Not for everyone

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.

My ears are forever spoiled now!

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.

Amazing!

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.

Superior sound

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.

A gem of an IEM.

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 reference IEM, just not for bass heads.

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

Can’t Go Wrong With These

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.

Great accuracy and transparency

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.

Good!!

By CHOI M.

It's the new package!!

"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.

The ER4SR is a must have for discerning engineers, audiophiles, and consumers wanting the most accurate in-ear earphone available.
