Review: Sound quality is outstanding - This is a superior product. By using the XE Equalizer app with this, the unit produces crisp clear mid range, high notes with a rumbling bass that's pure and pleasant. Within 30% of the volume, the music is soft, rich, powerful bass that's absolute bliss to listen to. By having water and dust proof rating, the unit can be cleaned with spray water and can be used on the balcony with no worries of a rain spray. Buy with no doubts, it is full value for money. Enjoy
Review: Decent speaker...loving it - It's a decent speaker but over hyped.... the reason i bought this speaker because of it says that it has a low frequency of 20Hz which i found is not true.... sounds great up to 40% then if you increase volume the sound shift mostly on mid and higher frequency and it's loud but no bass at all even with EQ settings you can enhance bass but still not effective on higher volume... i definitely liked this sound better than jbl boombox .... i am reviewing it again after listening of my six months experience that it's a wonderful speaker and i realized the most fun part is begin with when you put your speaker on ultfied1 mode then you do eq settings with your phone eq not with sony eq app because to use sony app eq you need to change mode in to custom which is not good but trust me once you have set the phone eq on ultfield1 mode this is gonna be whole different level of experience... try it and that's the only reason i am giving it from 3star to 5 star after using my phone eq settings
