    Superb
    First class sound system everything you would expect from a Sony product

    Amazing bass, can feel slightly tinny at tines
    Overall this is genuinely an amazing speaker. I did have to change the sound settings quite a bit to make it sound nice, but once that had been done it's very pleasant to listen to. One of the drawbacks is once it gets to a certain volume level it can sometimes be slightly tinny, and have too high pitch sounds coming out, but as long as it's not too loud, it's great!! Personally I love my bass, and this excels in that department, although I had to set it to "Live sound", Bass +10Db, Middle +8Db and Treble +6Db. This was it greatly increases the quality of the music. As far as I'm concerned the "Extra bass" function is useless, as it doesn't really increase the bass at all and it just muffled the sound. Having said that though once you change the sound settings in the media control centre app it is a very nice speaker.
