So loud
||Posted . Owned for 4 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.“This speaker works well for everyday use. The sound is clear and loud enough for small spaces, though the bass could be a bit stronger. Setup was quick and easy, and the battery life is decent. It’s not the most premium option out there, but for the price, it does the job.”

Posted .Thank you for your review, VICTORIAG!
We’re glad to hear the ULT TOWER 9 was easy to set up and delivers the clarity you're looking for. Since you mentioned wanting a bit more punch, definitely try toggling the ULT button! It’s designed to unlock two different levels of deep, resonant bass that should really fill out the sound.
Thanks for choosing Sony for your home audio!

Nice bump, nice upgrade
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is a upgrade to the 900 model. When i tell you that they could have put this in its own category. The sound is soooo much better than the 900. The bass is unbelievable. Very nice highs and lows. This one speaker sounds better than the 2 900s that i got. You will not be disappointed if you decide to purchase this unit. With that said, you also have a choice,. You can get the ac only or you can get the one that has battery and ac. With the battery version, you get up to 25hrs of play. Will you really get 25hrs? I dint know, but i do know that you throw a party and it will last more than 5hrs on a charge. It also have a quick charge so if it does die, you would only be down for 5min at the most and you will be right back to the powerful sounds of this sony beast. Highly recommended.

Wowzerz!!!!
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Wow! You xan actually feel the bass in uour chest, the sound isnt distorded when you turn it up, i have only turned it up a little over half way, if you know how to set your equalizer on your iphone in the music app and the equalizer from the app, the battery last for days, i listened to it for 18 hrs straight with no problem, just have the stamina setting on and you will be amazed, the price for the speaker is worth every cent, theres no comparison to the sound this speaker puts out! Impressive! All tbe way around, And dont forget to face it towards the corner of the room you’re playing it at, and Wow! Is what you’ll say! Guaranteed! Hopefully this review makes someones decision easier to make.

Massive Sound, Deep Bass & Ultimate Party Speaker
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The Sony ULT Tower 9 is one of the most impressive party speakers I have used. From the moment I turned it on, the powerful bass and room-filling sound stood out. Sony's ULT Bass mode delivers deep, punchy low frequencies that make music feel energetic and immersive, whether you're listening to hip-hop, EDM, or pop. The 360° Party Sound feature helps spread audio evenly throughout the room, ensuring everyone enjoys the same great experience.

Great but not perfect
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Very capable speaker. We got 2 for use in stereo pair outside with the projector and for parties around the pool. There are issues with the app sometimes not allowing me to connect two together. That would give me 4 stars but the speakers pair buttons work just fine so it’s no issue. The speaker resets everything to defaultbsonifnyou need less bass and set the bass eq lower through the app you will have to do it every time. Will update when we ensure the optical out in the projector works with the speakers being in stereo pair mode No other speaker has optical out and we were sold on the 25 hour battery functions

Sony ULT TOWER 9: The Ultimate Audio Powerhouse
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The Sony ULT TOWER 9 is an absolute beast that has completely transformed my home setup. Whether I'm hosting a party or just relaxing, this speaker delivers in every category. Massive Sound: The audio is crisp, and the ULT button provides a deep, chest-thumping bass that fills the entire room. Cinematic TV Audio: I’ve hooked it up to my TV, and the TV Sound Booster adds a rich, theater-like layer to movies and sports that built-in speakers just can't match. Karaoke King: This is my go-to for karaoke nights. With dual mic/guitar inputs, echo controls, and 360-degree lights that sync to my voice, it feels like a professional setup. Final Verdict: From music to movies to late-night karaoke, the ULT TOWER 9 is the best investment I’ve made for my home entertainment.

Clean, smooth, and best money spent.
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.So far so great! The sound is clean. The bass in the ult 1 & ult 2 id more than enough. The battery life is very accurate; but all depends on how loud you listen. To be honest, I can’t turn it more than 30% because it’s loud and clear enough for me. We’ve been singing karaoke out from the thing for 2 plus hours every now and then. I like it a lot and glad didn’t go with the 520 Partybox; too much bass.

Best Portable Speaker for the Price
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.[Employee of bestbuy] Like what the title say. You can't really get better sound quality for the price. I've had JBL, bose and other home theater equipment for comparison and the Sony one is a league above in terms of music quality and impact. It gives you the feel of a much higher quality dedicated tower speakers with amplifiers. Bass is surprising for its size. Added bonus for mic inputs and optical.
