From the manufacturer


Etymotic Research, Inc. is an engineering-driven research, development and manufacturing company. The name 'Etymotic' (pronounced 'et-im-oh-tik') means 'true to the ear'. Innovation, education and hearing conservation are central to Etymotic's mission.

ER4XR Extended Response

The World's Most Accurate Earphones Just Got Better!

Over 30 years ago, Etymotic invented noise-isolating, in-ear earphones. Etymotic's original design, developed for auditory research and hearing testing, used balanced-armature receivers and established these speakers as the gold standard for high-definition, in-ear earphones.

  • Detachable 5 foot cable
  • High performance balanced-armature drivers
  • Sleek driver bodies with anodized finish
  • Braided cables for reduced microphonic effect

Why Etymotic?

Etymotic designs products to measure, improve and protect hearing, and enhance the listening experience of music lovers everywhere. Audio engineers, musicians and audiologists at Etymotic have generated over 100 patents issued and pending.

Why ER4XR Extended Response?

ER4XR is the earphone for music lovers and hi-fi enthusiasts who want uncompromising accuracy in the mid-range and high frequencies, but appreciate a bit of extra presence in the lower end.

The ER4XR incorporates the stringent channel matching standard used in the ER4SR and is built with precision machined, anodized and laser-etched aluminum bodies, and features user-replaceable detachable cables.

The ER4XR is ideal for anyone looking for exceptional sound quality with just the right amount of low-end enhancement.

Specifications

  • Frequency response 20Hz-16kHz
  • Channel matched to within 1dB from 100Hz-10kHz
  • 35-42 dB noise isolation
  • Impedance 45 ohms
  • Sensitivity: 98 dB SPL at 1kHz, 0.1V drive level
  • 122 dB maximum output
  • Assembled and precision matched in the United States

User Detachable Cables

To detach the cables, pull the cable connector away from the earphone body. Pull straight out-Do Not Twist.

To attach the cables, align the key tab on the cable connector with the notch in the body of the earphone. Press together until it snaps in place.

Changing the Filters

Etymotic earphones have special filters that smooth the frequency response and prevent earwax from entering the earphones. The filters are located at the end of the earphone and are visible when the eartip is removed. When a filter becomes clogged it should be replaced. Filters should be changed when output decreases or sound quality declines.

In The Box

    Product 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.

Customers also mention that the headphones are small, surprisingly compact, and fit in a cute little pouch. The drivers are smaller and weigh less than the Shures, and they stay in their ears perfectly.

    119 customers mention82 positive37 negative

    Customers are mixed about the sound quality of the headphones. Some mention that the sound is crystal clear, good in terms of sound isolation, and exceptional. The sound is slightly warmer and has a tasteful amount of bass. They also say the noise reduction is sufficient for a passive isolation type. However, some customers say that the high volume makes them lose auditory awareness of their surroundings, and the voice range is a little less forward.

    Customers are mixed about the quality of the headphones. Some mention that it's an outstanding product, while others say that it is not very forgiving of poorly mastered or poorly recorded music.

    Customers are mixed about the performance of the headphones. Some mention that they work well to talk on their phone in public without too much background, and with portable devices. They also work beautifully on metal and rock, and are very useful for traveling. However, others say that they don't work at all, the right side just stops working within a month of use, and they leak, which degrades the performance significantly, especially the bass response.

    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 Amazon. 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! 😊

    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.

    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.

    That brings me to the difference between the Etymotics and the Shures.

    5.0 out of 5 stars Un IEM incroyable !
    Reviewed in France on April 29, 2020
    Si je ne devais choisir qu'un seul IEM pour le restant de mes jours ça serait sans aucun doute le ER4XR !

    Packaging :
    Rien a redire c'est très pro, tout ce qu'on a besoin est la. Les embouts (silicone,mousse), le convertisseur jack 6.5-3.5mm, les filtres et son outils, encore des embouts. On trouve aussi le certificat de test de IEM ( avec un matching absolument parfait pour ma paire, THD très bas et sensibilité comme annoncé).

    Qualité de fabrication :
    Parfait rien a redire ils font premium, il sont super léger et très bien fabriqué.

    Confort :
    La encore un sans faute. Au début c'est une petite aventure de les insérer dans la conduit auditif (j'utilise les embouts à trois flanges de la plus grande taille) j'avais un peu peur de me faire mal en insérant trop profondément l'IEM mais il ne faut pas hésiter à insérer jusqu'au bout ce qui est spécial au début puis on s'y fait. Une fois habitué ces IEM ce révèle être extrêmement confortable, on les oubli très facilement. Après cela dépend de la morphologie de l'oreille.

    Isolation :
    C'est les IEM les plus isolant que j'ai eu l'occasion de tester, avec plus de 43 dB d'atténuation dans le haut du spectre il rivalise avec n'importe quel casque a isolation active et ça passivement. Attention cependant avec cet IEM dans la rue étant donné qu'il est extrêmement isolant cela peut être très dangereux, car on entend absolument pas les voitures.

    Son :
    J'ai eu l'occasion de tester beaucoup de casque audio et d'IEM de toutes les marques et de tout les prix allant du simple IEM distribué gratuitement a l'Orpheus. Et on a la tout ce que je cherchais dans un IEM. Un IEM très neutre, très agréable, très rapide avec leurs Armatures Équilibré, pas fatiguant et pourtant très détaillé. On a pour une fois une réponse en fréquence (20-16Khz) que je peux croire pas comme la majorité des constructeurs qui mettent simplement 20-20Khz par défaut alors que la réponse de l'IEM s'effondre a partir de 15Khz par exemple. Bref un son qui me convient parfaitement mais qui pourrait ne pas convenir à certaines personnes habituées a des basses surpuissante ( les basshead ).

    En conclusion des IEM construit comme un instrument de mesure, handmatched, avec un superbe son.
