I bought the BD005 Pro based on Kinera's reputation and truth be told I was seduced by the red/ruby colour. Firstly let me say that std cable and tips did not work for me, but with some SpinFit 145 and Faael hibiscus cable things just came together. Sound is very relaxing, nothing stands out as excellent and no flaw can also be pointed out. It is a competent IEM capable of satisfying most people. Secondly what I did find dissapointing is the colour...it looks brown and that was quite frustrating...perhaps Kinera will fix that. As for the seller ...highly recommended... amazing professionalism and always open to help.
