Choosing iem earphones often means balancing a focused wired listening setup against condition and cable compromises. The Etymotic ER4SR Studio Reference Earphone IEMs offer a clear case for listeners who want noise isolation and a 3.5mm connection, but the used condition and faulty original cable are central to the buying decision.
Quick verdict
At USD 134.99, the Etymotic ER4SR makes the most sense for someone comfortable with a used audiophile IEM and prepared to use the included black Etymotic official cable. The set is described as working great, and its listed noise isolation supports a more focused listening setup. The main caution is straightforward: the original silver cable cuts in and out, so the package is not equally ready to use with both cables.
Who it suits
This set suits a listener building a wired setup around a 3.5mm jack and an in-ear-only form factor. The included case is also useful for keeping the earphones together between listening sessions. Choose it when the studio-reference positioning, noise isolation, and working black cable align with how you plan to listen.
It is a weaker fit for anyone who specifically wants every included cable to function without repair. The silver cable has a stated connection problem, while the black cable is the dependable choice described here.
Etymotic ER4SR Studio Reference Earphone IEMs
The strongest reason to choose the ER4SR is the combination of its studio-reference identity, listed noise isolation, and replacement eartip filters. Those details point toward a purpose-built listening experience rather than a casual, feature-heavy earphone. The black official cable works properly according to the description, giving the set a usable wired configuration.
The concrete limitation is its used condition. The silver cable is supplied as well, but it cuts in and out and is presented as something that could be repaired rather than a reliable second cable. That issue matters more than the multicolor finish or the listed in-line control because it affects how simply the set can be used.
What stands out from the listed details
The ER4SR combines a 3.5mm jack, a 5ft cable length, in-ear-only form, noise isolation, and an included case. The cable arrangement is the detail to weigh most carefully: the black cable is described as working fine, while the silver cable has a specific fault. The recently replaced eartip filters are another practical detail for a buyer considering this used set.
Meaningful trade-offs
The decision is less about choosing between several sound profiles and more about accepting a used earphone with one dependable cable. The listed price reflects a focused wired option, but the cable fault should remain part of the calculation. If you are comfortable using the black cable and do not need the silver one repaired, the compromise is clearly defined. If a trouble-free original cable package is important, this ER4SR is easier to pass on.
Bottom line
The Etymotic ER4SR is a sensible pick at USD 134.99 for a listener who wants a studio-reference IEM with noise isolation, a case, and a working black cable. Its used condition and faulty silver cable are not side details; they are the trade-off that determines whether this set fits your setup.
