sound improves markedly with higher current. My Shanling DAP w/760mW does OK but not ideal.
