Following recession I would like to leave but to the headphones: In general, make the headset a good impression, they sit very well in the ear (keep jogging without problems). The Bluetooth pairing went without problems. Now the downside: battery life is not really the hit, after 3 hours of sound headphones bleated already and wanted to be like-the have juice. Here regular top unumgehbar. Far worse, I find the sound. Bass: None .... it is hardly a present, rather something dumpfiges can be heard, but only when you press the headset fixed with your index fingers into the ear and these firmly-holding case. The settings from the EQ on Smartphone brought no improvement. The advantage for me is really just the "Wireless" option between headphones smartphone when Jog gene, music lovers and connoisseurs take best more money into their own hands. I would not buy these headphones.
