Have the device after a long wait (Amazon atypical) get. Have it turned on connected to the test with smartphone and it ran. Turned off it and put it on the charger of my phone. Now hours later, I wanted to use the equipment for jogging and at first it went well so far. The small speakers sit miserably and press time. Okay. I thought, however, could not be optimally adjusted from the beginning of the sound, so that certain sounds are louder than others and also the hurt. Later in the evening I wanted to listen to music but could be the headset no longer turn on. Covered the battery is empty and wanted to invite, but came no sign of the current was assumed the device is still dead. I wrote to the seller and got to a link to youtube as the coupling works. But brings in the case nothing and I wrote again to watch. Until no reaction. Then turned to Amazon, and the case described with the result that I shall pocket of an address was in England and I submit in advance the package. I am really the post office and found out that it is very expensive to send to England. Wrote so pocket and demanded a Reture label. The upshot is: Amazon wrote me that the Returefall was set. Super Kundenfreunlich really. Pay nothing in which traders buy and headphones comes to the recycling center. I'm disappointed in Amazon that you offer to your customers no options where seen is the Chinese product is shipped and can no longer be claimed if defective. From because of exchange policy and warranty when the shipping costs more than buying. No thanks.
