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. ## Features - Precision German engineering ensures excellent audio clarity, so you will hear every detail of your music. - Product Note : If the size of the earbud tips does not match the size of your ear cs or the headset is not worn properly in your ears, you may not obtain the correct sound qualities or call performance.

Unless I'm missing something, it does not have remote volume control.** A: It does not have volume control per se, but it can be configured. There are +/- buttons on the part of the cord where the mike is. The default on an iphone is those buttons skip the song forward and back. In settings/control center, you can redefine these buttons to use as volume control. I suspect that android operating systems have something similar. **Q: Do these have same length left and right cables** A: Yes. The cables are the same size. **Q: Can I get an answer on exactly how long the cord is?** A: 1.2 meters that's from sennheisers website ## Customer Reviews ### ⭐⭐ ... *by B***T on 30 October 2024* ### ⭐⭐⭐⭐⭐ Nitidez *by D***A on 30 August 2019* Tengo poco con ellos y no han pasado por la prueba del tiempo, entonces no puedo hablar de esa parte.
