Hello Liras. If you google, you'll see that even cheap buds have this technology, but I'm not 100% sure*... I am very happy with mine. Rich bass, sit firmly in the ear and the only thing that bothers me a bit is the noise cancelling when I talk to someone. Otherwise I would recommend Super Buds, try them out, if you don't like them you can return them, it's also a great thing from Gala./Gigi. Greetings Edo
(*It is one of the first Bluetooth codecs to promise lossless CD quality of 44kHz. Reminder: The basic aptX codec has a maximum data rate of 352 kbit/s.)

P.S. I find it a pity that Gala./Digi. saves on good showroom. In Zurich there are only a few devices on display...
