## Overview

The Etymotic ER2-XR In-Ear Monitors combine studio-accurate sound reproduction with an extended bass response, delivering 35+ dB of passive noise isolation through precision CNC-machined anodized aluminum shells. Designed for audiophiles and professionals, these IEMs feature a detachable MMCX cable and a comprehensive set of ear tips for a customizable, deep fit that ensures immersive listening in any environment.

## Description

The ER2XR is ideal for musicians and audiophiles looking for in-ear monitors that are easy to drive, with added warmth in the bass frequencies. The flat mids and highs, along with the emphasized bass of the ER2XR, will appeal to consumers and audiophiles who like a little more presence of bass. The ER2XR offers Etymotic’s renowned passive isolation, providing 35-42 dB attenuation. The ER2XR shells are made of anodized aluminum, CNC machined with extremely tight tolerances. Using a single dynamic driver allows for a very accurate IEM without the added complexity of crossovers, and helps keep the aluminum body small and slim. Included is a user-replaceable cable. Both ER2 models, the ER2SE and ER2XR, use the same low-impedance dynamic drivers. That means they are easy to drive, and no amplifier is required. The only difference between the 2 models is the tuning of the lower (bass) frequencies. The “Studio Edition” ER2SE is tuned to have a flat frequency response. The “eXtended Response” ER2XR is tuned to have an emphasized bass, adding 1-2dB to the mid-bass and 3-4dB to the sub-bass. 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. Accurate Earphone Reproduction When tuning in-ear monitors to accurately reproduce a recording of a live performance, our goal is for the sound hitting the eardrums to be identical to that at the original performance. To achieve this, the acoustic properties of the ear must be factored in. The acoustic resonance and horn effects of the ear change a flat audio signal entering the open ear into sound with a (2700 Hz) high-frequency boost, which is the same response heard at the eardrum in a typical ear. That is the reason for the “hump” in the frequency response graph, which assures the eardrums perceive a perfectly flat frequency response for all frequencies.

Review: Best earphones you can buy under £500 if you are competent at EQ enough to add a bass shelf. - Etymotic. ER2SE Review Cost:£70, supplier was desertcart UK prime next day delivery. The little iem that can. Equipment used : FiiO M11 Plus used as both A DAP and a transport for the Hip DAC 2 Ifi Hip. DAC 2 (connected to both phone and M11 Plus Included dongle to run from phone DAC (Poco F3) TLDR: get a set they're amazing! Packaging : Nice big box for good store presence, designed to hang from a shelf peg. Very good quality carry case, faux leather and faux suade. Inside the carry case were the goodies. A bag containing a filter removal tool and two extra filters in case the originals get blocked. Don't think I'll need them personally but nice to have. Also inside was two different sizes of triple flange ear tips a medium (I'd say) and a large. A pair of foam ear tips are also included, along with a great selection of double flange tips from small to extra large. The cable is MMCX but don't expect to be able to use your fave MMCX cable with these. They've customised the MMCX so that there's a slot you have to line up to get the cable to snap in. It's a shame as the included cable while Perfectly serviceable is a little microphonic. Fit: Try as I might I could not get on with either size of triple flange tips. They were OK in my right ear but wouldn't go deep enough to seal and.trust me these things go in really deep. Extremely deep. I ended up settling on the XL double flange. Fit is still extremely deep but not uncomfortable. You get a tremendous seal and the IEM almost completely disappears into your ears. I recommend trying the triple flange first and if you can't.get them to fit right do what I did and go for the double flange. I should have tried the foam tips for this review but avoided them as they seemed cheap and nasty. I'll try them and post if they're any good. Sound : The. SE are studio tuned so lack any real bass thump from stock. Vocals are forward, male and female both soumd smooth. Mids are where you want them and the highs shine without a hint of sibilance, just a sparkling performance. For the following tracks I listened to them both through the M11 Plus as a DAP and. The Hip. DAC 2 using both my phone and the M11 as transports. All music is.sttramed from Tidal in "up to" Master quality. For Example Dire Straits was unfolded to 192KHz. All the following were listened to using either Wavelet EQ or ifi XBass. Listening to Dire Straits (Money For Nothing) the guitar and drums including symbals are equally represented without one masking the other. They also excel at dance music. Listening to the best of Scooter the artificial instruments were silky smooth and really represented what I've heard from some good sets of speakers. My G by Ed Sheeran and Aitch when EQd or Xbassed sounds full and. Has a wide sound stage. Aitch's rapping and the backing track are perfectly balanced. There are layers to the back g track that are only apparent when I use the Etymotic. Psycho by Aitch and Anne-Marie really thumps with a decent EQ bass.shelf and lyrics and the piano are almost 3D sounding. My Humps.by Black Eyed Peas really thumps.with the right EQ (for me). The song is sub bass and semi mid bass heavy on the beat and this really comes through clean and snappy especially using XBass. XBass really works magic on these IEMs. Jucy by Doja Cat sounds the best I've ever heard. The bass line when EQd to my tastes is.forward but not too dominant. The female lyrics are lush and you can hear every word even when the bass line is at its peak. Simply a fantastic rendition of one of my favorite Tracks. Ed Sheeran Shape of You has.everuthing in its place. The high pitched.beat that runs.throuhh the whole.trsck is always present but doesn't take over like on for example. QKZ x HBB. A perfect balance.of instruments all in the right places and very clear lyrics. Lack of Bass (EQ) EQ and final thoughts.on source pairing: As I got the SE and. Not the XR (Xtended Range) the bass is extremely light. To cure this and bring the bass shelf up to my personal tastes I used Wavelet combined with Tidal to increase all frequencies from 80Hz to 300Hz. A boost of +3 on each really brought out some smooth non boomy bass. On the Hip DAC 2 I used the XBass function which adds a nice dollop of bass to anything plugged into it. They sound great through this DAC with. XBass! The lack of bass really isn't an issue as these respond to EQ so well. If you want more bass simply increase the frequencies of your choice. I did not find that doing this over shadowed the mids or highs and there was no bass bleed or boominess. As for source pairing I was supremely impressed by ifi's XBass. It just adds the perfect amount of bass and in my opinion wins over anything I've tried in wavelet including custom EQ files. I'll. Definitely be reaching for the HIP DAC 2 when using the Etymotic! My phone could drive these but at a very reduced maximum volume. It was listenable but left you wanting to turn it up a bit more. The M11 Plus with wavelet was decent and had plenty of power to bring out the best in these earphones. I did have to use higher volume. Than usual but still had 30 clicks left after they became loud enough for me. Conclusion: For £70 these things are a steal. As long as you're prepared for an IEM that inserts very deep in the ear canal you will love the sound of these. EQ is the icing on the cake. They respond so well to EQ ing a decent bass shelf. XBass. Is the star of the show though for me. I highly recommend this set as long as you're prepared to EQ if you like a bit of bass. I'm not bothering with Moondrop Variations. I've got such a versatile set in these ER2SE I'm going to save the £400+ and get the car a full service. What ever is left over I may try the latest interesting IEMs Like I did with QKZ x HBB. In short…… get the ER2SE or ER2XR, they're worth the money and with some tinkering they're honestly the best sounding set I've got in my collection. They beat Timeless and. Dioko hands down for detail retrieval. Get on desertcart and grab a pair. You have 30 days to return them if you don't like them. It's a no loose situation if you have a localised version of desertcart. Anyway, enough rambling. Get them!
Review: Fantastic IEMs, though comfort is ear-dependant. - Damn, I love these IEMs. They isolate amazingly well; airplane noise, screaming children, and other distractions disappear, even if you aren't playing anything through them. As for sound quality, they are fantastic; flat, but punchy. They are dynamic drivers, not balanced armatures like the ER3 and ER4, but they still have great technicality. I imagine comfort might be hit-or-miss for people though, since they have a deep fit which some people's ears might not appreciate. Also the included eartips are horrible, I've heard some people prefer them, I am not one of those people. Get the Comply P-series eartips; they might color the sound, but they are so much more comfortable; I often forget I'm wearing them. Cable noise can be an issue if you wear them down, since they conduct vibrations from your clothes, beard, etc straight into your ears, so I normally wear them up, hooking the wires over my ears, which kills any vibrations.

## Questions & Answers

**Q: Length of unit?**
A: Including the triple flange eartips but excluding the cable connector it's roughly 25mm (1 inch)

**Q: How do these deal with noisy/loud environments?**
A: These are perfect for noisy environments, you won't be able to hear any outside noise.
I was at an indoor Netball games and could not hear any of the high pitched whistles being blown at all.
These IEMS are really good.

**Q: Are these geared more towards professionals? Im a casual listener, but I'm looking to upgrade to something more serious than regular cheap earbuds.**
A: Speaking as a professional, yeah they have a pretty neutral and accurate sound with very good isolation, which I greatly appreciate because I can't stand exaggerated consumer-oriented sound signatures. It sounds better than anything else remotely close to this price. However, to achieve this great isolation and accuracy, you have to use those 3-flange tips and insert them properly (very deeply-as deep as they'll go). It takes a bit getting used to and may present a comfort issue for some, but for me, it wasn't a big deal and I got used to it quickly with no discomfort.

**Q: Are the foam or silicone flange tips more effective at noise isolation?**
A: I find the triple flange silicone tips better in my ears. But I have narrower than normal ear canals so the foam does not fit very well.

### ⭐⭐⭐⭐⭐ Fantastic IEMs, though comfort is ear-dependant.

### ⭐⭐⭐⭐ Outstanding, but prepare to abuse your earholes
*by A***W on 9 August 2022*

Ah the Etymotics, infamously known for their sound and value. However, be warned that you must be happy to plant these deep in your earholes. Renowned for their uncomfortable and intrusive fit, some will survive, but personally I could not manage and had to return. I thought I would have loved these, at the time I was using triple flange silicon tips on other IEMs so thought I was already used to an Etymotic style fit, but boy howdy was I wrong. Maybe it's my small ear canals, but I don't think I ever managed to plant these deep enough. However I certainly got close as they sounded amazing, quite bassy for a neutral IEM, but in a good way. Amazing clarity and tuning, slightly bassier than my Moondrop Starfields, and just really smooth and clean. Probably the best IEM I've used so far, just amazing presentation. However I couldn't live with them in the end and have since settled on Moondrop Arias. Worth trying for sure, but be prepared to return if you can't suffer the fit.
