This works great. As a newspaper reporter, I do phone interviews and that's perfect for that. You just plug it into your recorder's mic input (I use a Sony recorder but I think any brand will do) and then put the earphone in your ear. And, of course, hold the phone to your ear. It records clearly, with no glitches or anything like that. Just be careful not to plug it into the headphone jack as you'll only have a full record of your conversation but you won't be able to hear the other person. Was there, made it, had to call the man again and interview him again. No fun and a little embarrassing! I've actually had 4 or 5 of these over the years and always buy this brand because I know it works so well. It's not like they're cracked (although I've had one case where the earpiece was cracked, but that was a few years ago). I usually lose them. Of course you should always check the laws in your state, but where I live you can record phone conversations if either party (me) knows a recording is taking place. Some states may not be. But I tell people (usually) I'm recording them. record exactly what they tell me without having to take obscure notes while I'm talking to them.
