I'm sorry, but I think i'd have to disagree here on two points (one which is completely subjective). 1) I found, after ABing both gen 1 and gen 2 for the past few days, that the Gen 2 bass is a lot more forward than Gen 1 (It doesn't necessarily have more bass, because the Gen 1 can really drop when need to, so long as your environment isn't too loud). This does mean that, though it does not "flood" into other frequencies, it does in fact veil them slightly on the Gen 2. Now this is talking about veiling already incredibly detailed and clear headphones, so their still a cut above the rest when it comes to clarity. But I noticed on the Gen 1 that the vocals were the star, and on the Gen 2, the bass and the vocals are having some kind of duet. They share the front spot, making the vocals seem a little less detailed, as if covered by a slight haze, even if they may not be. Maybe more burn in time might fix this. The fact that the Gen 2 can go louder probably adds to this effect too. I think that the bass in the Gen 1 is far nicer to listen to if you are using these indoors. If you are using these as portable cans, then you're better off with the more forward bass on the gen 2 as it will be pushed slightly back by ambient noise anyways. It's not a huge difference, but to me it was clearly noticeable. 2) I'm pretty sure both Gen 1 and Gen 2 have the same frequency range (20-22,000hz), so I don't think either can reach more or less notes than the other. I think the difference is in the forwardness of each frequency and in the quantity of bass heard. However, I do agree that the Gen 2 is the overall safer and more versatile option. They both sound amazing, but they sound different enough to be considered different headphones. The Gen 2 will give you a more consistent experience in different environments and with different amps and what not. The Gen 1, though personally my favorite sound, is fairly dependent on ambient noise (especially lower frequencies like the rumble from the road when you are in your car, etc).
