Buy headphones just before Christmas in 2013, after a few weeks while losing weight has fallen apart, the answer. Complains and get another. In August 2014. excessively frequent use defective again with cable break. Seller Online2013 refused even after referring to and send the warranty table by Sony a warranty replacement and refers to the legal guarantee of 6 months on headphones. Furthermore, the part Online2013 during the correspondence a battery from the headset, although clearly stands in my request the headphones and it was a complaint on Amazon and therefore bound items. For some time no further reaction on telephone contact attempt email cover letter and other experiments on the Amazon complaint. Unfortunately Sony Support refers in small articles only to the dealer and let the customers down In retrospect, striking: Under the item is "Samrick" as a manufacturer, the product description is but of a "genuine Sony / Sony Ericsson Stereo Headset" written ... Worst possible rating due to the extremely poor customer service, not compliance with the guarantee promise and a two-time product defect despite careful handling and a lousy Sony support.
