Controlled, comparative double blind listening tests on different in-ear (IE) headphones are logistically impractical. One solution is to present listeners virtualized versions of the headphones through a high quality IE replicator headphone equalized to match their measured frequency responses. To test the accuracy of method, ten trained listeners evaluated the overall quality of both actual and virtualized versions of twelve different IE headphones binaurally recorded and reproduced through replicator headphone. The results show evidence that the virtualized headphones produce sound quality ratings that are similar to those produced by the actual headphones.
