sat down with the senn 650, grado hf2 and recabled koss75, all into an mstage..............Pink floyd dark side, Bad CO s/t, connells fun and games, cannonball adderley/miles davis somethin' else, zz top rio grande mud original lp pressings was the source material on a rega p3/dynavector..............regardless of the price, the little koss hold their own. The senn is more of a 'headphone experience' in that it has more extension, soundstage and affect, but the koss is the more natural dynamic and true of the three in terms of the basics, which to me is the accuracy of basic instrument reproduction such as guitar, cymbals, bass kick snare drums, piano etc. I just plain want to listen to the koss more than the other two and it has a very nice airy and balanced sound that the other 2 don't quite give............. The senns really have the nicest vocal which is quite enjoyable, upfront and natural, but that is only because they chop out alot of sound, mainly in the upper mids and how they do that while still giving such nice vocals is a mystery, but it's a fact to my ears that the senns achieve their unique and enjoyable quality at the expense of upper mid detail and upper end accuracy. By chopping out the upper mids, the mids that are left, come through with the senn magic somehow which is a little artifically compressed but in a nice way. This is the most characterisic aspect of sennheiser sound signature imo........They had the least accurate and realistic treble/cymbals to my ears and the most closed, flat sound of the three. This is a little flat, unalive and undynamic headphone imo . The grado's have the truest cymbal presentation by far, decent mids but somewhat murky and overbearing lows (which should get better after burn in - these are brand new). But still the koss are no slouch and for my tastes and record collection, sound enjoyable, true and alive. And while I wish i could tweek a couple things on them, they still sound quite nice with a recable and amped up.
