I was able to spend a couple of hours. Felt night and day on use. Preferred the SD5.
These are just thoughts, would not consider myself an expert so keep that in mind
- Fit no doubt InEar has this figured out
- The fit helps with seal
- The Mid and High territory seem to be kind a similar, I did hear some peaks or crossings on some tracks that I felt the SD also handled a bit better, weird for me I heard some EDM and ES for some reason gave me a sensation that it represented better the beats on thisbtypeof genre, only 2 tracks
- Bass wise I like SD, the ES felt a bit shallower.I changed tips and got some seal, but the body was not there.
