The Philips Fidelio S1 are undoubtedly high quality IEMs

Posted

Pros: 'Flat EQ', wide soundstage, good isolation, good build quality, hard case, microphone included

Cons: Unforgiving on badly mastered tracks, a bit hard to drive (need good amplification), not really the bassiest set, no volume slider

As for any 'flat EQ' speakers these IEMs lacks a bit of energy and sparkle (not definition, they have plenty of it!), not everything is rendered precisely since they try to do everything (in particular I do not like the rendition of cymbals), so they do not excel in any particular area except for soundstage (I noticed that it's a common problem with IEMs that try to expand the soundstage). Every instrument have it's proper position in the scene, that's a big plus. The bass doesn't mitigate mid frequencies, everything is kept at bay but voices aren't rendered forward so they are not really prominent. They are clearly unforgiving on badly mastered tracks so a few could sound a little...

A good headphones after all, just don't expect what a portable headphones can't do.

Pros: Warm sound, decent soundstage for a closed design, good bass, long and thick cable, very good sound isolation, very comfortable, nice solid case.

Cons: Treble rolled off, mids recessed, veiled sound if not properly driven, sound leak, need proper positioning on ears, no remote control, fixed cable.

Warm but dark and a bit veiled sound. On the quiet side (a bit quieter than AKG 430). 2K and 4K frequencies are a bit sacrificed so voices are a bit muted and shady. Mine suggestion is to boost the 1K band with +1 dB, 2K with +2 dB, 4K with +2 dB and the 8K band with +1 dB. Can be driven loud (given a proper amplification) since it has a very low distortion.   I needed to amplify mine collection to 100 dB with MP3Gain to have a decent sound pressure with the current smartphone. I think they lose roughly 3 dB to the AKG 430.   At start I was very disappointed but comparing them with an old pair of AKG 430 I didn't find them worse, just different. The AKG are brighter and more...
