    The sound quality and battery life are amazing in this speaker. I was torn between the JBL Party Box. I ultimately ended up choosing this because of the battery life. Not disappointed in the least bit with my decision. Would buy again.

    Best Party Speaker I Have Ever Heard

    Tech Insider Network Member
    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Sony has released their new ULT series speakers The ULT Tower 9 is the biggest and baddest of the bunch. The box comes with the speaker, AC power cable, optical cable, and some paperwork. The speaker comes with a manufacturer's 1-year warranty. Disclaimer 1: This speaker comes in the 9 and the 9AC series. I'm reviewing the 9 series which includes a built-in battery. Disclaimer 2: I used 2 phones to connect to the speaker simultaneously - a Samsung S24 Ultra and a Samsung S23+ PROS: ----------- * HEAVY-DUTY. This thing weighs around 70-75 lbs but has wheels for easy transport. It's a solid unit. Nothing feels cheap about it. The 2 wheels are independent of each other when they turn. * THE SOUND. THE SOUND. THE SOUND. Yes, I said it 3 times because it sounds that good. The bass options and 10-EQ graphic equalizer put this party speaker at the next level. The ULT button (or change the bass on the app) switches between 3 modes and OFF. I don't know why anyone would choose OFF, but it's there nonetheless. You have a deep-bass option, a punchy bass option, and a custom EQ option which is set in the app. The ULT letters on the button light up when light mode is ON. * 360-degree sound. The bass driver aims frontward; however, the port in the bottom spreads out in 360. The mid-range drivers also face front only. 2 tweeters face front while 2 more tweeters face semi-backwards as they are angled at the corners on back. * The battery will last you nearly all day long if you have it hitting hard. At medium levels, Sony claims 25 hour playback time when on battery by itself. If plugged in, the party never stops. * The lights are placed underneath the 4 sides of the handles and in the bottom where the bass port is located. There are multiple options to pick from in the app but you can pick a single color or multiple colors via the touch-buttons on top of the unit. The lights also will match up to the beat of the music. In addition, they can simply be turned OFF as well if lights are not needed (and to extend play time since less battery is used). * Officially it can connect to up to 100 speakers... I believe they have to be Sony though... and certain capable ones. I'm not sure when 100 will be needed or even 20, but they state it can be done. * You have the ability to connect up to 2 wired mics or an electric guitar to the speaker using 1/4" plugs. Sony has a great option with the ULT-MIC which features a plug-in wireless adapter which connects to 2 wireless mics (which have to be charged up). The speaker has 2 punch-out slots that will hold each mic on either side of the top of the speaker. So it can hold both mics when not in use. If mics aren't needed, those mic holders can be clicked into the body of the speaker (hidden). * The mic/guitar ports stay hidden away if not used under a magnetized rubber boot. When opened all the way, the magnetic rubber cap snaps in place to the top of the speaker so it doesn't dangle or look weird. This was good attention to detail by Sony. * Connectivity for 1 Bluetooth (BT) device is simple. Use the Sony SoundConnect app to make use of all the great party options with the speaker. * In using my Samsung S24 Ultra/S23+, that phone has the option to connect to 2 different BT speakers at the same time even with different manufacturers. The Sony ULT9 was able to be paired alongside a Nyne Rebel speaker at the same time. There was only a hint of reverb where the sound wasn't 100% in-line, but it was to a degree that sounded pretty cool... we're talking less than 0.1 seconds difference if at all. You can also control the volume of each speaker independent of each other (See picture) * The speaker comes with ample ways to connect including BT, 3.5mm, and optical which are all accessible in the rubber door panel on the back. This is great for simply making any TV sound great anywhere. This would be great for tailgating at football games too.... music/TV - it can handle it all with plenty of battery power for the day. * Includes a regular USB charging port on the back for charging phones and other small rechargeable items. With the size of this battery, there's plenty for a lot of extra device charging. CONS: ----------- * There a big problem with switching between the sound types in the DJ Control section on the app. There are 4 settings... (1) DJ off (2) Isolator (3) Flanger and (4) Custom EQ. When listening to a song, if you switch between Isolator and Flanger or vice versa and tap the circle to pick how you want it to sound, the volume goes nearly off all the way while the setting changes... it's actually quite bad. A software update to the unit itself should be able to fix this... but it's extremely annoying not to be able to switch between them seamlessly without a break of sound being heard (or not heard). Sony, please fix this. * The speaker would not connect to the Sony SoundConnect app EXCEPT when I provided the QR code that was in the material provided in the box. Let's say I lose that piece of paper that has the QR code on it - how am I supposed to connect the speaker then? I was unable to do so. This will hopefully be corrected in another SoundConnect app update. * There were some issues switching between phones with the app open on both. One time, it wouldn't switch at all; however, music was playing on phone 2 while phone 1 had the app actually open (as if it was connected). I disconnected both and reconnected and eventually they synced up. There were some hiccups there in the app with connection to 2 devices, but hopefully those bugs will get ironed out in future app updates. Note that music can only be played from one device at a time when connected - you CAN'T play 2 different songs, 1 from each device, at the same time. It's not like dual mics where you can have 2 singers singing at the same time. Once the 2nd device hits PLAY, the current song playing will cease, and the new song will start. * The wheels are great, but I wish they had some way to extend a handle out of the back of the speaker so taller people could pull it a bit easier (like luggage has a retractable handle). Not having that little extra length can make it a little difficult to walk and pull it in some instances due to height. * I'm not a fan of the "Battery fully charged" announcement when the speaker is powered on. I'd like to simply see a battery % on the app so it doesn't seem so cheesy when I turn on the speaker. Perhaps make that an option to toggle. I did not see that option. If it's available, Sony, please comment and let me know. Maybe a new feature in a future firmware update. OTHER OBSERVATIONS: ----------- * The top is "splash-proof" but not waterproof. It shouldn't be played in the rain. * The SONY emblem on the top/front of the unit is made of material that reflects light like a prism instead of being solid white. This is a nice touch. * With the ability to have 2 mics or a guitar plugged in, you can do karaoke; however, I do not have a mic or guitar, so I have not used these functions yet. There are also karaoke functions in the app and controls on top of the speaker that can be used, but I was unable to use those at this time. A great use besides karaoke would be to take on travel/select youth baseball games where players can come to the plate and have a walk-up song and the parents can announce who is up to bat (or new pitcher)... fun stuff like that. You would be the talk of the team if you brought this beast to a game. * The speaker itself did take a firmware update after a few minutes it was powered up. It took about 5 minutes to upgrade. No issues. * There are some other features in the app that might be useful to some people including a sound field optimization function (it adjusts sound/frequencies based on surroundings), TV sound booster, Battery care, auto standby, Notification & Voice guide (which I have OFF but it still tells me the battery power when powered ON), and the Stamina function. CONCLUSION: ===================== This speaker is something you'd hear at a frat house - LOUD AND PROUD. It does not disappoint AT ALL except for the app glitches which Sony should be able to resolve with future app and/or firmware updates. The sound is simply out of this world for a speaker this size. Throw in the versatility, and you have an "everything" and "everywhere" speaker with enough battery to last the whole day pretty much. I'm seriously impressed. My main regret here is that this speaker wasn't available 10 years ago when my kid started playing baseball. The price point is a bit high; however, you will use this speaker for many years and enjoy listening to music with it. The sound is just incredible. Great job, Sony.
