I ..habe decided for the Sport edition of the classic Koss-Str. At all me accessible playback devices (Sony Hard Disc player, home theater system, mini disc players and portable stationary, Discman) tested must be the sound of min. Attribute 4 points. "Only" because the 4 per Sportal tends a little distorted bass and with 103 db is not able to weak music sources significantly aufzupushen (especially when weak staffierten new Sony Walkman of relevance). But he gets the full package, it pops quite formidable in spoons. Audiophile course that is not particularly well balanced and not too, but nevertheless brings fun and not 'nerves. At the home facility with corresponding output power of Koss is obviously hopelessly overburdened and can not be hergenommen for what should be obvious. But now the real problem: Unfortunately must confess that neither the comfort nor the processing particularly appealing. The advertised neckworn variant is not only uncomfortable but the shells raise in this way carrying slightly so that one no longer has the full contact, among which, of course, suffers the About conference. Acquired especially for sports use, makes you feel at every disappointment wide, the musical listening while jogging wishes. If one selects the ordinary carrying method, one naturally wonders rightly, why has not acquired the much better sounding narrow Porta Pro.
