Performance wise, they offer impressive audio reproduction and deliver a well balanced sound across multiple genres. Although, their out-of-the-box sound profile may not be to everyone's liking. Luckily, that's where the excellent Sony Headphone connect app comes into play as it gives you access to a graphic EQ, so you can customize the sound to better suit your preferences.
Battery life is decent for a headphone of this style, with 10 hours per charge. A recharge takes a snappy 1.5 hours, and just 10 minutes of charge gets you 80 minutes worth of listening time.
