Few months after the first preview / prototype review of the RE252 (known as RE3 at first) hit Head-fi.org, Head-Direct finally released their new flag ship IEM to the market. One of the more interesting thing about this IEM is that its outer shell is made out of soft rubbery material that is supposed to 'lock into' you outer ear for a secure fit. Priced at US$199, RE252 is not cheap. But given my previous experience with the RE series, I think it is a fair guess that it will worth the money you paid for.[UPDATE] I just received the RE252 in the mail. Hopefully the review will come in a few weeks. Stay tuned.
