All in all, an excellent shoe for a good price. forward highs and soft lows creates a unsettling hole in the mids. Seré concreto en el análisis pues ya hay reseñas más completas e iré a sus pros y contras:A. I hate to spend this much money on something that looks ugly to me. A word of warning that this may not work so well with higher-end headphones, only my £50 ones worked. **Those of you with hammer toes understand. Battery life was very good.
