Hi Everyone, I need your help in deciding between the ER4S and RE272. I have carefully read every review on the aforementioned IEMs, and still no distinctive answer has arised. I would greatly appreciate anyone who has experienced both the ER4S and RE272 to comment and provide comparison. I want the most accurate, neutral, and balanced universal regardless of price. I have read many reviews on the given IEMs, and well I'm hopeless at making the decision! I recently read the ER4S review posted on headfonia, and were described as not neutral because of being thin. "For all the good qualities, and clear, detailed presentation that the ER4 has, it is definitely not neutral. The sound is simply a bit thin sometimes, especially in the ER4S setting, and less full-bodied than real life sound. The emphasis on treble and upper mids, with relatively less mid warmth means that the ER4 is giving a raspy quality to voices more than what exists in the recording. The ultra fast attack and short decay is almost too fast." From my limited understanding, could the above be the consequence of poor seal? I get the impression of the ER4S being the more accurate phone, however understand the RE272 to have much larger soundstage?
