Riiicola! As much as I’d like to ridicule the outsized proportion of this Natural Acoustics iPhone Amplifier compared to the iPhone, it is admittedly a gorgeous piece. Made of ceramic, this handcrafted passive amplifier projects music via it’s natural horn curvature shape without any power. The horn speaker sits atop a walnut base. The whole thing just looks pretty stunning, a functional conversation piece for your living room or bedroom. At $499, it’s not too bad if you consider it as both a decoration object and a speaker.
