In this Video George Whittam (director of Technology at EdgeStudio) compares four portable vocal booth solutions for Voice over work:
Porta-Booth Pro by Harlan Hogan, Kaotica Eyeball, Carry-on Vocal Booth 2.0 from VocalBoothToGo.com and FlexiBooth from Primacoustic Acoustic Solutions.
You can hear how they sound in comparison to each other.
George did not share his personal preferences, but you can clearly hear the difference in sound recording.
So you be the judge.
(Of course we believe that our booth sounds the best!)
