After briefly listened store I bought the 300, and then at home I was quickly won over by the sound quality, so that two days after I sold it to a friend to take the 500. I have not been disappointed: a more airy, more powerful and with more bass. Beyond the fact that it is a beautiful product, that the NFC connection is convenient and works fine, what matters is the sound. It has an impressive definition with the Bluetooth and apt-x, with a good drive on your smartphone, you'll almost never do micro-cuts or other artifacts. Nothing to say, across the spectrum. One loses power battery relative to the industry, but you do not lose at low frequencies. But even battery is widely powerful enough for a room. A beautiful object to a not unreasonable price for its size and compared to other brands.
