## Overview

The Etymotic ER4XR is a professional-grade in-ear monitor featuring a single balanced armature driver precisely matched within 1 dB for exceptional audio fidelity. Its CNC-machined anodized aluminum body houses a durable, detachable 5 ft. braided cable with MMCX connectors. Offering industry-leading passive noise isolation of 35-42 dB, it delivers immersive sound without the need for batteries or active noise cancellation. Designed for audiophiles and professionals seeking a slightly bass-enhanced yet accurate sound signature, the ER4XR is compact, comfortable, and travel-ready with multiple eartip options and a premium carrying case.

## Description

The ER4XR is a high-performing in-ear monitor with a single balanced armature (BA) driver, making it highly accurate and compact. The anodized aluminum shells are CNC machined with tight tolerances and are paired with a durable, replaceable cable. Known for its strong passive isolation, the ER4XR offers 35-42 dB of noise reduction, making it ideal for audiophiles who seek an immersive audio experience. The right and left channels are matched within 1dB across frequencies, providing a consistent and enjoyable listening experience. The ER4XR offers a "fun" sound signature with added bass compared to the reference model, ER4SR. ER4SR is ideal for sound engineers and audiophiles who prefer a flat and accurate sound reproduction, while ER4XR is for those who enjoy a bit of added bass presence. The frequency response graphs are designed to deliver a perceptibly flat frequency response that compensates for the resonance in the ear canal. The target frequency response was developed by Etymotic based on over 20 years of human hearing and acoustics research. Each ER4SR and ER4XR comes with a channel-matching compliance graph.

Review: You've never had isolation like this before - I'll say this first, there is a learning curve to them, your ear will adapt and it will like it. First few weeks were sort of unpleasant with them in my ears, but after that break in time it all became worth it. With them just in your ear and no music playing they're like very good earplugs, very useful for traveling, exceedingly useful for traveling, best thing is that you don't need to charge them, they're small, wired, and never run out of battery! And we haven't even gotten to the point of the product yet hahahaha, the sound, oh my... As soon as sound starts playing the outside world vanishes, everything but a jet engine right next to you might as well not exist, that and maybe gunshots or loud sudden noises. For almost every other situation, they offer unparalleled noise isolation. You might be familiar with noise isolation in its active form, its what all the nice bluetooth headphones and earbuds (airpods) use, and its quite nice, its nice that you can modify it and adjust its intensity. But even on an ANC's highest level, it can barely hold a flame to what these things can do passively (no fancy programming required!), its hard to imagine so my words will only do it partial justice, but I can't stress it enough, you've never had isolation like this before. If you're looking for the ultimate study, focus, silence, earbuds, you may not like it but this is about as good as it gets. AND WE HAVEN'T COVERED SOUND YET. They sound amazing, super crisp, insanely crisp, some may say its a bit clinical of an experience, idk, I like it. I think theres enough bass, although I can see how one may want more. You'll hear details that you've never noticed before in music, songs youve heard a million times before. Obviously soundstage is going to be compromised for something that is halfway into your ear canal, but they still put down great numbers. Other people have done more in depth reviews on the stats than I'll provide here so go check those out before you buy if you care about the numbers. While they may be about as good as it gets for noise isolation, I won't deny that its not exactly the case for sound, ofc there are better sounding headphones out there, especially at this price point. But I think overall, for the packaged deal, these tiny little things, that fit in a cute little pouch you can easily slip into any pocket and not have a weird bulge, these little earbuds that you can just forget about and throw them in your bag when you're leaving without worrying about them not having enough charge, these little monsters you can put in your ear and drown out the world all while enjoying world class quality sound, these earbuds? They're worth a buy
Review: Etymotic ER4XR vs Etymotic hf3 vs Shure SE535 - I felt compelled to write a review of these IEMs having obsessed about them for months now. They are all very good! They should be for the price! Haha. So where do I begin? Most important, above all is sound quality. They are all good with certain signature differences. I have been using Etymotics for years. Using the Etymotic hf3. Excellent overall. Very accurate. Just not a lot of punch or presence to the bass. It's there but doesn’t hit you over the head. I tried other brands of phones and found them to sound inaccurate or sloppy. I had some older Shure IEMs and I wanted to see if their newer models sounded better. I tried the Shure SE315. and the Shure SE425. Didn’t sound as good as my old model. Back they went. Decided I would need triple drivers to get a significantly better sound. Bought the Shure SE535. Lots of money! And wow! Very impressive! Having come from the Etymotics, the sound is very different. Its warmer and slicker sounding. The voice range is a little less forward, which may be simply because the bass presence and detail is huge compared to the Etymotics. The Shure SE535s are very entertaining to listen to. More so than the Etymotics. With the Shures, you feel more like you are being washed with music. With the Etymotics, it just feels more like you are analyzing the sound. There is way more punch and space to the sound in the Shure SE535s. Almost too much punch on certain tracks. 😳 Let me go back to the Etymotics. I tried out the Etymotic ER4XR and the Etymotic ER4SR. Very little discernible difference. Maybe slightly more bass presence with the XR. I have been using the Etymotic hf3 for many years. In my opinion, the hf3 sounds as good if not better than the ER4XR. The reason is that the ER4XR has a higher impedance than the hf3. On an iPhone, you have to turn up the volume essentially all the way to get the full sound out of the ER4XR. This is not the case with the hf3s. They are good at 3/4 volume. Makes a significant difference! Other than that, there is maybe a slightly discernible improvement in separation on the ER4XR. But I mean slight. Overall the hf3 sounds better. And they cost way less! And there is another point. Comfort. This is a tricky issue when it comes to IEMs. After trying to use the triple flange cone tips, I gave up do to discomfort and the scariness of sticking a little plastic Christmas tree up your ear canal. I found that using the cylindrical foam tips created just as good a sealed fit and bass response as the "tree" did. So that is what I use. The Soft Flex Sleeves are also an excellent alternative. Really good isolation and amazing bass response! That brings me to the difference between the Etymotics and the Shures. The Etymotics are simply more comfortable. The drivers are smaller and weigh less than the Shures. Less of a pull on your ear structure. Shures design is supposed to route the wire over and behind your ear. I find this distracting and annoying in addition to being uncomfortable. My solution is to let the wires remain in front of my ears, hanging down in front of me. Much more comfortable. (See photos) This however, necessitates using a shirt clip to cancel out the weight of the cord pulling on your ears. I bought some from desertcart. Works well to make the phones as weightless as possible. With the Etymotics, this is less of an issue because the earpieces weigh so much less and the foam goes straight into your ear canal. The Shures have to kind of sit on your ear structure. Not so comfortable. I'm hoping over time that I will be bothered less and less by this slight pressure. It is worth it to get the sonic results that the 535s deliver. Back to the Shures. I payed a very large amount for the 535s. For me they are worth it for the spectacular performance they deliver. I can only imagine how nice the Shure SE846s sound. I just couldn't bring myself to spend one thousand dollars on IEMs. I do after all have a family to support! 😛 So I am happy I have both. I will probably usually use my 535s for my daily commute to Manhattan. But it's nice to switch out to the Etymotics for a lighter more Spartan sound signature. Hope this review helps some of you out there. With streaming music, it's like being a kid in a candy store every day. And with these headphones, You can hear the candy really really well! 😊

### ⭐⭐⭐⭐⭐ Great sound! Really great! Blind buy great!
*by R***E on June 6, 2024*

Background: This is my 1st pair of BA-only earphones. I have other earphones that I really like, but those are dynamic driver-only or hybrid. These sound heavenly. So beautiful. I have had them over a month now and they still give me that WOW factor when I switch from another pair. They are so detailed and so smooth. The mid range and treble are just so clear and so slick. I can hear tons of details. Vocals (make and female) sound balanced compared to other instruments and so natural. The treble is clear and sweet, and it has a great "bite" to it when a punky electric guitar is playing. Nile Rodger's guitar sounds like a bell on these. All genres sound good on these, and I am impressed with how they handle congested tracks and how easy it is to follow individual instruments in a busy song. This is the kind of set that makes you listen to all your music over again. The bass is definitely present. I was worried that the bass wound be weak or thin, but these have punch and slam when it is present on the recording. These are neutral-tuned earphones, so they are not going to loosen your teeth, but the bass is certainly NOT missing. If you cannot hear the bass, your fit and seal is not correct. It took me two days to find the bass on my ER4XR, turns out I just had to experiment with all of the eartips and get the seal correct. Just watch the video from Etymotic about how to insert these and the bass comes alive. They take EQ really well. You can easily make them basshead level without distortion. They are good for hip-hop...it's fun to hear so much detail in the samples. I'm not a gamer, so I cannot speak to how they perform with video games. I have never tried to watch TV or movies with these either. About that fit, honestly...it is not comfortable...especially when you first put them in. They are tolerable though. Each time I put them in, It takes me a minute to get the seal right...then after about 3 minutes of discomfort I don't notice them much at all. True, they are the least comfortable of all the earphones I have ever tried, but I HAVE fallen asleep with them in my ears, so they are NOT THAT BAD. My setup is: ER4XR connected directly to the 3.5mm jack on my cheap android phone. No external amp, DAC, DAP, or dongle. These are easy to drive. I love these. When I hear a new song while I'm out, I cannot wait to get home to my ER4XRs so I can listen to it "properly." These sound SO good to me. If these ever get lost or broken I will get them again. These are my favorite earphone right now.
