    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!!!

    5.0 out of 5 stars I tried Bose
    Reviewed in the United States on February 11, 2019
    Verified Purchase
    For the money this unit has the best all round sound reproduction
    Not heavy bass, not a tinny sound on the highs - best all round sound
    I had the Bose minilink? Nice, well made but not the substance to create sufficient bass.

    I also had the XB40 - too much sound - its easy to reproduce loudness but very difficult to provide a well balanced sound-just enough base and just enough highs its called "Balance"

    Feature that really set's it off is the surround sound and RGB LEDs - lights are nice but you do not know they are there after a while

    Great sound with no sacrifice on sound because of other features which by the way are prettty significant to inlude IP rating-yes you can drop in pool and it wil survive, if you want to step up the volume for outdoor backyard party use
    buy 2 that allows true stereo as they are able to link to eachother wirelessly as one unit - as it will will all Sony SRS series of Speakers.
    Rechargeable battery life is accurate as stated
    I cant say you will be thrilled but I can say I am - Sound is such a personal experience

    5.0 out of 5 stars Awesome sound + fun lights
    Reviewed in the United States on November 2, 2018

    This is my second one, as I gave the first to my son. I got it to connect to my new laptop for better sound. I tried it out today during a power outage when I couldn't listen to my Sirius XM boombox. I connected an external dvd drive and put in a Bobby Rush CD and was blown away by the great sound. Once the power came back on, I tried connecting it via bluetooth to the Sirius radio but no luck; not sure why. May have to fiddle with something to get it to work. The only thing that could make this better is a remote to adjust or mute the sound. This would be great for watching movies on your laptop, as the sound is fantastic. I also got a hard case that fits perfectly (Esimen 2018 Design Hard Case for Sony SRS-XB31 XB30 Bluetooth Speaker Carry Bag Protective Box). I highly recommend!

    5.0 out of 5 stars Bass heavy party speaker
    Reviewed in the United States on November 21, 2018
    Verified Purchase
    Do you like your bass deep? This speaker is for you. Do you enjoy customizable light shows? This speaker does that pretty well. Different approach from some of the other speakers out there, and once the lights are off you wouldn't even know it has a "Rave" light mode. I am using the XB-31, I also picked up the XB-41 for someone else and they both sound great. The latter is marginally louder and works with the second app, Fiestable, whereas the first only works with Sony's music app. The Wireless Party Chain could use some work, wasn't able to get the two to sync up and play together. For its main purpose, the XB-31 is the right size, waterproof, and LOUD. I am going to enjoy this thing for years - and if I don't I'll update the review to reflect that reality.

    5.0 out of 5 stars Awesome speaker with great sound.
    Reviewed in Canada on January 8, 2020

    I've never been disappointed with a Sony speaker yet, and this is no different. Great looking speaker with amazing sound. The fabric covering is really nice to have. Haven't had to test it's water resistance fully, but have had a few splashes on it here and there, and the water just wipes off.

    It's got a good heavy feel to it and the build feels expensive. Syncing was super easy, although it did take a bit to link it to my other Sony speaker, but once I did I had some great stereo sound happening.

    For the price, I am glad I bought this older model and didn't spend more on the newer one. Totally happy with it!

     Es excelente, hasta ahora ha funcionado bien, cabe aclarar que la batería durará a lo mucho unas 5 horas con volumen máximo y luces encendidas. Les dejo una pequeña muestra del audio aunque claro que no suena igual en persona que grabado del celular, pero sirve para darse una idea. Respecto a la potencia del volumen es suficiente para una habitación de mediana a grande e incluso suficiente para una pequeña fiesta.

    Llevo cerca de 1 año utilizando este producto y en definitiva no se ha deteriorado, su calidad de sonido sigue siendo igual de buena que al comenzar a utilizarlo. Su sonido es potente y no tiene distorsión al utilizar a su mmáximo volumen. Entrega en tiempo, de calidad y excelente. Le daría 5 estrellas, pero su único inconveniente es la batería, dura muy poco y tarda demasiado en cargarse completamente.
