The Gadget: This olympus microphone plugs into a recorder and your ear, recording whatever you hear. That makes it perfect for recording cellphone interviews, which traditional telephone voice recorder setups meant for landlines can't.

The Price: $18

The Verdict: Perfect for journalists, lawyers and students. Comes with different soft earpieces and jack adapters. I love it. Sound quality of the recordings is as you hear it, which is to say as good as your cellphone delivers. If you're recording by cellphone using a native app, that's going to be better, though.
