We need to talk about these...
I'm so glad I wasn't able to sell my pair even at a rock bottom price. Curiosity strikes as it always will with unsold items in a drawer.
I remembered originally finding mids a little recessed/muddy/underwater... and I haven't been able to reproduce that whatsoever. If anythign I'm reminded of my Penon Fan for having a hefty bass but also very clear treble.
One potential factor is this time around I'm just popping them in my ears hanging down... I never wear any sets that way, unless it's the only possible way (MX500 shells on earbuds etc) even other earbuds (Penon PAC buds for example) I'll find a way to wear them over ear. No microphonics from the cable, comfortable, good seal. Nice!
Anyway, for the last day and a half I'd been enjoying them a lot. To some extent missing a little but of sub-bass extension relative to mid bass.
Tried tuning foam in my eartips but it just overly warmed / muddied things up.
Then I put stickers on 2 out of 3 of the front vents:
Everything it already had, with sub bass too. Super clean, physical bass, clear highs, mids do not seem unatrually recessed or at a level I would have to volume-creep to keep in the mix.
What a dynamic set!
With the mod, 2 days into doing a lot of listening, I can't really find issue with them. Using the Final E tips pictured.
