Crafted from anodized aluminum with durable detachable cables, they provide up to 42 dB of noise isolation and a max output of 122 dB, making them ideal for professionals and audiophiles seeking immersive, detailed sound in a sleek, durable design. ## 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: 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! πŸ˜› 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! 😊 Review: Great sound! Really great! Blind buy great! - 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. ## Features - High performance Balanced Armature drivers are precision matched to within 1 dB - Transducers: Single high-performance balanced armature per channel. - Specially designed for uncompromising accuracy in the mid to high frequencies with a bit of extra presence in the lower end - Sleek, anodized, laser etched aluminum body and braided, reinforced detachable 5 ft.

As of my last edit, I have owned these for a week. Bottom line: These earbuds sound fantastic, but because of a comfort hurdle and not-great accessories, I don't think they're worth $350. Go for them if they're on sale. First, the positive: these are easily the clearest earbuds I've tried. Every sound is incredibly crisp and clean; I have no idea how Etymotic managed to get both good bass and no lingering rumble after, say, a drum hit, but they did it. As a result, these have an almost sterile, technical feel to them in a very good way: you'll hear every detail in any song you play or video you watch, provided you can get the fit right. This includes distortion or clipping if the recording was flawed. Speaking of fit, these will definitely take some getting used to. These feel more like earplugs than earbuds, and I had to spend several minutes switching between the provided ear tips (regular, large, and foam) before settling on one large triple-flanged tip and one foam. Even then, it's almost painful to feel the flanges digging into my ear canal. Hopefully, the earbuds will get easier to insert as I get used to them. As a final note, these things are so good at noise isolation that they can probably be used as professional hearing protection. That's no exaggeration; earplugs generally reduce noise by about 30 dB, and Etymotic claims that these earbuds reduce ambient noise by between 30 and 40 dB. They even include a warning to not use them while jogging outside, since you won't be able to hear anything around you. After a week of wearing, I've noticed a few minor problems in these earbuds. First, the slider that holds the earbuds under your chin is far too loose; it won't stay in place for more than a minute or two even if you're sitting still. The earbuds are also prone to falling off of the shirt clip quite easily. As Etymotic warns in the packaging, it's possible to insert the earbuds too far into your ear and lose the tip in your ear canal; the glue holding the foam ear tip to its rubber core is not especially strong, exacerbating the potential problem. On the plus side, these have gotten much more comfortable to wear as my ears get used to them. However, the problems I've noted are big enough together that I don't think these are really worth the $350 price tag. Maybe closer to $250 or even $225. Second edit: These are now my favorite IEMs. Etymotic is legendary for good reason. This would get a full five stars from me if the cable were a bit better; the MMCX connectors have a proprietary notch, so the only way you're recalling these is by sanding down the IEMs themselves. Not good, considering they're BAs. After a year or so of daily wear, the angled rubber on the MMCX connector wore through entirely; be careful taking these out or you could end up needing to spend $40 for a replacement. ## Frequently Bought Together - Etymotic ER4XR Extended Response Earphone - Etymotic ER Series 2.5mm Balanced Cable, Black - Etymotic Research Tuning Kit for ER Series Earphone with 5 Different Filters (ER-DAMPER5PACK) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/34358905-etymotic-er4xr-extended-response-earphone](https://www.desertcart.tw/products/34358905-etymotic-er4xr-extended-response-earphone) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-09-05*
