Review Summary

Sound: Its BA drivers shine in high and mid, however bass lacks a lot compared to Dynamic Driver IEMs. It is designed to be reference monitors not casual fun listening so the tuning is more flat than V-Shaped, which is good maybe for some studio and professional uses, not for every occasion. Build: Significantly step up from plastic build of ER3SR, these pair is solid, and cable is much sturdier too. Accessories: comes with loads of exchangeable tips and carry case. Comfort and Fit: They are not as scary as described in the user manual, "Lube before insert into ears", I got used to them just fine, but wearing them in a long session is not comfortable. Bottom line: I use IEM mostly on PC for music, game and movie. The sound from these IEMs are noticeably cleaner than regular Dynamic Driver earbuds, but not impressive. At this price, lots of hybrid driver IEMs are much better suited for casual daily use, the selection is massive.

Resolution is on par with IEMs above ~300 USD. Awesome deal here in Adorama. Thanks!

My ears got so spoiled by these Etymotic Research ER4SR. Passive noise canceling is awesome. Just need to get used to pushing in the IEM in your ears a bit.

Really wonderful IEMs, nicely accessorized. For me, it was worth it to get a balanced dongle DAC and cable to get the most out of them. After owning many Chi-Fi IEMs, my search has ended. Just get these and enjoy the music.

Fantastic sound. A bit weird at first in terms of comfort, but you get used to it. It's best if you don't pop them in and out of your ear a bunch. The low end is nice and tight and controlled, and the highs are never too harsh. Best sounding earbuds I've ever owned.

Fantastic sound, lightweight, comfortable, and, provides very good isolation. The comfort, sound isolation, and bass quality are dependent upon the tip selection and your ear anatomy but there are plenty of provided options and sizes to find what works best for you. They do require deep insertion in the ear which is where the variety of tips and sizes comes into play. This is my second Etymotic; the first being an ER4P which provided many years of excellent service. Etymotic is truly an excellent company.

Incredible detail and imaging. Slightly thin in weight in sub range. Unmatched isolation especially when using aftermarket foam tips.

Great new iteration of a classic in-ear monitor by Etymotic. Such a clear and unaltered presentation of sound. I’ve had my first pair for 7 years and they’re still working great; purchased these new ones to give them a try and compare to my old ones. I hope they last just as long! Precision matched drivers with a very specific frequency response curve to reproduce how our ears naturally receive and capture sound.

If you are looking for accuracy, look no farther. Fit is critical for these so if you are missing bass, the seal needs to be improved. There is a reason the Etymotic IEM has a reputation and these deliver. Having said that, the overall tonality might not fit everyone’s tastes. They respond well to equalization though. Overall, if accuracy and flat response is what you are looking for, the ER4SR will give it to you. I personally slightly preferred the subtle bass boost of the ER4XR but both are winners.

"Flat", good for Audio/Video Production
By Stephen L.
These are excellent quality, and the audio gain is great if you don't have an external audio amplifier and just want something loud enough, and "flat"(precise). Perfect if you do Audio/Video production and want something portable and on the go, which will help you fine tune the audio precisely for consumption.
ER4SR is Etymotic's new reference standard hi-fidelity earphone, for those who demand nothing less than the highest fidelity. The next generation of our long revered flagship earphone, the ER4S, the ER4SR delivers increased accuracy with greater sound output, or sensitivity. Like its predecessor, the ER4SR channels are matched within an industry-leading 1dB across frequencies from 100Hz to 10 kHz. The new ER4SR incorporates significant cosmetic and functional improvements, from a sleek, anodized and laser-etched aluminum body to the reinforced, user-replaceable detachable cable. The ER4SR is a must have for discerning engineers, audiophiles, and consumers wanting the most accurate in-ear earphone available.
In a Class by Itself
Etymotic invented noise-isolating, in-ear earphones. The ER4 MicroPro series earphones were the first earphones commercialized using balanced armature technology and are recognized as the world leader in response accuracy, to which all other earphones are compared. After more than 20 years, these reference-quality earphones are still the choice of serious sound engineers, audiophiles and musicians.
