Tengo poco con ellos y no han pasado por la prueba del tiempo, entonces no puedo hablar de esa parte. En cuanto a audio, suenan muy claro, reproducen todos los sonidos con nitidez, le falta un poco de cuerpo/punch al bajo pero siguen reproduciendo correctamente esos sonidos. Se compartan bien en diferentes géneros, a diferencia de otros audífonos que priorizan bajos sobre otros elementos y terminan por ser "especializados" para música electrónica básica, descuidando la experiencia de escuchar otro tipo de música. En cuanto a relación calidad-precio, los compré por la marca, no tengo suficientes comparativas con audífonos de la misma gama para hablar de este factor, pero están bonitos y tienen mejor feel que otros más baratos. Los recomiendo aunque podría haber mejores opciones, sólo que no las conozco.

Bonjour, J'ai acheté ces écouteurs Sennheiser CX 300S pour une écoute filaire donc et j'en suis pleinnement satisfait : bonne qualité d'écoute, attention à bien choisir la bonne taille d'embouts silicone et de bien enfoncer l'embout dans l'oreille : sinon mauvaise qualité de son et pas bien isolé des bruits extérieurs.

I have been trying for ages to find a replacement for my trusty Sony MDR-XB55AP earbuds which appear to have been discontinued. I don't do bluetooth or wireless when commuting. Unfortunately, it is becoming harder to find name brand earbuds these days. I do not want to purchase random earbuds from an overseas company I am not familiar with. I remembered owning these Sennheisers many years ago and was happy to find them still available on Amazon (albeit in white, I would have preferred black). They sound very similar to the Sonys but actually have better (read: more) bass. I listen to a lot of Dub Techno and Ambient on the train so need some "oomph" in the lower registers. In terms of sound isolating they seem similar to the Sonys. Of course they are not as isolating as wireless ANC earbuds but they are pretty good for wired earbuds. In terms of durability I do wonder if they will last as long as the Sonys which seemed nearly bulletproof but I will take my chances since it was so hard to find replacements.

Sonido de calidad. Se ajustan un poco mal pero el sonido es bueno. Además no sé enredan y son torteros.
