First of the positives: The handset is really great packaged in recycled cardboard and so that everything is easy to pack again - unlike the Sennheiser RS 160, I tried before, which comes in an unspeakable, sealed blister. The sound is really good, there's nothing to complain about, with a strong, clean bass. A noise I could not hear absolute. Construction is very simple, only the handset must be switched on (not station). It can be good to put in the tray and is stable. In addition, 700mA-Philips batteries are about the Sennheiser the only (affordable) 600mA batteries from GP were. Now the problems: Comfort is standard: Continual light pressure from above (spring-loaded belt). While walking the entire handset springs with audible creaking through the strange suspension with spring. But the worst is the imitation leather, the ears are (almost) airtight and sweat after a few minutes. In addition, opening the battery cover is not easy: Pull slide switch, but nothing beats on, trade is well finished round and not even open with a fingernail - here clearly lacks a recessed grip. And for me the KO criterion: The range is not so great. Just like the Sennheiser dropouts come on a stick already, when I stand 2 rooms away, and in between is just a wall, much of it is completely open - no way creates "5 walls" between them, such as AVF image writes. By the way: "test" judged all digital wireless headphones in Test 2009 in this area as satisfactory, the analog well. This could therefore a fundamental problem of the high frequencies to be (2.4GHz). Good sound alone is just not all - I do not understand the developers because, because nobody is testing such products as we do, so practical? So who gladly wants wirelessly and in the vicinity of the plant (without partitions) listen with very good sound and can make compromises in comfort or insensitive (as the Sennheiser is better, but it has other problems, s. There) is, with Philips well advised everyone else does.
