Etymotic Research ER4SR Review – Flat Design Meets Clean Sound

The Etymotic Research ER4SR presents itself as an update rather than an entirely new pair of headphones. However, don’t take the previous statement negatively, as this is a quality update from start to finish. Even though the pair’s flat response does hinder them a bit when it comes to the reproduction of bass-heavy music, audio purists would still be able to find the audio performance as welcoming as possible.

The Etymotic Research ER4SR Presents a Strong Build With a Sound Performance That Purists Will Love

The Etymotic Research ER4SR shares the same look with practically any other ER4 model you can lay your eyes on. Therefore, it might confuse some people if they’re not looking at the packaging they come with. Taking them out of the box, you will be able to see the in-ear models that are as thin as back tubes with cables attached to them. Speaking of cables, these are sturdily built, and it ends in a gold-plated 3.5-millimeter jack.

It should also be noted that the brand added in an MMCX connector towards each earphone. This means that the cable can be replaced should it go above and beyond the limits of wear and tear. Looking at the body of the earphones on the ER4SR, they have been upgraded to machined aluminum, and this is the answer of the firm for reports of some users breaking the earphones of previous models. Now, they feel sturdier, and it seems that they can hold even more than just the normal bumps and scrapes. What’s amazing is that even though it has been made to be more rugged, it still feels extremely lightweight.

When it comes to sound, audio purists would naturally be “eargasmic” over the performance of this pair of earphones. The audio quality is clean, and it makes an entirely large difference to the way the other models within the line can perform. When you feed it CD-quality audio, and you will immensely love the complexity and depth of the audio being delivered.

But it doesn’t mean that the Etymotic Research ER4SR is without any shortcomings. Sonically speaking, there is still a lack of bass, and low-end heavy tracks don’t offer much “kick” in them. Hence, the audio coming out of the pair is not fun, but clean. If you’re looking for a pair of audio-listening devices that you can bring with you on your workout sessions, these are not it. However, if you’re looking for a nice, clean offering to your tracks, then this is definitely worth checking out.
