A few days ago IÂ tackled the brand new Etymotic ER4-XR, and today I got my mits on the the new ER4-SR earphone. Â The SR version is a Studio Reference model, designed with critical listeners in mind. Â While taking design cues from the XR version, the sound is quite different.
Etymotic ER4-SR Review
The Etymotic ER4-SR comes packaged with a carrying case, a bunch of different eartips, and the earphones themselves. Â The cable is removable and utilizes an MMCX connection.
Comfort wise, the ultra-slim design of the earpieces goes a long way. Â The low-profile design is light, and doesn’t draw too much attention. Â While it can take some searching to decide on which eartips offer the best fit for you, once you’ve made your choice the rest is a piece of cake.
Oddly, I found these earphones had no problem staying in my ears. Â Normally, with most bullet-type earphones, I find my giant Dumbo ears will push them out after a few minutes of walking around, typing on a keyboard, or just breathing too heavily. Â However, thanks to all the triple-flange tips that the manufacturer provides, a good fit really does mean these things will stay in your ears.

The specifications reveal a headphone with a fairly standard frequency range, though not quite as much in the high end as some of the competition. Â Volume is also decent, but the impedance of 45 ohms may benefit from some amplification.
Low End
Relaxed but detailed, the low end on the ER4-SR is very tame. Â There is a decent amount of impact to the bass, but there’s also some good control here. Â As such, bass doesn’t bleed and the low end remains remarkably clean.
Mids
The midrange is characterized by a certain level of accuracy. Â Full of detail, there’s little distortion or compression to detract from the sound. Â Vocals are great, and instrumentation isn’t too shabby, either.
High End
Sparkling with detail, the high end can come off as a little bright at times. Â While rich and contrasting, the highs never get screeching or uncomfortable.
Soundstage
The soundstage offers an almost-tangible sense of depth and placement. Â While impressive for an in-ear headphone, it’s still not quite as impressive as the soundstage of its sister model, the ER4-XR (perhaps due to the dynamic nature of that headphone). Â Still, suffice to say this is an amazing soundstage to find in an earphone.
Overall Impressions
The Etymotic ER4-SR is well work the designation of a Studio Reference earphone. Â The fidelity, the details, the soundstage – this headphone packs quite the sonic punch. Â The fact that it is an in-ear model with plenty of tips and removable cables only makes it easier to love.
Recommendations
Is this the earphone for you?  If you’re a fan of Etymotics in general, these earphones may be worth a look-see.  With an updated, clean sound that doesn’t skimp on the finer details, the ER4-SR is as good for serious listening as it is for reference.  While it might lack the characteristic low-end “oomph” of the XR version, the relaxed low end will still appeal to many who prefer a less-bassy sound.
Is there a reason not to get these earphones? Â I suppose, if you want a sound that skews bright or warm, the ER4-SR really won’t be your cup of tea. Â In which case you could opt for something from Shure or something in the Westone UM Pro lineup.
