Recording Telephone Interviews

I’ve tried so many things at this point but I’m gonna try another. Just put in my order for the Sony ECM-TL1 Electret Condenser Earphone-Style Digital Microphone. I really look forward to it because it would mean telephone recording with ‘unwired’ freedom. You can record from even a cell phone or a public phone, everything you hear. I just hope it doesn’t pick up too much ambient noise. Will report when I get it.
