It was also clear from looking at Hifiman's wood choice that it was an extremely cheap, fast-growing wood with VERY wide rings.
Sony's wood has many, tight, slow-growing rings in the wood, and the ES-R10 (from the photos posted) seems to be a little faster growing than the Sony's, but nowhere near as fast as Hifiman's choice.
