After my good experiences with the PortaPro it should be a closed headphones, with which I can listen to music loudly, while the rest of the TV family sees. Sonically I can notice differences only in nuances, detailed highs and deep bass relative, maybe a little bit more space because it is a closed headphones. I know only one listener who goes more into the abyss, namely the Beyerdynamic DT 990. My biggest fear was that the listener would sound worse than the PortaPro I almost always carry around with me if music should be there. This fear was unfounded. The processing is very solid and the size (compared to the PortaPro) it is very easy. The cable to the integrated remote control / headset is relatively thick and solid, so that does not have to be a cable break, as reported in PortaPro counted. However, this results in a disadvantage that touches the cable to clothing, hands etc. as contact transfer sound to the listener and the membrane and are somewhat reinforced. I find this but tolerable. The remote control works with iPhone 4S and iPad 3 wonderful, the micro-I have not tried yet, the keys have a solid tactile feedback and they are also to feel good that I can not necessarily be said of the original Apple headset. The comfort is mediocre to good for me, but I am now open lightweight design of PortaPro usual. Since the rated handset is closed, there are slight heat buildup and the pressure is a little stronger, but the strap twinge not at loggerheads. Now a major disadvantage, why I no longer have the phone after one day: No sooner had unpacked the listener already has my 17 year old son is no longer his eyes let him. The Porta Pro he had never worn because of its 80 designs in public, even though it has always addressed the good sound. This headset now appears to meet modern design and good sound. So I packed him and assigned as a spontaneous birthday gift. By the way, I would not with this debris (compared to the PortaPro) on the road cars, but that's probably a generational issue. After I had previously rebuilt my PortaPro cable and headset from iPhone handset ([...]), I'll probably soon be time to try the PortaPro KTC ... Small supplement: Meanwhile, the listener seems "rooted" to my son to be. If he walks around without me, this looks somehow "incomplete" from ...
