Etymotic Research ER4XR Extended Range In-Ear Monitors

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.

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.
