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.

Mit dem tiefen Sitz im Ohr kann ich mich anfreunden. Dazu allerdings nicht mit den 2-flange Aufsätzen. Ich nutze meist die großen 3-flange oder die großen gepolsterten Aufsätze. Der Klang ist für mich mit das beste, von dem, 'was ich mir leisten kann'. Sie sind recht neutral und müssen mit etwas mehr Power angetrieben werden. Bei mir ist das der Fiio BTR7 und der Khadas Tea Pro. Beide meist als DAC über USB-C am Android Phone angeschlossen. Als Musikdienst habe ich vornehmlich TIDAL im Einsatz. Der Klang ist 'flach', im positiven Sinne, aber unheimlich detailreich. Meine bisherigen Favoriten bei InEars sind die Tangzu Wu Zetian und Shanling MG100, wobei ich die MG100 angenehmer zu tragen finde. Die ER4 sind, wenn sie denn mal richtig und tief im Ohr sitzen klanglich sogar noch besser und der von vielen bemängelte Bass ist dann auch da. Ich würde mir dieses Modell auch wieder kaufen! Leider war das Kabel bei meiner Lieferung defekt und hatte DropOuts auf dem linken Kanal, wenn ich den Kopf bewegt habe. Also habe ich mich an den Support von Etymotic gewendet und ohne weitere Nachfrage ein neues Kabel zugeschickt bekommen. Jetzt kann ich die InEars richtig geniessen.

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.

Excelente producto, desde el empaque y los accesorios se nota la atención al detalle, la caja y bolsa para guardarlos se ven y se sienten de lujo. El sonido de los audífonos es excelente. Son extremadamente claros, es decir, la definición entre un sonido y otro es muy, muy buena. Se vuelve mucho más sencillo distinguir pequeños detalles del sonido sin que se sienta artificial o con agudos exagerados como se puede percibir con otros audífonos y altavoces. El sonido en ningún momento se siente "cansado", aún con grabaciones que están muy saturadas y con poco rango dinámico (diferencia entre sonidos con poco volumen y mucho volumen). Bajos profundos y definidos, no exagerados. Posiblemente no sean suficientes para quien esté buscando un bajo resaltado sobre otras frecuencias. El escenario sonoro no es tan amplio como otros audífonos, pero los otros puntos fuertes hacen que no se extrañe y ni siquiera se note mucho. En general me parece que son excelentes audífonos, suenan muy bien conectados directamente al teléfono o a la PC pero realmente se les puede sacar su mayor provecho utilizando un buen DAC y amplificador de audífonos. Lo negativo: la tecnología de los audífonos requiere que se introduzcan de manera profunda en el canal auditivo y no a todo mundo les acomodará utilizarlos, pero si eliges las "gomitas" o "espumas" adecuadas no son molestos. Esto también provoca que si produces demasiado cerumen necesites cambiar los filtros de los audífonos con mayor frecuencia. En general excelentes audífonos, excelente sonido, excelentes accesorios, la comodidad no es excelente y dependerá de cada persona pero son altamente recomendables.
