Love them!!!!
These are great sounding speakers. After listening to these for half an hour, then listening to my old speakers, it was night and day. Comparison is watching HD TV then going back to tube TV. It was that dramatic. This is a definitely a great deal. You have to hear it to believe it. I bought two from another site which was slightly cheaper, but looks like Amazon is lowest now. I bought two to connect to each other.
You have two options connecting multiple S3, first is via wireless, other is connecting 3.5mm cable.
Middle B&O button connects to devices:
Hold 2 seconds (first beep) to connect to bluetooth devices (phone, ipad, etc..)
Hold 5 seconds (second beep) to connect to another S3 via wireless
Hold 7 seconds (third beep) to connect to another S3 via 3.5mm cable
It seems if you have two S3 in stereo mode, you cannot have it connect bluetooth and 3.5mm cable. This means that you cannot have it connected to your TV via 3.5mm cable to watch a movie then automatically switch to bluetooth to listen to music on your phone. There are workarounds online if you want to try this. I don't think these speakers are meant for TV surround sound like a sound bar as controlling volume has to be done on the speaker or B&O app you can download. However, these speakers can play music really really really well.
I followed previous reviews and updated firmware on both speakers before connecting to each other. You can use any micro USB to USB cable (i.e. cable from Samsung phone) to connect to the speaker to the computer to update the firmware. B&O does not provide you this cable. After updating firmware, I connected two B&O speakers together. After that, I connected my phone to "master" speaker (first one). As every review mentioned, there is slight delay before music is played. Little annoying, but you get over it.
Sound is fantastic. If you are budget minded person who doesn't want to spend hundreds/thousands, these are great buy. I never heard sound so crisp and just perfect. I
