    Great Speaker!!

    6 stars should be possible for this item. I've owned 50+ Bluetooth speakers of various brands and sizes. i got sick of mediocre sound and sound quality. i walked into bestbuy looking to get a laptop for music software and a ridiculous speaker to enjoy it on. if i want to play something way too loud and have it still sound great, then i turn this to about halfway. bass cuts through walls, there's no distortion. it's just a well designed speaker. i recently moved and tried something interesting out. throw this bad boy in the back of a box truck if you're looking for some big sound. but be warned, they will come asking to see your noise permit. great buy. nice job Sony.

    Wanted a JBL Partybox, so I got this instead

    Of course its a "portable" bluetooth speaker and not a serious home setup but its still pretty awesome and easily the best BT speaker I ever had. It has too much volume for my apartment so I have it at half volume most of the time and had it playing for ~3 hours with Ult mode 1 and battery only went down by ~10%-15% without the lights, honestly pretty good for how loud it is. Many online say the bass on this is lacking and I disagree, they havent listened to this in real life, sometimes its too much with Ult 1 and thats not to say it sounds bad because its not, everything is crisp and clear without hurting your ears like low quality speakers do. If you know you're a basshead then sure go for a JBL Partybox. Otherwise, if you like listening to many different genres especially ones with a preference for vocals like in Regional Mexican music, then this is just easily the superior pick in my opinion. I recommend this and even more if its on discount. I drove to another city and got mine Open Box for 620 and was literally brand new. Big thumbs up

    Look No Further for Your Party Music!

    I absolutely love this music tower. It delivers powerful sound with mega bass that you can truly feel. The 360° Party Sound fills the entire space evenly, making it feel like a live concert no matter where you’re standing, and the 360° Party Lights add an exciting atmosphere that instantly elevates any gathering. The bass is deep and punchy without overpowering the music, and the sound pressure stays strong even at higher volumes. With up to 25 hours of battery life, it lasts all day and night, and the carrying handle and castors make it easy to move anywhere. The karaoke and guitar inputs are a huge bonus and make it perfect for parties, family events, or casual jam sessions. This speaker is fun, loud, and versatile, a true party essential.

    Sony ULT Tower 9 short review

    The Sony Ult Tower 9 surprisingly impressed me after hearing the bass didn't go that deep but most people use it in ULT Mode 2 which is just upper bass with a brighter sound signature. With the Ult mode off this speaker still sounds pretty open with the 4 tweeters and 2 midrange drivers for a widespread but forward sound with the 12.5 inch woofer delivering enough bass to know you listen to a big speaker but not that much of a impressive speaker until you turn on ult mode 1 so whatever room you bring this speaker you will experience a strong 50Hz to punch to feel the vibrations in the air from the bass and the air thelar has enough low end extention to get that 35Hz movie theater experience while bass up to 65 Hz is still very solid. since this version does come with a battery it is very nice to roll from room to room but carrying this speaker outside sucks. Battery life is decent you can get about 3 and a half hours with the volume on 45% but I haven't preformed a real stamina test yet. It sounds a lot more open than the JBL Partybox 520 but the 520 is much better suited to be on the go and deliver much stronger low, sub bass but then again it can distort a lil while the Sony keeps its composure except for rapidly turning the volume up or down then youll here pops. So I can recommend this speaker as a large indoor party speaker with great sound and a lovely light show
