Hi Tino96 on Friday 19 October 2012 I had the opportunity to try the new Sennheiser Momentum, it had good isolation excellent quality of sound - fairly neutral sound signature, works out of a iphone or ipod and compared very favorably to the Sennheiser HD650 in terms of sound quality. I tested this HP also with a portable HP amp ALO RX MX2 & algorythm solo portable DAC. The HP was very comfortable - leather pads and I think retails for around $350 USD. For the price I think this is excellent bang for buck HP. Aside from the HD800 this Sennheiser is IMO the best Sennheiser HP price to quality ratio. I also listened to the HD700 (with CD play & Lehmann Black Cube HP amp) and was not too impressed for the price. Might be worth your while to listen to Momentum if you get the chance.
