given for a birthday. To call this product good does not turn the tongue. ordinary, at best. unfortunately, I got a model with a factory defect - there is a quiet crackle in the left speaker, regardless of the volume set. The headphones themselves are pretty quiet. the sound of the "younger brother" of this model, 450BT, is much better and louder. it connects to the iPhone instantly, but almost never connects to the laptop (Macbook Air). there are also problems connecting to other devices. The battery holds for a very long time, it even seemed that it was more than the declared 20 hours. but they are sitting not to say that it is convenient - rather quickly you begin to feel pressure on your head. Conclusion: for their money, perhaps, and norms, but for those who stare at them, I would definitely advise you to add a little and buy something of better quality, for example, Sennheiser HD 4.40
