I purchased Pimsleur's conversational Turkish and loved it. The speakers' voices are clear and easy to understand and mimic. Overstock was out of the next version of Turkish, so I decided to try the Chinese. The English speaker's voice is much louder than the Chinese speakers. The male voice is very hard to hear and understand. The audio is not mixed very well. The voices are not balanced. I would not recommend it. In the meantime, I did get the comprehensive Turkish set. Be forewarned if you have the conversational version and get the more expensive ($200+) comprehensive version, the first 15 lessons are the same as the conversatoinal and you only get 15 additional. Very frustrating.
