“My first in-ear headphone. Always thought they couldn't be any good compared to the over-ear headphones. I was wrong. The looks are a matter of taste, so I keep that in the middle for a review. This Philips Fidelio S2 starts with a superb build quality. Distinctive flat cable is a bit short. Works fine with a device (phone, mobile player, etc) in your pocket when on...” --Antilochos
“ This IEM is definitely the best bang for the buck! Basshead person should purchase it without a doubt. Even it's higher brother, Philips SHE9800 didn't able to match the sound quality of this IEM! :D It produced very deep punching bass and high definition clarity on mid and treble. It feels like you have your own built in sub-woofer inside this IEM! Comfort to use in a long run,...” --chrone

“thanks to it's overall sound quality, details are not even a problem with kdx200. you'll get back every detail you lost on cheaper models like Xiaomi Piston, Brainwavz M4-M5. and there's also some things you'll gain if you're coming from vsonic models. kdx200 is one of the earphones that finally worths it's price and does not absolutely lacks anything. it's highs are not good enough...” --vaziyetu
“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)....” --Tetsuro P12
“ get one if you can , come with a small plastic carry case too and about SQ its a 3580 with a bit more forward mids and smaller bass . bass is as deep as 3580 , nice detail , good mids , vocals are not most enjoyable but what can you ask for this price ? instruments are there thankfully if not clearly separable its good enough , sound stage is okay , nice highs though , a bit grainy but...” --suman134
“Accessories: Three sizes of single-flange silicone eartips. Build Quality/Design: This is probably the only part of these IEMs that feels like it belongs at the price point. The housings are entirely plastic and don't feel extremely durable but not extremely fragile either. Little driver flex is present. The cable is very poorly relieved, with no strain relief at the housing end and stiff...” --gopats1479
“Bass junkies will love these as it is probably the most prominent iems out there when it comes to bass. But after 120Hz you are into the bog of mids and garbled highs. RUK30 fail to deliver the details of you classical, folk, new age, fantasy pieces even when specifically amped and equalized for the details you hear from your over-ears, you will not be hearing them. ” --Teleman
