OK, I understand. However, I think it is very misleading to make such modifications. The original review-er never specified that what he had was an engineering sample (did he even know?). IMHO a product sent for review should be as close as possible to the one that the consumer will buy, otherwise this type of reviews cannot be trusted.
Supposed I really wanted a certain type of earbuds that I know fit my ears and imagine my surprise when the ordered packaged does not contain them and the IEM don't perform that well as a result. This is especially the case for Brainwavz earphones that do not have the standard earbud inner diameter(like Senn, AKG, Xears, etc).
Well in fairness we do state the listed accessories on our site. D2K didn't get a engineering sample, the earbuds that were to be included were not ready, so we sent the eartips from the M5, sorry for any confusion. You can always send the earphones back for a full refund if you are not happy with them.
