Since now more than three years, the headphones are now regularly in use. Several hours a week for music and radio plays. Never before has the battery made limp, even after several hours use. Throughout the house there is impeccable reception, even in the garden without any problem. Even after extended wearing pressed and pinches nothing that headphones are really comfortable.
Conclusion: class audio quality, longer battery and even after more than three years in top form. Would I buy it again. Anytime.
