Well, this is going to put the cat among the pigeons. But I received my Amiron home's today, from Amazon, and my personal opinion is that they are not worth the money. Not by a long shot. Having had the DT1990's, the Amirons, to me, seem an all round diluted version of the DT1990's. The sound is warmer (I read that as less clarity), yes. Some may like that, but I don't. I knew that all along. I like exact sounds, not the fuzzy version. OK I exaggerate, but that approach to sound is not my preference. I had thought "warmer" meant "nicer to listen to"... but then what does that mean ? Something different to each of us I suspect. But sound reproduction disappointment notwithstanding my greatest problem is the build quality. Somebody on here said the pictures don't do them justice and that although they are mainly plastic, its all high quality. I guess they must have had a better set to mine then, because every time I moved my head even slightly, the damned things creaked and I got a shot of plastic clicking against the yoke. Unbelievably annoying. Even the cable design smacked of cheap to me. Thoroughly disappointed and these will be going straight back to Amazon tomorrow morning. As for what phones I end up with.. not sure. Most likely the DT1990's.. For less money you get more accurate sound, better build quality, greater listening experience options (different earpads) and that seems much better value to me. Its just almost like Beyer have made the pro series (in the DT1770's and DT1990's) and then thought to themselves, "lets make something that by marketing, appeals to the home listener, offers less value for money, costs us less, and charge more for it". Nil points from me on this one BD.
