Thing to note, bamboo in Asia is cheap, so it being made from real bamboo isn't really a selling point.
I remembered something about bamboo's sonic quality being poor when compared to mdr whilst researching A5 speakers. Apparently, bamboo isn't a good material to use if you like bass. Something abt the wood being porous?
Anyways from the mini reviews, this would be consistent with what I found.
