The Etymotic ER2s, sold at around $150-160+, are a pair of dynamically driven and uniquely tuned neutral IEMs that provide an excellent option for headphone jack enthusiasts. They have started to go on sale for $65 since June 21, 2021 making them very cost effective for what they provide in terms of capabilities. They are the newest pair in the RT lineup, and arguably also the least performing one though the comparison is technically unfair due to different driver types used.

Overview - Sound Quality & Comfort - The Etymotic is not very hard to drive; the elephant in the room is comfort as both the stock triple flange and double flange tips may irritate the skin in the ears, so they can't be worn for too long. Meanwhile the stock foam tips are more comfortable and sound better than the silicon tips, and make the Etymotic sound more open while having more bass and isolate better. They haven't gone through the official NIOSH certification, but the isolation should be the same as the HD-5 model.

Overview - Competition & Reputation - The ER2SE is the entry level IEM of the series. It takes a significant departure from the ER3 and ER4 in that it utilizes a proprietary dynamic driver but they are not the first dynamic driver IEM from Etymotic. Signature-wise, the ER2SE is similar to the ER4SR, and the ER2XR is basically an ER4XR with extra sub-bass tacked on. The ER2 is just so far ahead and makes some more expensive choices downright obsolete.

Drawbacks - There are complaints regarding the Etymotics making the ears feel very uncomfortable, but in general the deep insertion is familiar to most: mildly uncomfortable at the beginning but with excellent isolation and secure placement in the ear. There reportedly however is no soundstage, not much body, not much texture and impact, and not much air or snap for the highs. The bass also doesn't hit that hard and almost sounds like it rolls off on some tracks compared to other headphones, even though on sine waves there is an audible solid extension down to 25hz.

Recommendation - The Etymotic ER2SE is a great piece of hardware for enthusiasts, as they excel in sheer performance. Looks are not the earbud’s main focus; it’s the sound quality and the reduced price also helps. They offer a similar experience to the company’s ER4SR IEMs for less than half the cost, and going one step further, the cable and ear tips are easily replaceable. In terms of comfort, the earphones are designed to be inserted deep into the ear canal, and this is what provides the most output from the 35dB of isolation that can be achieved.

Build - The Etymotics retain great build quality and their 2-year warranty to boot. They are very skinny and go deep into the ear, and are made of metal for the most part. The cable is the usual and terminates into a standard 3.5mm jack.

Build - Comfort & Filters - The ER2 IEMs as well as the cable are very light and comfortable, though they require deep insertion into the ears when using the silicon tips. In order to get the best possible isolation, and because of this the filter is prone to getting clogged up with earwax requiring regular cleaning, which is fortunately not overlooked as the Etymotics come with a removal tool and an extra set of filters. The anodized metal housings are corrosion-resistant and feature uniquely slim nozzles that make the earbuds comfortable during long listening sessions.

Cable - The 4ft. cable is removable/detachable (MMCX) and as such can easily be replaced should it ever malfunction. Etymotic uses the same type of MMCX cable as audio powerhouse Shure, making it easy and affordable to replace the cable when needed. The MMCX cable terminates in a 3.5mm jack which is great for listeners whose phones retain the headphone jack. Alternatively, one can always plug the cable into a dongle adapter.

Drivers - New to this ER2SE IEM is the use of a dynamic driver; where before the BA drivers were used. The sonic qualities of dynamic drivers are very different than those of Balanced Armatures, though one thing remains the same: use of bad quality sources or files with these IEMs still results in bad sound. The ER2 sounds great out of a laptop, but when used with a dedicated portable audio player or headphone amplifier, the extra power and quality provided better soundstage and dynamic range overall.

Bass - The first thing of notice is that the ER2SE has a looser dynamic bass, while at the same time Etymotic has made sure that the new ER2SE still sounds very clear, clean, precise and fast. Bass is fast, but it’s more midbass than subbass, it isn’t as tight as the BA bass, and it doesn’t reach down really low in the ER2SE but that is a design limitation.

Drivers - With 15ohm Impedance and 96 dB sensitivity, the ER2-series is fairly easy to drive but a bit more difficult than its balanced-armature-driven bigger brothers. Dynamic driver earphones feel like they have a better characteristic sound, and take the same overall response.

Noise Isolation - Etymotic IEMs are known for their excellent noise isolation and these deliver a very impressive 35 to 42dB noise isolation when used correctly, and custom IEMs most of the time offer a -26dB isolation, making the Etymotic IEMs very special. The small-diameter nozzles and dense memory foam material do wonders for blocking out external noise. In order to experience similar isolation performance, it is recommended to spend some time getting a proper fit with the ear tips.

Soundstage - The soundstage width for a $160USD IEM is very good, but the width is better than the depth is. Soundstage surprisingly is as good if not better on these than the dt80 because it's not inserted as deeply with the foam tips and the driver is farther back in the shell.

Comparison vs. ER4 - For the price of the ER4 one could get an ER2SE/XR and something else. The extra detail retrieval from an ER4 is invaluable. For more bass and better timbre from buy the ER2. While the dynamic drivers used in the ER2 doesn’t present notes as cleanly or as precisely as the ER4, the timbral improvements in the ER2 are more appreciated especially in the bass.

Comparison vs. ER3 & Comparison vs. ER4XR - It has slightly more bass than er4sr and er3se, more natural tone, a bit more body and 3d image, but not as much upper mid and treble.

Comparison vs. Focal Elex - The ER2SE at $49 rivals Focal Elex in most aspects except bass quantity, imaging, soundstage, and dynamics, which make them a steal considering price difference. The timbre is not as good as the HD6XX's magical midrange, but it beats the Focal Elex in midrange tonality and timbre even after applying oratory1990's EQ preset to the Elex.

Comparison vs. Moondrop Kato - The bass quantity on the ER2SE is a little bit less than "just right". However, what is there is well-extended and textured. It's enough to support other elements in non-bass-heavy tracks and there's still quite a bit of bass in the bass-heavy ones. The Kato on the other hand had too much bass and darker tonal balance.

Comparison vs. Comply P Series - The Comply P series boasts more comfort and noise isolation. For other changes, the Spinfit CP155 with adapters is recommended for the ear tip entrance, in order to fit on the ER2SE nozzle, which is much more economical as Comply tips can get expensive.

Comparison vs. HD600 - The ER2s sound very similar to the HD600 with a fine DAC, though the HD600s are better, more open and more comfortable, though the two sound similar. They are a good use for $65 / $75. The ER2SE don’t have the same level that the HD600s have but are fairly similar in sound quality.

Comparison vs. ER2SE, Comparison vs. ER2XR, & Comparison vs. ER3XR - The ER2XR is a great all-rounder with most music, especially electronic music or anything that requires bass impact. The ER3XR is very resolving, but can sound a bit dark at times, so use of a 30ohm impedance adapter is recommended most of the time to turn them into a budget ER4XR. The ER2SE almost always gets overlooked because of the ER2XR. In a world without the ER2XR, these would probably get the most use.

Comparison: ER2SE vs. ER2XR - The ER2 comes first in the SE or Studio Edition. This version is the most neutral/reference tuned. Then there is the XR or Extended Response version which has a little more bass impact. The new ER2SE delivers clear, accurate sound using high performance dynamic drivers. The ER2XR provides impactful bass response while maintaining the clarity in the midrange and highs that Etymotic is known for. According to Etymotic, the flat frequency response of the ER2SE will appeal to sound professionals and audiophiles alike.

Comparison vs. ER4SR - Externally, the models are almost identical save for the model name and branding on the housings. The most notable difference between the earphones are that the ER2SE uses dynamic drivers, while the ER4SR uses balanced-armature drivers. For professional work the Etymotic ER4SR is a better investment as it’s used by sound engineers around the world. For recreational with some pro gigs sprinkled in, the ER2SE will go a long way.

Comparison vs. ER2XR - Both the ER2-SE and XR are faultless in terms of sound, as they provide bass and at just the right amount and manage to go very low without being pushed up. The XR version does, however, give a slight boost to the low end. There are a couple different sets of tips as well, while the cable is an mmcx connection, and is four feet long, defaulting into a 90 degree 3.5 millimeter with a step down. There are no problems with comfort and isolation of outside noises is good. The ER2XR is a single dynamic driver IEM, different from most Etymotics that use balanced armatures.

Comparison: ER2SE vs. ER2XR - The ER2XR begins rolling off base sooner around 200 Hz while the ER2SE remains flat until about 100 Hz. Treble tonality is worse on the ER2SE but with the foam tips it becomes very close to the ER2XR. Bass is never too much. The ER2SE is the best set with distortion figures at 0.112 at the highest at 20 hertz.

Price - Availability - The Etymotic ER2 IEMs go for $159,95 in the USA and €179,95 in Europe (Amazon Prices). Etymotic Research keeps slashing the prices on these and putting them on sale. This suggests that Etymotic are looking to appeal to a wider audience and along with the £170 and lower price tag.

Bass Enhancement - For more bass or a warmer sound it is suggested to use an external amp or warmer sounding, bass-heavier DAP to alter the sound. The portable player recommended to enjoy the ER2SE most is the Sony WM1Z, but for most in the market for this IEM, that might be a bit far stretched.
