Well, Negakinu got me listening to the Pistons and MHC1. And guess what? He is right...well somewhat. The Sont is richer and more refined, especially in the mids. Vocals are stunning, and I had forgotten about that in the MHC1. I had initially said the Pistons sounded better, but I had the wrong tips on the Sony and I took a quick listen. But I have UE900 tips on both now and the Sony clearly wins. Pistons aren't miles behind though,and the Pistons have more bass, treble, and a wider soundstage. The MHC1 seems to be a mid focused iem with good bass and decent highs. Highs may not be enough for some but are perfect for me. I will try to get to the On1 a little later vlenbo.
Yup, exactely. The Pistons are still a good value though and have some things going for them over the MHC1, namely the packaging, cable and, for me personally, the fit. The MHC1 wins on sound alone.
