This is a premium product - it's sleek and black and stylish and powerful and it sounds absolutely brilliant !! It is a substantial piece of equipment, heavy and has the excellent build quality you expect from Sony. Best of all, it has fantastic sound quality - the bass is deep, the treble clear and the voices have a quality rarely heard, it all fits together perfectly - I have been listening to all sorts of music covering many genres (and years) in my substantial collection and am hearing things that I have never noticed before - although to be fair you get out what you put in so all of my collection is now in lossless Flac. I confess to having a lot of Sony products but they all work seamlessly together from the Media Go software on pc, through the SongPal app on Experia SP to the X99, all are easy to set up and work perfectly - even with each component in different rooms. Having added extra SD card storage to the NWZ A15 it is easy to connect via NFC and the Bluetooth sound is fantastic even if controlled from a distance. I can't comment on other connections as do not have any Apple products or like using Google. Set up from the box was easy, updating the internal software a doddle and connections to home broadband straightforward - and everything is still working without any dropout after a couple of weeks - it is very easy to use. I already have an X77 and the multi room set up is straightforward and works so can use both while inside and out - if only weather allowed! Just one small issue, using the Experia mobile Songpal app through pc does sap the mobile battery over a longish period (few hours in the evening) but guess that is to be expected and it can be charged from another room. Overall, to me, the X99 is a fantastic product, it looks good and sounds simply brilliant. Fantastic!!!

I brought this speaker 1st then the Sony HT-NT3 and was planning to buy additional speaker for other room's. Both the Speakers have impressive sound and could not be happier with the sound or the Bluetooth conectivity, but the moment I tried to connect to Wi-Fi the hole experience changed would not accept Wi-Fi code. Managed to connect via IPad but the Songpal app has been a complete nightmare and very glitchy and music play back stops frequently. If you want a multy room system DO NOT BUY, as individual units they are very good. Overall very disappointed, I have wasted far too much of my life trying to get this to work properly. It should not take an hour to get both speakers playing the same music. These are not cheap and expected better for the cost and from SONY. May only req a better app to control devices ???. and woul like to hear from SONY

Sounds great, but drops Wi-Fi and internet connections after 2 - 60 minutes. Still trying to solve this after 2 weeks. These connections are essential for multiroom operation
