      Hi MohamedS,

      Thank you for sharing your experience with the ULT TOWER 9. We're excited to hear it's a great fit for your smaller parties! We certainly understand that for larger gatherings, more power is needed. That's exactly why the Stereo Pair feature is included—linking two ULT TOWER 9 speakers wirelessly provides double the volume and an even richer soundstage, which sounds like it would be perfect for your bigger events. Thanks again for your review and for considering Sony products!

      Best regards,

    I purchased this speaker with excellent open box. I was disappointed that the optical cable was missing. Spent more than 3 hours with customer service and they failed to adjust the pricing.

      Hi Hh25,

      Thanks for reaching out and sharing your experience. We're truly sorry to hear about the trouble you've had with your open-box ULT TOWER 9 speaker and the frustration of spending so much time with customer service without a resolution.

      Since the speaker was bought as an open box item, we don't have direct control over the inventory or condition of the product, however if you have any questions about the features or functionality of the ULT TOWER 9 itself, please don't hesitate to ask to our dedicated Sony Support at https://us.esupport.sony.com/support/s/support-contact?language=en_US

      Thanks for choosing Sony!

      Sincerely,

    Not a Sony or JBL guy just wanted something for my garage and while it has bass, its too much as it takes over the mids and highs. Went with (2) 120's nice tight bass and mids and highs conform well.

      Hi MichaelR,

      Thank you for sharing your feedback. We appreciate you giving the ULT TOWER 9 a try for your garage setup.

      If you still have the speaker, we would like to remind you that you can customize the sound profile using the Sony | Sound Connect app. The app features a full Equalizer (EQ) that allows you to manually adjust the bass levels and boost the mids and highs to achieve the balanced sound you are looking for.

      Thank you for considering Sony!

      Regards,
      Dominick Sony_US

    Let me begin by saying I have previously reviewed Bluetooth speakers from Sony the past 2 years. Last years ULT Tower 10 and the previous generation SRS-XV800. The ULT 9 is the perfect combination of everything I like about each of those two models. The look and familiarity makes it easy to just open the Music Center app, connect right up and load your favorite music and you are off and running. There is a new app which took me a second or two to figure out but I ended up liking more than the previous app. Great small upgrade here. Just like before, it has the abilities to add wireless mics, plug in a guitar or even become the sound for your TV. All work great and function perfectly. What I feel has improved is the ULT settings. They are not a drastic change to the sound but more solidifying and full like adding a 3rd party sound amp app. Using just the Sony app, I liked the sound of ULT 2 giving a nice full and clear sound and this speaker gets loud, just like its big brother. Where this speaker is better is it is fully wireless and has a long lasting battery. So far, I am on day 3 of not charging using it about 3 hours a day. The lights are the same but seem to be brighter and flash in better sequence with the music and the settings are easily controlled from the app. Of course, you could do it all from the top control if you wanted. The range seems to be great as I walked outside on my back patio forgetting I was connected and it never missed a beat. This is heavy like the ULT 10 because of the battery but moving this around has been zero issue. I was able to sync up all three in the app to test out music playing. They all 3 synced up but the older XV800 seemed to be just slightly behind the other two. When I played just the ULT 9 and 10, man, it was loud and full in this house. Lastly, the sound seems more full and authoritative. Bass just seems to hit and fill every area no matter where I place it. I found when it is sitting near a wall about a foot away, the reflection affect seems to make it feel like I am listening to two or three of these. I REALLY like this speaker and will be using this constantly on my new back yard patio this summer! EXCELLENT job SONY!

      Hi EmanuelS,

      Thank you for your feedback on the SRS-ULT900.

      We would like to clarify that a physical remote is not required to manage the speaker's settings. By downloading and using the Sony | Sound Connect app on your smartphone, you have full control over the unit, including the ability to adjust the volume and use the Equalizer to customize the treble and bass levels to your preference.

      The app also provides access to many other functions, such as lighting control and software updates. You can find more details on what you can do with the app here:
