Cheap accoustic foam on eBay?

That looks fine, but be advised of a few things:

1) Foam like that really only attenuates high/mid frequencies and high frequency reflections. If you're _only_ using the booth for vocals/voice-over/ADR, that should be fine, but you need to take a different approach if you need to attenuate bass freqs.

2) If you're not spot-treating your room for overall even sound/reflections, but really trying to completely "deaden" for a vocal booth, you might need at least two sets of that stuff, which would double your expenses. That gets pretty close to just buying a box of Auralex for $150, which might be a better idea if you're going to need a bunch of it.

3) Sometimes recording can take a lot more time than you think; you or another voice-over artist may be out in the shed for quite some time. I don't know where you live, but have you thought about ventilation, A/C, and/or heat for your booth? Don't forget about that, and also about the sound considerations that you'll need to account for...

Hi,

Do you own one? What do you think?
The reviews I've seen and read were very mixed at best, and being a studio owner, I find it hard to believe that it could replace a real booth (although I'm sure it would be an improvement over "nothing").

But I must admit no personal experience with it, so I'd love to hear from somebody that owns one and actually uses it...

1) That kind of foam is only good for reducing a bit of high frequency reflection. The thinner, the less effective at lower frequencies.
2) That kind of foam does nothing for sound transmission through a wall. Only mass can do that. I hope your shed is in a quiet neighborhood.
3) It is unlikely that the foam is flame resistant. Some of it is quite flammable. You can make quite a fire trap from that stuff. Prohibit smoking.
 
Ditto on Richard's comments. Flammability and thickness are two areas that cheaper foam usually doesn't help much with.

A few years ago there was a cheap foam manufacturer that claimed as good of NRC as Auralex but didn't have lab reports. Someone on gearslutz did a comparison between them and it wasn't all that close. Any open-cell foam will absorb sound, but cheap foam doesn't absorb nearly as much.

And yes, foam does nothing for sound isolation. If the place isn't quiet, you need to take a look at building up your walls/windows/doors.
