Yes it's normal. Mine also looks like that.
Mine isn't like that. All of the holes in mine are punched all the way through.

Don't mind the pocket lint. That's the best I could do as I don't have a macro lens for my DSLR. You can slightly see the 3 holes up in the middle top for the mic (I assume) but otherwise they looks more or less the same.

Those were the best I could do, sorry they're a little blurry. I tried to get it under a lamp and under the outside light through a sliding door, but neither showed what the OP has. There might be a very slight difference in some of the holes, but it's hardly noticeable. The first M8 I had though had a little bit more like what the OP has, but on the top grill. It still wasn't that bad though.
Hello,
I want to know if the following in the picture is normal.

The sound is good, but I'm not sure if that's like a kind of glue or if it should be there at all.
Could I perhaps unblock them with a thin needle or something?
Thank you.
