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 desertcart está desovando o produto velho no mercado brasileiro. Fiquei constrangido e decepcionado.

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. ## Frequently Bought Together - Etymotic ER4XR Extended Response Earphone - Etymotic ER Series 2.5mm Balanced Cable, Black - Etymotic Research Tuning Kit for ER Series Earphone with 5 Different Filters (ER-DAMPER5PACK) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/180707508-research-er4xr-extended-range-in-ear-monitors](https://www.desertcart.com.ar/products/180707508-research-er4xr-extended-range-in-ear-monitors) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-24*
