Already 4 month old news from the VSonic GR07 thread.. :P will have to read how they are though. Love my GR07s and an earbud of similar quality would be awesome.http://www.head-fi.org/t/552132/vsonic-gr07-impressions-thread/7170
I had both a few weeks ago. Tomahawk has an awesome sound that suits most music types, they have fairly extended highs, warm midrange and fairly good lows. RX-1 have a forward midrange and good bass if you can get the proper seal, highs seem a little rolled off... bit more then i like to be honest. I highly prefer the Tomahawk. But id skip both and get the Cygnus or TP16.
