With the Cutebeat BT in place you can turn it on and let it seek for Bluetooth connections.
The short Cowin manual talks about default passwords and keying in a PIN but I didn't have to worry about any of that nonsense. I simply enabled Bluetooth on my Nexus 4 phone and the two devices made a connection.
When I am traveling I listen to music on my iPod as I hate the idea of flattening my phone battery so I didn't much like the idea of transferring a load of music from my PC to my phone.
Besides, that would fill the meager 16GB capacity of my phone in short order and that really doesn't appeal to me.
Instead I installed the free Synology DS audio app from the Google Play Store so I could play music from the DS414j NAS I had installed on the network and within moments I had a list of music ready to play.

I cannot claim the Cowin Cutebeat BT is a Hi-Fi device however it is a dramatic improvement over the speaker in my Nexus 4, and no doubt it will make your phone sound better too.
I was surprised to find the Cowin Cutebeat BT compares tolerably well with my Sony in-ear headphones both in terms of quality and volume. Realistically the Sony's come out ahead in every department, however I expected them to trample the Cutebeat BT under foot and that wasn't quite the case.
You can hear the Cowin speaker in action on my video clip and right at the end you'll hear the audio drop out for a fraction of a second. That happened a few times to me and could be an issue either with the link to the NAS or the Bluetooth between phone and Cowin speaker. It's not the end of the world but did cause me some minor annoyance.
I cannot really put a figure on the volume of the Cowin Cutebeat BT as it clearly depends on the digital files you are playing. The loudest level I recorded was 67dBA and my overall impression was that the speaker was just about loud enough, provided you use it in a fairly quiet room or you want some background music.
When the volume is cranked to the max there is occasional distortion that vanishes when the volume is decreased one click.
