i have them. they're pretty light on the type of bass that EDM, rap, pop or any of those typical genres expects of them but if you play something with low frequency it can pull a bit of rumble. they are neutral sounding, very detailed, wide soundstage and for acoustic or orchestral music they're pretty good. even though they don't have edm type bass, they can sound pretty good when you listen to a cello. they're a little less dynamic than other headphones that it competes with though. i've had mine for maybe 8+ years and they're still going strong. replaced the pads with some dekoni velours and they're ok. mine are made in austria so i credit that to their longevity.
i've not tried the audio Technica that you have so i can't really compare the two but the k702 i know well, and it's surprising that they're being described as bassy.
