    Customers like the sound quality of the speakers. For example, they mention the sound is awesome, loud, and clear. The bass is amazing, and you can hear every sound in songs. The speaker is nice, and the lights add a little flair to the awesome bass it has. That said, some say the sound should be a bit louder, and that it's never distorted or hollow sounding.

    My vote for favorite mid sized speaker of 2018!!!

    My vote for favorite mid sized speaker of 2018!!!
    Heck yea worth every preorder penny!!! Love this little dude like I love all of my JBL's!!! This thing is epic it's literally like A mid sized all-in-one speaker! Has always been curious About buying one of Sony's speakers just to give it a shot but last year's models styling was just not my taste! But when I 1st laid eyes On this on CES video on YouTube It caught my Eyes, I said this is it this is going to be my 1st Sony speaker! Man am I glad I ordered this it stole first place for my favorite mid sized Bluetooth speaker but JBL charge 3 is still on its tail in second place. Referring back to the statement all-in-one having a light show being a portable battery bank as well As the durability In really good stereo sound with the nicely spaced apart drivers! The speaker is described by Sony is a fun speaker and they are right in the dark with the lights flashing it's really cool and also what they mean by phone they are probably aiming at in audience that likes party music R&B hip hop and EDM trap, It please them all like they're supposed to be heard especially in the live sound mode which Definitely seems tailored to these specific gen' Definitely seems tailored to these specific Genre's. The app works well with it for changing the lights and music settings works A-OK on my S8 plus! Awesome large room filling sound while managing to keep bass present is excellent for a speaker this size! I thought I would have to wait for JBL charge 4 but nope this took the spot at least for now!Point is if u like lively party music or even something chill this is one of the best stylish/good sounding options out there! U cant go wrong with this purchase!!!
