AFTER 12 MONTHS of using the Sennheiser Memory Mic to create hands-free classroom recordings, I'm very happy to report I have never lost an audio segment with the Memory Mic producing high quality audio or high definition video. I'm now helping other educators understand the simple and effective workflow involved to quickly produce and share recorded minutes from academic settings.
And a big thumbs-up to Christian Payne for introducing me to the sweet little piece of durable technology. The Sennheiser Memory Mic works with iOS and Android. It's much more resistant to water immersions and concrete bounce tests than the handsets I've used to record with it. Recommended.
