While the headphones look nice, the temples are easy to adjust and are also good at the ear, the main task of a headphone is not met. The sound is completely muffled and an insult of each ear and a turn-off. Worst who with the Sony Xperia Tablet Z2 works - to hear voice / text hardly recognizable melody. Then tested at 3 other mobile phones and PC. Voices / text more understandable still dull. As a comparison, then a simple, about 7 years old Sennheiser headset plugged into any device - anywhere a problem and to worlds better sound. Here is a popular television series is once again trying to scrap a product to take the money out of his pocket the parents with the logo. Although the price may not seem high at first glance, but once you wants to listen to music, is clear to everyone that the headphones are good for nothing.
