i've heard both The Golds and TF10s
IMO TF10s sounded better,the bass hits harder, everything just extends better and being more aggressive, with wider soundstage, more 3D feel and the sound even dramatically improved with amps.
Except for the fit, they're just one of the hardest-to-fit IEMs with it's big housing that sticking out of the ears
(would make you look like something strange and someone may make fun out of you lol)
the cables are not so durable too, some people said that they have to replace their cable sooner than they would wanted to
but the cable is removable, so aftermarket cables are something you could use and that may improve their sound even more.
On the other hand, The Golds have somewhat smooth sound signature, everything just "go-together" in their narrower soundstage. They didn't sound bad at all but just not as fun or as great as TF10s
But they're more comfortable, their cable lasts longer (but not user-replaceable, so use your lifetime warranty)
PS. strong bass with great highs and mids? try westone 3 / 4
