ISN Audio H2

I’m probably going to take a chance and say I like the imaging and expansion going on with the S2, though depending on who you are, the H2 could be the ticket. Yet I never missed the bass in the S2, it seemed just to suck-out a slight bit of authority in S2 playback and replace it with stelar treble energy. Maybe the best thing would be to have the S2 and H2 and use them according to mood, as both are a winner with the Penon Serial and better than the included SC819 cable!

The H2 is a natural upgrade from the OS133. It simply does everything with not too much of anything yet also upgrades what you love about most from your IEMs. What I mean by that is it is well known in the industry copper gives you the best natural tonality, body, warmth bass and versatility, then when you add silver plating it upgrades the transparency and detail aspects for the copper base cables. While not at the level of transparency of the S2 and not exactly the warmer leaning C2 either. It does a bit of both.
