ER4XR is Etymotic’s in-ear monitor for those who demand nothing less than the highest reproduction accuracy in the midrange and treble frequencies, but prefer a tastefully added bass presence.
The ER4XR right and left channels are matched within an industry-leading 1dB across frequencies from 100 Hz to 10 kHz.
ER4XR is the highest-performing single driver in-ear monitor. The IEM shells are made of anodized aluminum, CNC machined with extremely tight tolerances. Using a single Balanced Armature (BA) driver allows for extremely accurate IEM without the added complexity of crossovers, and helps keep the aluminum body small and slim. The included high-quality user-replaceable cable is reinforced and twisted, to improve longevity and durability.
Etymotic IEMs are world renowned for their class-leading passive isolation, providing 35-42 dB attenuation (depending on ear tips used and the depth of insertion). For comparison, most custom IEMs provide approx. 25-28dB attenuation and foam ear plugs attenuate up to 32 dB. The ER4XR is a must-have for audiophiles and consumers, looking for very accurate in-ear monitors with a taste of added bass, for a more “fun” sound signature.
Which ER4 is right for you?
Both ER4 models, the ER4SR and ER4XR, use the same Balanced Armature (BA) drivers. The only difference is the tuning of the lower (bass) frequencies. The ER4SR, being the “reference” model, is tuned to be as precise and flat as possible. The ER4XR, being the “fun” model, is tuned with added bass. As you can see from the frequency response graphs below, ER4XR adds 1-2dB to the mid-bass frequencies (below 200Hz) and 3-4dB to the lower-bass and sub-bass (below 100Hz). The rest of the frequencies are practically identical.
ER4SR is ideal for sound engineers and mixing technicians who must have a precise and accurate sound reproduction across all frequencies. ER4SR is the IEM of choice for audiophiles and consumers who like to listen to their music exactly the way it was recorded.
ER4XR with its tastefully added bass is favored by audiophiles and consumers who prefer a little extra bass presence when enjoying their music. This model is not bass heavy by any means.
Frequency response graphs and Etymotic’s target:
Etymotic’s target frequency response graph represents a “perceptibly flat” frequency response. Our goal is to have a flat frequency response curve when the music notes hit your eardrums. To achieve that, we need to account for the resonance inside the average ear canal, since IEMs bypass the outer ear structure. The result is the need for higher SPL in the 2-5k region (lower treble) for compensating said resonance. That is the reason for the “hump” in that region.
The target curve that Etymotic is using for tuning our IEMs differs slightly from the Harmon preference curve. It was developed in-house more than 20 years ago, leveraging on our human hearing expertise and acoustics research.
Accurate Earphone Reproduction
When tuning in-ear monitors to accurately reproduce a recording of a live performance, our goal is for the sound hitting the eardrums to be identical to that at the original performance. To achieve this, the acoustic properties of the ear must be factored in. The acoustic resonance and horn effects of the ear change a flat audio signal entering the open ear into sound with a (2700 Hz) high-frequency boost, which is the same response heard at the eardrum in a typical ear. That is the reason for the “hump” in the frequency response graph below, which assures the eardrums perceive a perfectly flat frequency response for all frequencies.
Channel-Matching Compliance Graph supplied with each ER4SR and ER4XR.
| Which ER•4 is Right for You? | Included with every pair of ER•4 earphones is an industry-exclusive channel-matching compliance graph, signed by the Etymotic engineer who precision matched and custom tuned the balanced-armature drivers. ER4SR is Etymotic’s new reference standard hi-fidelity earphone, for those who demand nothing less than the highest fidelity. The next generation of our long revered flagship earphone, the ER4S, the ER4SR delivers increased accuracy with greater sound output, or sensitivity. Like its predecessor, the ER4SR channels are matched within an industry-leading 1dB across frequencies from 100Hz to 10 kHz. The new ER4SR incorporates significant cosmetic and functional improvements, from a sleek, anodized and laser-etched aluminum body to the reinforced, user-replaceable detachable cable. The ER4SR is a must have for discerning engineers, audiophiles, and consumers wanting the most accurate in-ear earphone available. ER4XR is the earphone for music lovers and hi-fi enthusiasts who want uncompromising accuracy in the midrange and high frequencies, but appreciate a bit of extra presence in the lower end. Like the ER4SR, the ER4XR is built with precision machined, anodized and laser-etched aluminum bodies and features user-replaceable detachable cables. The ER4XR also incorporates the stringent channel-matching standard used in the ER4SR. The ER4XR is ideal for anyone looking for exceptional sound quality with just the right amount of low-end enhancement. ER•4PT, intended for sound engineers and audiophiles, comes equipped with extra accessories. ER•4PT earphones can be used with portable devices without an additional amplifier—or converted to the ER•4S response with the included P-to-S cable. Compared to the ER•4S, the ER•4PT has 10 dB greater output at high frequencies and 13 dB greater output at low frequencies. The higher sensitivity and enhanced bass of the ER•4PT have made it the most popular earphone in the series. ER•4S earphones were designed to compensate for the high frequency emphasis in all CD recordings, in order to provide accurate sound reproduction. Performing musicians often use them as in-ear monitors because the response of the ER•4S matches the response of most typical monitor loudspeakers. The high accuracy and exceptional sound isolation of the ER•4S have made these earphones popular with musicians, recording engineers and audiophiles. ER•4S earphones can be used with a headphone amplifier when using low power portable devices. ER•4B are for the binaural recording enthusiast. The ER•4B is an ideal earphone for use with material that has not been equalized for loudspeaker playback. It was developed from the ER-1 earphone that is referenced to a flat diffuse field and used primarily for speech reception research, where the goal is to produce the same frequency response at the eardrum as would be produced in the live situation. –>Accurate Earphone ReproductionFor earphones to have 100% accuracy, a recording of a live performance must produce exactly the same sound at the eardrum as the original performance.

Important: Sound quality, full bass response and noise isolation all depend on a good eartip seal in the ear canal. See a video demonstration of how to get a proper fit in the Earphone Insertion Video
Remove earphones slowly with a twisting motion to gradually break the seal. Do not pull on the cable to remove the earphones.
Shirt clip attaches to the splitter cable.
Slider is used to snug the cable under the chin to help secure the earphones.
Etymotic earphones have special filters that smooth the frequency response and prevent earwax from entering the earphones. A filter is located at the end of the earphone and is visible when the eartip is removed. If a filter becomes clogged, it should be replaced. A dirty filter will reduce earphone output. The filter should be changed if loudness decreases or the sound quality declines.
Note:Filters are not reusable.
Note: Use the tool to remove the filter.
Note: Do not use the tool to replace the filter.
Over time eartips may lose their elasticity. For best performance and retention, replace 3-flange eartips every 60-90 days. Replace foam and glider eartips frequently.

Outstanding products and 5 star service
I struggled over the ER4SR vs XR and ordered both. When I switched to balanced cabling on the SR, using a Fosi DS2, the bass became perfectly balanced. There was no need to open the XR and returned it. I have read that balanced amplifier sections are frequently superior to their same-device single-ended sections and sometimes have stronger bass. That was true for my amp. The ER4SR are the perfect upgrade for my ER4P (I broke the cable on those). While I did manage to recover the ER4P, that repair is delicate and I wanted something I can travel with, so I’m extremely happy with the ER4SR !
I have 2 pairs of over the ear headphones that are wonderful. But since I had some hearing loss in my right ear a few years ago, I stopped listening to portable music devices. Even before my hearing problem, I was eyeing Etymotic earphones. I've been traveling a lot recently and ear "buds" have not been my favorite devices especially since they have to be paired with devices (and I am a tech nut, I have many devices and three cell phones I switch from). So I wanted wired earphones again and decided to just go for it. What a pleasure! Clear sound, faithful reproduction. I can even move the ear tips to a particular angle and it's like my hearing problem is almost gone! The added bass is so smooth I don't even catch it but it might be due to my hearing condition so you must see if it suits you. I have been listening exclusively to music with these since I received them. Very well made and they came with many ear tips to choose from. I recommend trying several until you find that "right" fit.
I bought a pair of ER4XR 6 years ago because I was looking for a little more bass than the ER4S I had been using for many years. These ER4XR improved slightly on my experience with the ER4S in terms of fidelity, accuracy and clarity (the ER4S are still fantastic IEMs), but also with a little, just a little, more colour in the bass. I don't like to equalise the IEMS, the way they sound with my IFI Gryphon I don't need to look any further. You quickly get used to the way they work, and they never get tired, either in sound or placement. If you like music as it is, the ER4 family is one of the best options available
