Sennheiser wants to improve the audio quality of customers' smartphone videos with the Memory Mic-- a Bluetooth device the company claims recordss "broadcast quality" sound.
The Memory Mic clips on clothing magnetically, and records up to 4 hours of audio. It pairs with smartphones via Bluetooth, and continues recording even if it loses connection with the phone. The phone still continues recording ambient sound, and once a recording is done the user can sync both audio streams and video via companion app.
