You can ring or email asking them to do a visual inspection or send some detail pics of the item you are interested in.
I have bought Bax b-stock without issue, I have also returned a pristine beyerdynamic dt700 pro headphone to them because I didn't like it's sound (chose a Sennheiser HD 25 over it).
They are actually shop based, with stores at several locations, and a huge warehouse for the internet stock.
