    Etymotics Research is a well-established company researching and developing products and tools for safer hearing and their ER4 series of in-ear canal phones have been around for a very long time with great popularity and success.

    A few years ago, they released the latest ER4 series, the ER4SR (Studio Reference) and ER4XR (Extended Response), using their latest balanced armature driver. This was soon followed by ER3 series, which reduced the impedance and moved its production from the USA to China and reduced the price by half while providing similar sound profiles in both the SR and XR versions, named ER3SE (Studio Edition) and ER3XR (Extended Response).

    Earlier this year, the ER2 series was released to market. The unique different between the ER3 and ER4 with the ER2 is the balanced armature style driver has been replaced with a more traditional dynamic driver, in a tiny micronized fashion to fit in the same shell design as the ER3/ER4 series.

    THE ER2 SERIES

    The ER2 series comes with the same accessories as the ER3 series – a carrying pouch, a set of small and large tri-flange silicone tips, a set of foam tips, and an extra pair of filters and a tool to remove them. Like the ER3/ER4, the cable is detachable and features an mmcx connection just like the formers. The housing and cable split are now in a royal blue color as opposed to a more traditional black and gunmetal colorway.

    ER2 DYNAMIC DRIVER

    Users of the BA versions of the Etymotics will be right at home with the Eytmotics house sound – a Diffuse Field signature that essentially puts every frequency on a level playing field – some may call it neutral. It’s a great reference sound signature that is easily appreciated and maybe somewhat boring.

    The dynamic driver versions are actually quite nice. They add a more natural tonality to them, with ever so subtle changes in how the ear phones sound in your ear, despite measurements of the ER2 and ER3 Studio Editions being quite similar. The ER2SE does have a slightly warmer sound than the respective ER3 and ER4 siblings, and this does help make the organic sound of the dynamic driver shine a bit. The slight bass boost also gives a little more energy all around, while still being a bit sterile in nature.

    [​IMG]
    The XR version features a bigger bass boost than the XRs of the BA variety and with the dynamic driver in tow, the warmer, richer sound is very engaging and just the right amount of gain that is needed to turn the sterile SE version into a musical gem. The ER2XR also has a slightly more noticeable wider soundstage, which helps a little bit with congestion.

    The XR and SE pack a lot of detail retrieval and resolution into a small form factor, and outclass anything at $129 and easily above other price points until you, of course, reach its older siblings. And while the BA versions do have quite good technicalities and an airy sound to them, I still prefer the dynamic ER2 over them for their more natural tonality and timbre and their improved bass and low-end performance.

    The XR in particular has a thicker sound than what I was expecting, and even has some subbass rumble to it. The mids aren’t quite as forward and clean as the SE model, but both still perform will with respect to their traits. The dynamic driver is quick and fast, and cleaner than I would ever expect one to be at the price point it’s selling for, especially for a well-established respected company like Etymotics.

    ISOLATION

    For isolation, I put the ER2 to the test on the Fourth of July. With fireworks booming and blasting everywhere around me outside, I stuck the ER2, tri-flange tips, in and it muffled all but the most loudest and most illegal of fireworks. And that was with no music playing! These are great for noisy environments. They won’t cut out everything, but they’ll do a lot better job than most passive and active noise cancellation systems. With a little faint volume music playing, all the fireworks celebrations vanished. Magic.

    OTHER COMPARISONS

    I wanted to touch base with a few other IEMs in this price range that I really like a lot. Namely, the Moondrop Kanas Pro and the BGVP DMS. They are considerably different than the ER2 but worth looking at.

    Moondrop Kanas Pro
    First the Moondrop Kanas Pro is a more Harman Tuning than the Diffuse Field tuned ER2SE, so right off the bat, you’re going to hear a lot more bass quantity and more recessed mids in the Kanas Pro than the ER2SE. The XR variant, however, does have a warmer bass boost, and actually results in a richer mid section that’ll make male vocals more thick and natural. The Kanas Pro will beat both variants in terms of soundstage and air, and gives it a much more open space. That said, the ER2s meet or exceed the Kanas Pro in details and just general tonality.

    BGVP DMS
    The BVGP DMS is almost the complete opposite, but I really like it. It’s open-back and does not seal at all. So that’s a night and day difference from the Etymotics. But the DMS has a lot more “fun” factor in that it boosts both the bass and the treble response and provides a very open soundstage that can make your feet move, much more easily than the more sterile and toned down ER2 series. This is a complete 180 from the ER2 series and both would compliment each other quite well for a fun and an analytical IEM duo.

    OVERALL

    At the end of the day, this review has kind of gone a little bit all over the place, and maybe I can blame that for writing bits and pieces of it over a week’s time instead of coherently writing it in a shorter period of one or two sittings. Luckily, I don’t need to say a whole lot more other than that everyone should try one of these models out. They may surprise you with how much better they work than many active noise cancellation headphones out there, and then shock you again with how good they actually sound for a great price. They do go heel to heel and perhaps best the ER3, and could even be preferred to the ER4, depending on sonic preferences.

    You may ask, which do I prefer?
    I prefer the ER2XR over the SE. The bass boost provides are more enjoyable warmer experience that I think will benefit for plane and train travel, as well as just giving a more relaxing listen. The SE does a lot of things right however, and I think many will enjoy the more analytical nature of it as well.

    Etymotic's first serious dynamic driver

    Pros - Maintains the clarity Etymotic is known for
    Weightier in the low end than its BA counterparts

    Proprietary MMCX connector
    Etymotic's new ER2 series

    Etymotic has released two new IEMs. The ER2-SE (studio edition) and ER2-XR (extended response with a tiny bit of extra bass). Today, we're looking at the ER2-XR. Price is $160 (RRP) at the time of testing. Purchased with my own money.

    IMG_3389 copy.jpg

    Etymotic has been doing research on hearing aid and in-ear monitors (IEM) for decades so it needs no introduction. Its latest products include the ER3 and ER4 (XR & SR) series, all based on a balanced armature (BA) driver. While Etymotic has previously made some dynamic driver (DD) earphones, such as the MK5 and MC5, these models have been priced relatively affordably and have not been able to compete with their flagship ER4 series. The new ER2 series, priced at $160, are based on a dynamic driver and are perhaps their first serious attempt to make a solid mid-range DD offering. If you are new to DD vs BA drivers, you can find some basic details here.

    Build

    The ER2-XR's housings are metal earpieces with anodized finish, identical to the ER4 and ER3 series. The build is sturdy and I have no complaints here. However, the cable, which seems to be identical to the ER3's, is quite thick around the ear and generally not very comfortable for over-the-ear use. I would suggest getting a ER4-06 cable - the one that ships with the ER4 series - as a replacement. Please also note that Etymotic uses a proprietary MMCX connector and this will not directly work with any MMCX cable. A final thing to note here is that the ER4 (XR and SR) series are made in the US, while the ER2 and ER3 are made in China.

    Accessories

    Identical to the ER3 series. Less accessories than the ER4 series but still adequate. Includes both small and large tri-flange clear silicone tips and Comply foam tips. I personally prefer the large silicone ones as this allows me to get a good seal. The ER4 series come with a personally signed copy of the IEM's individually tested frequency response, channel matching, THD, etc, which you don't get with the lower priced ER2 series.

    Fit

    If you are a new Etymotic user, these may not be very comfortable during the first few weeks. Applying a bit of saliva or lubricant to the tips may help a lot in terms of putting them in and getting a good seal. For good or ill, the dirtier the tips get (wax), the more comfortable they become. Once you get used to that, comfort is unlikely to be an issue. However, sleeping with them will not be ideal, given the fit. Wearing them over the ear completely eliminates microphonics so I highly recommend that, despite the fact that they are seemingly not designed for such use. I personally use the ER4 series cable on the ER2-XR as it's longer and considerably more comfortable when worn over the ear. A final thing to note is that sound is heavily dependent on fit. Make sure you select the right tips and you get a good seal. The way I do it is I push the tips as deep as possible and then drag them back a little bit until I hear a popping sound.

    Isolation

    As good as it gets. Etymotic lists the ER2's external noise isolation as 35-42 dB and I found no difference between these and the ER4 series. Etymotic has confirmed that despite these being DD, there are no external vents to the outside world. Completely blocks all sound around me when I get a good seal. No sound leakage to speak of. If you are like me and you are overly concerned about disturbing others, these would be great for you.

    Sound

    Very easy to drive. Bassiest Etymotic IEM I've tried to date - this includes the ER4-XR, ER3-XR and MK5. It is warmer and has considerably more sub-bass than its higher-priced BA counterparts (deserves the Etymothicc label). That said, as the old saying goes, don't expect a bass-heavy Etymotic (nowhere near e.g. IT01 in terms of bass quantity or having a V) and this added bass is all tastefully executed. Bass is well controlled and there's little or no bleed.

    The rest of the frequency response is quite typical for an Etymotic earphone and you still get a ton of detail and good separation, plus the clarity Etymotic is known for. The treble is perhaps a touch more recessed compared to the ER4-XR. Relative to the ER4, the ER2 may sacrifice a tiny bit of detail in the upper range. On the positive side, the ER2-XR is arguably more enjoyable on bass heavy tracks due to the extra punch in the low end and the natural decay of the dynamic driver. Soundstage is adequate but don't expect too much from an Etymotic in-ear in this regard. Overall, I have very little to complain about, given the price.

    Conclusion


    For $160, the ER2XR is a steal. This is a very competent IEM with significant amounts of detail and it's arguably better value for money than the ER4 series, considering the massive price difference. Its low end is punchy and engaging, making it well suited for modern music. If any Etymotic IEM I've tried so far deserves the 'fun' label, the best candidate for this would be the ER2-XR. Despite the cable not being ideal, the ER2-XR definitely gets my recommendation as one of the best IEMs in this price range.​
