KingOne 金冠 K5 Bluetooth Portable Speaker (Made-in-China)
Been seeing many different made/type of speakers in China, some of them are quite good
Like this "KingOne" brand (name seem rather exaggerate to me 
), built quality & sound is good, especially the vocal & mid 
Product photos & unboxing ...
Packaging is nice, good presentation as well 
Metal goldish box, with the logo KingOne 金冠 on top center, looks serious stuff man 
Size comparison with Nexus4
There are few colours available, but I personally prefer this colour
Touch feel & built quality is good, doesn't really feel like those typical cheapo speakers 
Power on/off, Line-In, MicroSD & MicroUSB charging, all located at the back
On top panel is for touch control, nice feature indeed
Power up !
I like the vocal & mid-level sound, it's clear, though it has some audible phssing sound while not playing ...
Overall it's good performer, considering it's small, portable to carry, at affordable price
