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.

    • Same as ER4XR, best noise isolation, excellent bass, smaller than any earphones you own
Size: Standard
I had the opportunity to try both the ER4XR and the ER3XR in person. During my test listening I could not discern a difference between the two. A DAC and amp do not add much to these, my phone drove them perfectly. Only the hardcore enthusiasts with lots of disposable income and bat ears will benefit from the expensive older brother. When I tried them both, my jaw dropped off an clattered to the floor. I ordered the ER3XR the second I got home. Looks can be deceiving! This is one BA pulling a triple, and you won't find such incredible sound in such a tiny package. Bass on these is much better than the reviews imply. It's no bass cannon, but it is punchy, deep, and satisfying. Mids and highs coexist in their fair share of space, and the best way I can describe the whole experience is "clean," and even as this is an IEM that sits closer to the eardrum than any other, the soundstage is not bad! Imaging is another high point here, and the detail retrieval can be incredible with most sources. I listen mostly to electronic bass music, but using them for rock, classical music, jazz etc. they performed quite well. In comparison to other IEMs they can be a bit hollow and occasionally "dry," but it's not too noticeable most of the time. They do a great job for both critical and enjoyment listening. The sound isolation paired with music makes me think I'm alone at the office if I close my eyes, and luckily for me the attached tips fit well. Removing/replacing them is a nightmare. The sensation of putting an earphone so deep into the ear canal (hold the sex jokes, kids) was not unpleasant for me, but I seem to see that being the exception rather than the rule. Keep your ears clean, keep on top of any infections, and you'll be fine. My complaints are with the manufacturing. They feel incredibly cheap. The wire seems flimsy. I've read that the connector can break easily, which is concerning as you need to apply pressure at the junction with the connector and body. The flange tips are, quite frankly, garbage. You will need to clean your ears weekly (at minimum) if you don't want to pull out three layers of wax, but that's expected with how deep these go. The case is lackluster, and doesn't even seem designed to fit the IEMs it is holding. Considering the price you are paying, and how few materials are needed to manufacture the product, I had to take away one star. Combined with the fact that Etymotic has proprietary tips and cables for unreasonable prices, they're lucky I didn't take away two stars. The sound is what redeems these two potential downsides. Also, there is no comfortable way to wear these around the ear, so be prepared to hear every single time the wire touches your clothes. I got away with looping the wire up and around my ear so that the wire hangs from the top, which is better than nothing. If you're looking for an excellent middle-of-the-road IEM, this is it. It keeps pace with many multi-BA IEMs at the same price point, and in some cases outperforms them. These are not your endgame if you can afford better, not by a long shot, but I have no plans to ever get rid of them for something else. TL;DR: Clean, balanced sound with bass worthy of the XR rating, but cheap manufacturing makes me question their longevity, and the price gouging on their proprietary parts does not help. Most people looking for balanced sound without shy bass will be more than pleased. I recommend these headphones. Try to wait for a sale if you can, part of the price you are paying is for the Etymotic prestige. ... show more

    • A nice step up from the HF5
Size: Standard

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. ... show more
