between er2se and er3xr, which do you suggest?
either ER2SE or ER3SE choice is whether you want more tangible bass or clearer HF. I don't believe that bass hump of XR helps in quality.
ER2SE vs ER2XR
Just got ER2SE today instead of ER2XR that failed on me. This was tested on LG Q8 with quad dac which wasn't engaged fully due to low resistance of headphones. I use these with very deep insertion
ER2SE is clearly better for me than ER2XR. XR just have too much of midrange bloat from bass hump. Glad that I didnt replace ER2XR with another pair. Initially i got ER2XR as to have different presentation than my ER4 but i didnt like XR as that bass hump was too much and i just didnt like ER2XR altogether.
Both ER2SE and ER2XR are kind of difficult to drive due to 15 Ohm resistance.
ER2SE has good bass, clean midrange and slightly subdued HF (only slightly).
One cant really go wrong with ER2SE.
E2SE vs ER4P(I guess this is what I have with my current cable instead of ER4S original):
So ER4P has slightly less reverberant bass which is perceived as less bass.
ER2SE does not have that small rise in 1-2 kHz area compared to ER4P. As i understand this is a presence region, and hence ER2SE is slightly less "present". This presence is something that I really love and hence ER4P are better for me and ER2SE is in a way more "correct".
HF on ER4P is more "immediate" and you just "know" they are "there" and right how they should be. ER2SE have HF which is kind of more "schematic". They are there but more kind of artificial, i.e. of lesser quality.
Overall, ER2SE is a good buy and gives you more tangible bass at a cost of slight reduction in quality of HF.
I can only extrapolate that newer ER3SE and ER4SR continue providing same clearer/instant presentation original ER4 is known for.
