Echobox Finder X1
Impressions after some playing around (minimal burn-in, in case anyone cares):
First off all. To whoever designed the section that holds the extra filters, you f*ing sadist. That was one of the single most frustrating unboxing experiences of my life. It's impossible to get them out without ruining the packaging. I felt like looney tunes character struggling with the damn thing.
Aaaanywho,
Steps to enjoyment:
1. Take off stock tips and pre-installed white filters and throw them both as far as you can.
2. Install black filters after the struggle (which is real), put on the included small dual flanges.
3. Throw box with everything else you won't need at annoying coworker and run away giggling.
4. Profit.
95% serious...
Filters: Per my ears and the manual:
White: bass explosion (roll off after 200Hz - joking... kinda)
Black: balanced (less bass, not sure about treble)
Red: treble enhanced (lowest bass, most treble)
That's the combination (black filters and included dual flanges) that yields the best balance of timbre, linearity, note weight, clarity, and soundstage.
Everything else massively skews the response to looney toons proportions. (To be fair, if you want to pull the bass down a bit at the expense of slightly rougher and brighter treble, the red filters are alright.) use the comply for something else.
These are massively sensitive to seal and tip rolling.
Long tips like the included comply and MH1 tips muddy up the midrange and treble to a staggering degree. Wider tips like the stock red stems super amplify the treble peaks.
With my settled combination:
Bass hits very hard, and it's very tight. Clearly above neutral but mostly peaks at around 40Hz so it stays pretty clear of the midrange. Probably a bit less in amplitude than it feels but it has the illusion of significant quantity because it's powerful and tight.
Really, the whole sound is pretty engaging.
Midrange is really detailed and really clean. Very solid combo with the solid imaging.
Treble is just on the edge of sibilant for me but keeps it together better than most that are on the edge and is totally listenable.
Stage is crystalline, clear and airy and really drive home the tight and detailed sound. Could be bigger but the right tip/filter combo and it's really very adequate with great layering which makes up for it.
Imaging is really good.
Very solid performer and very good at the indiegogo price.
Really, wrong filter/tip combo, and these sound pretty bad. Enough for me to say that the difference is almost unbelievable. I suspect from this that they would EQ really well.
Was gonna give them away for Christmas to family, but since I mauled the inner box and got them to show their good side, I think I'll be keeping them.
