They are not well known here but there is a little bit of stuff, just finished listening to three of their ultra budget IEMs and they were not for me. The Remax 610D (which I own) is a nice IEM and very different from the S1. Still curious to hear about the Remax RM800MD also? They make a billion different USB cords and battery packs, basicly anything to do with phones, it seems. Like anything from China at this price range I think quality control may be an issue, though the Remax stuff comes with warranty paperwork as well as batch identification and quality control signatures. It's just that the pure numbers of stuff made is staggering with a company like Somic making 2 million pairs of headphones a month, even if we never hear about them.
