Etymotic Research Er4XR Extended Response Precision Matched In-Ear Earphones (Detachable Balanced Armature Drivers, Noise Isolating, High Fidelity, World Leader Response Accuracy), Black, Standard

I purchased it when it was a 450dhs sale. I mean this earphone is well-known for its superb sound quality. Although it is old, it still outperforms other IEMs in the market. Highly recommended.

The Etymotic ER4XR are my first dive into the world of high-end IEMs and I consider myself to be very lucky as I feel that I have reached the endgame. I've dabbled into midrange IEMs as I've always preferred these over other forms of headphones. Another testament of these headphones is the packaging and the amount of accessories that come with it. The fit of these takes some getting used to but once you do, they become extremely comfortable to the point that you forget you have them on. The audio quality is incredible and the imaging is some of the best I have ever heard. The XR has more bass than the regular ER4s however these IEMs are DEFINITELY NOT FOR bassheads. The bass however is very clean and fast and it never muddles the sound. Also, one thing to keep in mind is that once these bad boys are placed correctly in your ears; the isolation is just mind blowing. This is a completely different ballpark to ANC. It basically creates a vacuum chamber in your ears where even playing music at 30% level will cut out almost everything. I wore these on the plane and at 40% volume from a DAC-powered phone, I could NOT hear the plane at all. Just be wary that the fit is not for everyone, these IEMs will physically violate your ears for the first 10 days of you wearing them. Start slow and slowly your ears will adapt to the feeling.

As a professional sound engineer, these are the only in ears that I can mix confidently with, knowing that my mix will playback nicely on anything. I started it with the SR 4 then moved to the XR 4. The SR are perfectly fine but the XR has a slight boost in the bass that resembles a studio subwoofer. These headphones are super flat and truthful, they tell it as it is, no gimmicks here. I initially ordered the $1000 sure Se 846 gen 2 monitors, to keep it short, don’t follow the hype and the YouTube reviews……these are the only in ear monitors that come close to my trusty Genelec monitors, cold, harsh, flat and truthful, no make up here, no eq, no boss or gimmicks, no multi drivers that are full of phase issues and frequency dips, no disillusioned Audiophiles who imagine frequencies. This is the best in the business period. If you want the best hyped sound then get yourself a Beats headphones and enjoy your workout!

Wonderful quality! Best sounding IEM ever listen to!

O produto em geral é muito bom. Todavia, as espumas dos fones que acompanham estavam amassadas e duras quando abri. Deixei elas aerando para ver se recuperavam a forma... mas elas continuavam deformadas. Testei um par, mas a dureza da espuma machucou o meu ouvido e a espuma simplesmente se soltou do tubo interno quando fui substituir pelas flanges de silicone. O certificado mostra que o produto é de 2019/2020, sendo vendido em meados de 2024... parece que envelheceu na caixa e o Amazon está desovando o produto velho no mercado brasileiro. Fiquei constrangido e decepcionado.

I got this etymotic at a special discount which made it all the worthwhile. This earphone is all that reviews described and promised, full range detailed sound with just enough base to give it a good support and brings life and imagery to the sound stage. Music especially classical music comes to life in a very real way. This sounds very close to my sound system and I am awestruck. It's indeed a great bargain.

Als ich im Sommer von 1986, auf dem Bau zu arbeiten begann, gab es noch nicht so viel Aufhebens wegen Gehörschutz, dadurch wurden meine Ohren a bisserl beleidigt, ich brauche seitdem gute Kopfhörer, und die sind teuer, ok! Seit ich diese Kopfhörer benutze, ist das Rauschen ( Pfeifen ) in meinen Ohren nicht mehr so stark , und ich kann es nicht anders beschreiben, die ER4XR geben mir sehr wohl bekannt, wenn die Lautstärke zu hoch eingestellt ist, der bis dahin geschmeidige Klang wird schrill und ich kann wirklich schnell darauf reagieren und ein wenig leiser drehen. Ich liebe diese Präzision, diese Inear sind wie für mich gemacht! Ich habe sie am ersten Tag mit den original aufgezogenen Silikon „Stöpsln“ betrieben, der Halt und der Klang im Ohr sind spitze. Hab jetzt die Foam Eartip aufgezogen, der Halt und der Klang sind fantastisch!

These are very impressive earphones. Bought in June 2025 for Amazon sale price of £193. I have not heard as accurate, exciting, detailed sound from any portable source before (in ear or over ear). They reveal everything about the music. I think they have enough bass (the ‘XR’ bit seems to deliver). The isolation is good, not as good as active noise cancellation but with ANC you get strange artefacts and a kind of ‘wash’ over the sound. With these, you just hear less of the world because the fit is so snug. On the fit. If you read some reviews you will probably be a bit scared (I was). In reality, they don’t go extremely deep. A little deeper than usual earphones but not uncomfortable. Takes a small amount of getting used to. Because music sounds so good, I kept putting them back in! So they can’t feel that bad. Soundstage is narrow because of the fit. But you can hear everything in its proper place in the stereo field. I’d 100% recommend. If money was no object, then they are still very much worth it at full price. They have lots of excellent box candy too, including a graph showing how well matched the two individual earphones are. Bravo.

Every instrument, vocal is separated. Great to listen to tracks to observe minute details. Using with a Dragonfly Cobalt DAC and have been greatly impressed. Fit to the ear canal is right and as a result gives passive noise cancellation. Recommended for music enthusiasts. Bass not the most punchiest but quite acceptable.
