For the line art, I'm looking for something less shaded, more 2D and flat. Think of it in terms of a stencil, perhaps... The microphone is nice (considering it is in the original photo), but isn't a required element in the logo going forward. And a proper wine glass shape is what I'm after. I don't know about the "3/4 portrait" orientation of the headphones on the glass either; I think my 2D preference precludes that.
I'm also wondering about the typeface, since it seems too open, the x-height is too high in relation to the overall letter height. I'd also like to see some more masculine and heavier type examples.
I'm liking the direction you're headed with this one. The wine glass is overly simplified, but part of that is to suggest the shape of the wine glass instead of actually outlining it. The headphones too are very simple, perhaps too simple for my taste.
The typeface is ok, but doesn't appeal very much to me at present. I'm not a huge fan of all caps (though sometimes I can see doing small caps). The color combo is actually quite good.
I can't quite make out what the wine glass has in it. I'd say it was part of a wine bottle! That graphic has a lot going on, I'm left speechless.
The work with the typeface is interesting in that it breaks the monotony. It's still subject to my earlier comments about all caps, but it's something I haven't seen before, so that's nice!
I have provided you with a few different sample of a basic design. Each element can be rearranged for you to better suit your needs. Please feel free to submit feedback for the designs you prefer.
