Review: Nitidez - 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.
Review: bis jetzt der Beste - Zu Hause liegen sie herum, die Ohrstöpsel, ein paarmal verwendet und dann frustriert verworfen. Der Sennheiser CX 300S ist eine wohltuende Ausnahme. Klar im Sound, nicht Bass lastig. Der Sound kommt an, wie er soll, nämlich TRUE. Die Stöpsel rutschen leicht aus dem Ohr heraus - das ist der einzige Schwachpunkt. Empfehlenswert !

### ⭐⭐⭐⭐⭐ Bons écouteurs intra auriculaire
*by C***. on 21 December 2024*

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.
