I would recommend not buying these shoes from any seller other than Sorel. The HD598SE is splendid! My biggest gripe are that the stock tip are fairly small, so I swapped to some more standard Sony types silicone tips. but quality seems ok. Much better than the cheaper stereo headphones I previously had. "Med" to "Low" is good for most applications even on country roads at night. A six might be better for length, but I also have a very slender foot, so a six might be too loose fitting. Oh boy was I wrong when I search for replacement. The Recycled Firefighters #10 YKK reverse coil zippers slide like butter out of the box, however after installing these the zippers slide unbelievably nice! (I really like Sennheisers attitude to spares, they even provided me with new earpads for my treasured 1970s reference cans which are still working perfectly !
