Description
The ER3XR is a single driver in-ear monitor (IEM) known for its high sensitivity. Its anodized aluminum shell is CNC machined to precise tolerances, resulting in a slim and lightweight design. The use of a single balanced armature (BA) driver in the ER3XR provides accurate audio reproduction without the complexity of crossovers, while the included user- replaceable cable adds to its convenience. Etymotic IEMs are widely recognized for their outstanding passive noise isolation, which can reduce outside noise by 35-42 dB depending on the eartips used and their depth of insertion. This level of isolation is higher compared to most custom IEMs that provide around 25-28dB attenuation and foam earplugs that provide up to 32dB reduction. The ER3XR is an ideal choice for audiophiles and budget-conscious consumers who are looking for easy-to-drive IEMs that provide enhanced bass compared to the neutral ER3SE. Both ER3 models, the ER3SE and ER3XR, use the same high- sensitivity, low-impedance balanced armature (BA) driver, meaning no amplifier is required. The main difference between the two models is their tuning, with the ER3SE having a flat frequency response while the ER3XR offers an emphasized bass that adds 1-2dB to the mid-bass and 3-4dB to the sub-bass. The ER3SE is suitable for audio creators and musicians who want precise and neutral audio reproduction, as well as for prosumers who prefer to hear their music as it was recorded. On the other hand, the ER3XR is favored by those who want to enjoy the extra bass in their music while maintaining balance. Etymotic's target frequency response graph aims for a "perceptibly flat" frequency response. This requires accounting for the resonance inside the average ear canal and the need for higher SPL in the 2-5k region (lower treble) to compensate. The resulting "hump" in the frequency response graph helps ensure that the eardrums perceive a flat frequency response for all frequencies.

I have only had these about 30 minutes so far and will be amending my review as I break these in. But since no other reviews seem to be out there, I thought I'd put a bit of my first impressions out there. Though it is still early and these thoughts may shift some as I become more familiar with these. I'll also preface by saying I have not heard the ER4 range of headphones by Etymotic. But have owned the HF5 along with a collection of Sennhesier open back headphones and PSB closed back headphones. I upgraded to the ER3XR from the HF5. The HF5 has been my daily go to headphone to throw in my pocket and take on the go and to the office. I started looking into etymotic for passive noise isolation after listing to the "best" active noise canceling headphones out there and realizing ANC is garbage at best. If you are familiar with the HF5, the ER3 is a step up in the detail and separation in the sound. Maybe not a huge improvement for some, but it is very noticable to me on first listening. This is especially true in the treble detail. The biggest improvement however is in the bass region. The ER3XR clearly have a much needed bass boost in the low bass/sub bass frequency response compared to the HF5. It is very clean, separated and detailed bass and not overly bass heavy. Just gives a nice bit of increased support in the low end which was the main limiting factor with the HF5. The build quality is also significantly improved. The HF models have a plastic body and durable but thin cable. These are aluminum bodies with detachable cables which can be replaced. The cables are still quite thin but feel a bit more premium overall. This is nice as the cable seems to usually be the place where the HF models fail. In short, the HF5 are a durable but ultimately a "disposable" ....albeit costly, consumer product by build quality standards. These are approaching more of the professional build quality with replaceable parts so they should last longer. That should be enough of a reason to buy them over slightly cheaper monitors. If you are on a tight budget, go with the HF5 while they are on sale. If you can justify the additional $50-80 it is definitely worth it to go with the ER3. Based on the general impression so far, it recommend strongly that most people will really enjoy the ER3xr for listening to music. The flatter response of the ER3sr may be better suited for studio monitors or musicians monitoring live performances. Again, the slightly emphasized bass boost on the XR is far from what I'd call bass heavy. Definitely still very balanced sounding in my opinion but definitely not a flat response. One general comment/observation I've had on etymotic earphones is that they seem a little treble heavy at first and bass light with a very "digital" sound in general. They really open/warm up significantly after several hours of playback. I usually run them overnight with white, pink or brown noise playing through them to break the drivers in a bit. UPDATE #1: I've been using these for a few days now and absolutely love them. Based on the feedback I'm seeing online, these really are deserving of the SR series iem name. They are much more similar to the ER4 iems than they are different. It seems the biggest difference in these compared to the ER4 is that they are assembled in China instead of the US and the drivers are not matched to the same tight standards between balancing the left and right channels. However some of the Frequency Response graphs still show very good/great match between the drivers. The ER3 also appears to maybe have a bit more roll off in the high frequency response. this likely translates into slightly less upper high details. Comparing the bass of the ER4 and ER3 seem to rank from least bass to most bass ER4SR, ER3SE, ER4XR and ER3XR. In general the etymotic sound has historically been called cold as it emphasises treble detail and bass detail is light. The XR headphones have a raised bass response which caters towards a more mainstream audience response. The sound of the ER3XR may be a little too bass heavy for the purest/most balanced listeners. But I think most people will really enjoy the warmer sound signature of the clean and accurate bass. However, the ER3SE supposedly still has very good bass and should meet the needs of listeners really focusing on acoustic, jazz, classical or lightly scored vocals. The ER3XR is better suited for pop, rock, R&B and techno which would benefit from the stronger bass. Update: I did end up having a minor issue with these. Not long after receiving these I noticed a crackling/ popping sound coming through each driver when I was moving around.... with pretty much any source. So, it definitely seemed to be something related to the unit. I received a replacement pair and noticed the same exact thing. So, I contacted ETYMOTIC who was beyond accommodating in working to diagnose this. It was baffling to them also. In the end they could not diagnose what the issue was as both the original unit and replacement unit seemed to be within spec. At the end of this, they offered to send back my original unit with an upgraded cable (the ER4 cable) since the issue may have been associated with the cable. But this was never able to confirm since they couldn't reproduce the issue I was having. When I got the unit back, it seems the issue has been resolved. now I just have great sounding music and absolutely love these earphones. I'll clarify that I've used the unit in the same way as I did when noticing the crackling with both the original ER3 cable and the upgraded ER4 cable, but have not heard the crackling since. Long story short, Etymotics went above and beyond to try to help me out on this which speaks highly of their customer service and support. Sure you can buy cheaper brands, but you will not get this quality or support when you begin to have issues. Further these come with a 2 year warranty when industry standard is 6 months to 1 year for most earbuds if they have a warranty at all.

Very detailed listening experience. You can hear every instrument. Soundstage is not very wide but is present. Not for bass heads. These are not designed to rattle your head but rather provide an enjoyable listening experience. Etymotic has definitely made a valiant effort at creating an affordable entry level audiophile grade IEM. Do not expect $500 or $1000+ quality though. It's just not possible at this price point. If you are used to run-of-the-mill headphones by makes like Sony, JBL, Phillips, or any of the Chinese brands, you may not like these. I would say these are more of a fit for someone with a very discerning ear. Someone who is looking for a more "detailed" listening experience. Those who pair these IEM's with high definition audio files and a decent DAC will be rewarded with much enjoyment out of their listening sessions. These go DEEP into your ear canal, nothing like standard earbuds or most other IEM's. It will take some getting used to if you are new to the way these are inserted into your ears. Once you find the right tips and become acquainted to the feel of them though you will see the benefits to this design. The biggest plus being excellent noise isolation. Once the music starts to play every other sound just disappears. A blessing if quality music was your goal, a curse if you need to hear what's going on around you. I can't stress enough how important a proper fit is for these. Incorrect fit will result in mediocre sound reproduction. If you listen to these for a while and they sound terrible still you most likely do not have them fit properly. For me, the memory foam provided the best seal in my ear. I actually purchased the Comply tips that are made for deep insertion buds like these. These are wired earbuds, so keep that in mind before you buy them. If you are used to wireless buds and prefer the convenience of them these are probably not for you. If you are going to be moving around a lot or working out these are probably not for you. The wires simply rubbing against your shirt will be heard through the earbuds. Also, these will need some burn-in time. After about 5 hours they started to sound better. The longer you burn them in the better they get. After about 15 to 20 hours they were excellent. I have put well over 100 hours on my set and the sound is phenomenal now.

Primarily, I was looking for some headphones that would filter out noise in my work place. I've tried active noise cancellation headsets that costs several hundreds of dollars with the likes of Bose and Sennheisers, while they are good at canceling steady hums and environmental sounds and are quite comfortable, they have a hard time blocking people talking. I've tried many earbuds of various kinds, and the thing that really drew me to these were the reviews on how much noise isolation they offer, and I have to say, it's very good. They don't cancel the noise, they block them out. I hear almost no noise while sitting on the bus / train. I still can hear my office mates talking next to me, but at a much much manageable volume. If I put on a safety ear protection over that, there's no sound coming in through my ears. (My face and skull would still pass some noise through, but there's probably nothing I can be done about that except maybe wearing a full motorcycle helmet.) In order for these to form the best seal, you'd have to find the right sized tip and wiggle them into your ear canals pretty deep and tightly. Maybe some people would find them uncomfortable, but I find them tolerable. I've wore it for 4-5 hrs straight and they seemed fine. As for the sound quality, well, maybe that's where I'd take a star off if I wanted to. Initially, I thought they were pretty weak in the sound quality, but the more I listen to them, I'm beginning to think they're actually not bad. Definitely starting to win me over. What it is, is that these earphones sound like they are reproducing sound quite accurately. They have a very flat and uniform frequency response from well below 80Hz to 10kHz. It's just that everything's pretty even across the frequency ranges. Whether that's good or not, might be a personal choice, really. Depends on what you like to hear when you listen to stuff. I would say this though, if the XR version is supposed to extend the sound to lower frequencies, then I'd say I definitely made the right choice over the SE version because I think if the low end go missing, then these earphones would just be missing too much on the low end. After 10kHz, they really drop off of a cliff and you can't hear anything there, maybe even some static or noise if you crank up the volume. I can't tell if it's my amp or the ear phones, but either way, this setup I was using wasn't able to do it very cleanly. So that would be my one complaint. Other than the upper high end tones are just not there, I wouldn't say that these will be making thumping bass or ringing highs or reverberating mids, it might sound flat to you. If there's flaws in the source material or if you're more used to artificially equalized headsets (ehem, Beats *cough cough*) then you might not like them. If you use them outdoors when it's windy, rustling noise across the cables and things are amplified and carried straight into your ears, which can be quite loud. Cable are fairly easily tangled up, but they are the worst in this aspect.

These headphones a very sensitive which means that you will hear any little bit static that goes near them. Knock the cable a little, CRACKLE CRACKLE CRACKLE! If you plug it in to a laptop or cell phone then you will have to turn the volume all the way down to the minimum volume setting to not have your eardrums blown out. Turn the volume down to the minimum and you will hear constant static noises. I have one mp3 player with a low enough noise floor that these are usable with and they sound good, but then the cable brushes against my shirt and CRACKLE!

I like the quality and the sound isolation this provides. This is my second set in over 10 years. This doesn't give heavy bass, but not something that I am need. They just need to create a wireless version as the cord sometimes gets in the way depending on what I am doing - primarily when working at my desk.

The ER3XR is a great IEM. It's essentially 90% of the ER4XR but for way cheaper, especially if you wait for discounts. The sound is balanced with no major emphasis on any particular frequency. As it is the XR version, the bass is present enough for the mix of music I listen to from EDM to orchestral, jazz and the whole gamut. It will not move air like dynamic driver earphones, especially bassy ones, but the quantity, quality and extension are fairly good to me. If you want physical bass you have to look elsewhere. The mids and trebles don't have any particular points to note, other than it may a be a bit forward than other IEMs. I'm alright as it doesn't get to the point of shoutiness or sibilance. Cymbals and other stuff up the range sizzle fairly close to the real thing. You can tell it isn't the real thing, but I have heard more expensive multi BA iems that can't sizzle better anyway. The 3 main drawbacks in terms of sound is that it lacks that little edge in overall clarity compared to the ER4XR (only apparent if you listen to both), like its expensive brother Etys generally do are not very strong in soundstage size or imaging, and the single BA can sound congested on busy tracks with a lot of detail e.g. complex orchestral passages or rock/metal pieces. That said, the ER3XR became congested less easily than I thought it would be so I don't see this as a big problem. People get etys only for the sound but there are some things to note when getting these. Most importantly is the fit. These need deeper insertion than any other iem on the market so some may not like the sensation/find it uncomfortable. A way that lets you try out the fit other than a shop demo would be to buy Ety's Ety Plugs or ER20XS earplugs as the triple flanges are identical, since earplugs are a great option for noisy work environments or at loud music venues. Also note the MMCX connector has a notch so you need to search specifically for Ety-compatible replacements (not any regular MMCX cable). Lastly, not all sellers are covered by Ety's 2 year warranty, so check out Ety's website for official resellers. No comments on accessories, exactly as pictured on Ety's ER3XR product website. What the site does not mention is the channel matching standard. An Ety rep has clarified on HeadFi that these are matched similarly as the HF5, which is matched at 100hz within a specified tolerance. The ER4 series has much tighter matching across a frequency range rather than just one frequency, but the ER3 matching is plenty good for most users and is probably on par or better than most other IEM manufacturers. Couldn't pick up any issues when listening to mine. Those audiophiles who want more reading can search on HeadFi/Reddit on adding resistors to bring the FR closer to an ER4XR, matching (mentioned above) and other discussions.

Audio quality is excellent. Very clear and crisp sound with enough bass. I bought these for decent sounding earphones when travelling, particularly flying. Passive noise isolation is by far the best I have found on any earbuds. This may vary from person to person and you have to be able to live with fairly deep insertion of the buds which some might find uncomfortable. I have used on several flights as a more portable alternative to bulky anc over ears phones. So far I am happy with them and have used for at least 3 or 4 hours at a time. My one major complaint is that the right channel has been failing intermittently. I can usually wiggle the wires around to find a position that works but it is immensely annoying. These are just over one year old. I would return if still in warranty. A pity because they are great in most respects.
