I definitely prefer the ER-4S to the two Hifiman iems.
The Hifiman treble is peakier and on some songs the 262 can sound brighter and then on other songs, much darker. The 272 always sounded much brighter. It's the treble peaks that I attribute this to. The ER-4S has one of my favorite trebles (the F111 and K3K being my other treble favorites). It has better timbre and linearity than either Hifiman, and with reference plane fit, sounds pretty darn smooth.
The ER-4S also has one of the most transparent midranges I've heard and has very good layering and imaging within its head stage; although it can be a little hot in the stock configuration. I use red filters and actually eq 2.4k down -2db's. I prefer the 262 midrange to the 272 (but its been a while since I owned the 272 and can't really remember the reasons why I preferred the 262 midrange. The 262 midrange sounds wonderfully intimate with excellent tonality, I just think it lags behind the Ety's midrange layering and imaging.
The weak point and yet highlight of the ER-4S to me is the bass. It's diffuse field flat but I find that to be a little lacking in true neutral quantity. However the bass texture and detailing is some of the best I've heard. I do EQ it up starting at 30hz and have it tapper back in around 100hz or so for a more neutral presentation to my ears. I don't think the 262 has the texturing of the Ety but its bass sounds pretty fantastic with neutral levels imo and a very impressive natural tone. I hope I don't find the RE-600 to over do it here when it arrives. I can't remember a lot about the 272 bass but I remember thinking it was too lean at the time but looking at how it graphs, that perception was probably more based on its treble presence to me.
The perceived softer detailing and less articulate imaging in the Hifimans may be due to how they are damped. Some that have taken them apart have said they thought they were over damped and had better detailing and imaging after removing some of the filtering material. I've no idea if this is true or not, but the 262 does have softer notes than the Ety and my other iems, but I also think that's part of what gives them their special sound.
The ER-4S is not an easy one to find a simultaneous comfortable fit and excellent sound. It's taken me many weeks of experimentation to come a point of satisfaction. I imagine many give up and decide it's not for them and I can understand that. Plus diffuse field tuning might not be someone's cup-o-tea as well. However I love it and in many ways has ruined TOTL iems for me but it takes some EQ, comply p tips, a shirt clip and some patience to get there.
Anyway I think the 262 is great and forgotten iem. I sure hope the 600 can live up, and top, it's predecessors performance. Either way I plan on keeping one or the other in my small stable of iems.
