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
Review: SONIC RESONANCE - I heard this model a few months ago at a SONY showroom in MALAYSIA. The first thing I noticed was the extraordinary sound that emanated from it. Crystal clear wide spectrum vocals with superb clarity & bass. I managed to pick this up at desertcart prime day sale for a great price much lower than what I saw in Malaysia & what was initially advertised in desertcart. Initial reaction is I'm very happy & look forward to an extended use. The speaker is built like a tank meant to withstand nature. Extremely easy to use after some initial charging. The only speaker in competition to this would be the Marshall Tufton which is slightly more expensive than the SONY.
