Title: Phillips Fidelio S2
Post by: Marvey on June 23, 2013, 06:14:14 PM

Not much time since I'm busy on other things, but really quick impressions based on a few seconds on three recordings I know well.

• They sound pretty good
• Slightly bassy / warm - toward upper bass / lower low mids
• Good bass punch. Maybe a little bit one-note-ish
• Slight bump around 4k
• Not laid back in the treble - this is good
• This results in maybe a slight recess in the vocal fundamentals region (in audio engineer parlance, not science speak.)
• No, they are not TOTL quality in terms of clarity or detail, but...
• No issues with seal / cheapy plugs worked for me
• I would easily recommend them (assuming $200? I dunno)

Quick measurements coming up in a bit...

These sound warm & bassy despite this FR?!
I predict strong distortion in bass. (and in 30s the THD will be posted, heh)

Distortion - calibrated to 90db SPL/A white noise. Left.

Interesting, I've expected closer to 1% - but perhaps this might be due to relatively high amounts of high order distortion in bass. Even D5 is near 0.1%, higher orders might be too.

Is it possible to have your rig measure frequency-dependent IMD too? Say, an IMD sweep...

actually only $149. warm with that FR may not be a bad thing... seems interesting. would love to hear.

Guys, don't confuse this measured bass response w/ an ER4S, it's not a warm version of an Ety.  It has more bottom end than the Sony EX series.

This is one of those IEMs where it measures really great in basically every parameter, but the sound is mostly meh, not really mindblowing. It's a nice, do no wrong IEM, but it won't give people goosebumps. It's warm and fluffy. In that respect, I was slightly disappointed. I'd get it during Black Friday, but not any other time.

Agreed - nothing special - but that it does nothing seriously wrong - and that last aspect never disappoints me.
