Audio Technica has the VW Golf of headphones improves the M50 and brought out the model MSR7. In truth, the newer technology has perhaps brought 5 to 15% improvement. But what has helped even more that the headphones plays more precise is that the inflated Bass (energy) has been reduced from the M50 and thus more precision and heights are left. What distinguishes the MSR7 its ability also quietly still be able to play really well, this is a real quality feature and you are due even later if you can spend more money on hi the more significant products also can still enjoy - as opposed to those which are blow away in the early years with open mobile headphones hearing the long term. Thus, the MSR7 is perfect for long-term listening where you unlike other models - will put away soon - who spontaneously more Anmachfaktor. Like its predecessor, it provides a great timing and organic timbres. The bass is precise but the kick drum from the drum is indeed audible but does not generate the pressure wave of stronger bass headphones. The bass is certainly less than neutral rate but the sound profit in the transients, it is value. I have the MSR7 with the performance of 880 Ultrasone compared the slightly more bass but it brings but cooler and less organic comes along, the bass less precise and, moreover, is more expensive. A B & O H6 plays slightly cooler, less organic, less fully at low volumes but has a better stage-figure. The build quality of the MSR7 is 1A. The insulation is 1A. The comfort is 1A. The M50 was 150 a real price / performance Kracher. The MSR7 I find barely adequate fro the price. The Leisehörperformance and long-term suitability, however, is priceless in my opinion. Which you can currently buy Certainly next to Yamaha MT220 of reasonable closed headphones.
