Etymotic Research ER2-XR Extended Response - In Ear Noise Isolating IEM Earphones with Detachable Cable
About this deal
Note: When there is no obvious treble peak (T1p) around the 4-5kHz area, SPL at 4400Hz is used as T1p value.
ER2XR is favored by those who enjoy the extra bass presence and body when listening to their music. The extra bass is done tastefully without turning the ER2XR into a bass heavy IEM. If you want an IEM for swimming, you need to be looking at an IEM that’s IPX8 rated, because nothing else will protect them with full-on swimming. Are custom IEMs more comfortable? The soundstage has decent width and a bit of height. Not very wide but i wouldn’t say they are overly constricted. Although similar in dimensions to the ER4XR, the ER2SEs don’t suffer from a very monitoresque presentation. They sound a bit more cohesive.If you’re looking for a great sub-bassy sound, without too much mid-bass bloat, then FiiO FH3 is your best choice. With great noise isolation, these are very good IEMs, and quite comfortable. FH3s have a quite natural and neutral sound, with exceptional sub-bass and excellent and sharp imaging. Overall, remarkable IEMs, and arguably the best bass for the price. Highlights: Etymotic IEMs need no introduction. The Etymotic ER2SE follows the Etymotic’s Diffuse Field (DF) Target. As a result, the sound will be flat, uncolored, and unforgiving. This also reflects to the technical performance as well.
With respect to comfort, don’t expect a particularly forgiving experience. You’ll always feel them in there. And for folks who are not used to this kind of fit, it can feel rather intrusive. But if you have an itch deep in your canal that you just can’t scratch, these buds should provide you with some relief. I’m not kidding. Earwax accumulation is such a serious concern that Etymotic even provides an extra pair of replacement stem filters for if and when the original ones become clogged. Etymotic’s target frequency response graph represents a “perceptibly flat” frequency response. Our goal is to have a flat frequency response curve when the music notes hit your eardrums. To achieve that, we need to account for the resonance inside the average ear canal, since IEMs bypass the outer ear structure. The result is the need for higher SPL in the 2-5k region (lower treble) for compensating said resonance. That is the reason for the “hump” in that region. Close to ruler flat impedance (15 ohms) ensures consistent tonality with various audio equipment regardless of the headphone output impedance.

This frequency range in particular makes the ER2XR an optimal choice for musicians. No sharpness, no unnatural “crispness” with respect to percussion. This is a fatigue free listening experience, even for those who tend to listen at dangerously loud volumes. Careful kids! The highs don’t feel blunted or shamelessly rolled off. But let’s just say that Miles Davis is tolerable when listening through these buds. Soundstage Let's get one thing out of the way first: the modded ER3XR sounds the same as the ER4XR. I already knew the FR was identical, but there might have been some difference in detail since they use the same type of driver but to a different tolerance. I didn't notice any difference at all, honestly. So the 4's advantages over the 3 are: nicer cable and more accessories, no need to mess around with bulky adapters. With deep insertion you’re as good as deaf. But even with my relatively shallow insertion, we get very good isolation. And there is no leakage.
With a better bass than the original, the Tin T2 Plus is a bit more broadly appealing and controlled. Easy to drive and a good set, with their pleasant tone they offer an outstanding value for the money. Super comfortable, with clear treble and strong but controlled bass. Highlights: Having one of the best prices to performance ratios, these DQ6 are a great experience overall, especially compared to EDX. With superb technicalities, great design, and good fit, DQ6 is highly recommended as one of the best budget IEMs you can get. If you enjoyed BLON but disliked the fit, or just want a step up, then HBB Mele might be an excellent choice for you. This is a great set that plays many genres well, especially drums and guitars, and is perfect for those looking for a warm-sounding set with a great timbre.
Only slightly more expensive than Aria, ER2XR blows most other budget IEMs out of the water through their focus on detail. With superb balanced tuning and isolation, the sound quality is incredible compared to other competing IEMs at a similar price. Highlights:
