I recently decided to invest in a new pair of IEMs for my portable music-listening needs, and after consulting the incredible summary of IEMs on this site, I decided on the R-50. More specifically, I purchased a pair of R-50Ms, because despite the extra $6, a headphone that I could use while talking on the phone provided a fairly tantalizing feature.
However, I've run into a little bit of an issue that is making me question my decision on the M variant. While the sound on these IEMs is incredible, the one thing that bothers me is the sibilance. On many tracks, particularly a 320kbps mp3 Pendulum album, a certain frequency of sound produces a very loud sibilance. I've read around and the main reasoning behind this is poor mastering/low quality source, so I tested them on some lossless files; while the sibilance was diminished, it was still slightly present.
My main concern is: is it possible that Rock-It Sounds lowered the acoustic quality of the R-50M compared to the R-50? The R-50 has some incredible reviews from some very knowledgeable people, so I'd be absolutely content simply knowing that my R-50M is no different acoustically than my R-50, and chalk my concerns down to inexperience with "accurate" audio reproduction.
P.S: An email from a service rep of Rock-It Sounds states: "Checked with the engineer, the acooustic performance will not be affected after adding the mic." I take this personally with a grain of salt considering the honesty policies of most companies.
Thanks for your time!
