Hey pianist! Just a/bed my bro's er4p and my sm3s.
My setup is this. DIYmod> copper lod with bg caps> ibasso p3 heron> er4/sm3.
Lets go to the
bass first.
For the er4, it hits quite low and it is definitely very tight. However, the quantity is a tad low for me.
The SM3 further improves er4s bass for me, by making the bass more full yet retaining the tightness and the ability to hit very low.
I prefer the SM3s for their bass
Mids.
Hmm.. how would i describe this. The ER4 does produce a good midrange, with good amounts of clarity.
The SM3s on the other hand feels more smooth and liquid, and it definitely sounds more full.
On a personal note, i'd go for the SM3s for their richer and fuller sound.
However, if i were given the er4s, i won't mind =D
Treble.
Ah, the treble on the sm3s are abit rolled off, but not so much till it's recessed.
The SM3s doesn't seem to have have the sheen or brightness of the er4's highs.
I definitely favour the er4 for the treble.
Soundstage & speed.
The SM3s and the ER4s are very much equal in speed, and personally i think the er4 is a wee bit faster due to it's tightness.
For soundstage, the er4 can't match SM3s 3d sound.
Comfort.
I would favour the ER4s for comfort. I have small ears so the sm3's sometimes poke at the side of my ears and it can be quite painful.
The ER4s stick out from my ear but it is definitely much more comfortable.
Conclusion.
Overall, the SM3s win the the ER4s with respect towards the bass, mids and soundstage.
For the treble, comfort and speed, the er4 wins it for me.
Actually, it's a matter of preference on sound.
I prefer a slightly warm-neutral sound, so i'd definitely go for the Sm3s.
My brother prefers a bright-neutral sound.. so he'll go for the er4.
And just to add in..
idk why but i always feel a slightly warmer tone gives an iem more musicality.
These are just my opinions, i hope none of you take it too seriously.
I'm not very good at describing sound, but i tried my best
ENJOY YOUR SM3S EVERYBODY!
