I wanted to thank everyone who has reviewed the pro2900, because I did not think to buy it at first, having already the 900, but I'm very happy to have listened all of you, lol.
I use pro900 mainly for gaming and movies, sometimes for a bit of electro and hip-hop and it's perfect for these kind of music, but for the others ...
Loving beautiful voices/midrange, pro900 was very disappointing, but I don't expected more with all the existing reviews. Pro2900 is really, really very different from pro900. Clear, very detailed like the pro900 but much more beautiful midrange, more emphasized, an excellent soundstage, more warm, better bass, less boomy, more real, but still very present and very punchy, ultrasound oblige. Beautiful high without sibilance.
Like all others here, I certainly agree that this headphone is really underrated, everyone thinks that it is only pro900, but open, but not at all, it's completely different, a delight and really an fantastic all rounder.
If I had to give one small complaint, pads of pro2900 are a bit smaller, so the ears can touch edges (no problems with mine,lol), but it's really a detail.
For 380-400€, a must buy.
Sorry for my bad english
