The Sennheiser PXC 310 I for a week now in use and have to say it is an ingenious part. The sound of the headphones is very good, in the depths of the bass can hear very differentiated. The heights are also very nice and pronounced in disconnected noise cancellation (NC) is a real treat classical music. Now for the second and more important part of what makes the NC. My application is for the train, and the open-plan office with instruments (sounds similar to an airplane). It turns on the noise cancellation and noise of the fan falls silent almost completely. The voices of colleagues are very well hidden. Here is the new Noise Guard 2 a very nice development for Noise Guard Advanced, the background noise that could be heard in quiet passages is really almost gone and effect is again erhöt. On the train, the effect is even better, we hear nothing more. Unfortunately lack the bass a little if the NC is turned on but that is not much and is okay (I personally believe that you would not perceive the bass in a louder environment so). I could test my next PXC 310 a Bose QC15, Bose QC3 and a Sennheiser PXC150, others have fallen back to the dealer. The Bose because they were poor and the sound of PXC150 because he was too big for me. Even after a long day press the headphones, but the need to find out whether they are individually each himself comfortable for a itself. The battery lasts 20 hours, and its is quickly full, which is also so in the product description. The new TalkThrough function switched off the music and lets vocal frequencies is a nice gimmick, but nobody needs. Further adapters for the aircraft may also be supplied, and a carrying case is also included. In conclusion, I recommend buying only absolute who is looking headphones with NC, who have a good high-fidelity sound, should look at the PXC310 definitely / hear. They are absolutely worth the money.
