I'm still not sure how to work this cheap but effective digital tape recorder. I already accidently the best recordings I'd ever heard, of a boy in a chapel in the Iron Island Museum in Buffalo. That was a scary night with the PIST101 crew.
However, I find listening to EVPs difficult and frustrating. I know I have hearing loss, likely due to the many WHO concerts I've rocked out to over the years but once in a while, I can hear a bit of something. Or maybe I perceive a sense, a vibration slightly different than other vibrations that the current batch of voices is creating.
Once I hear evidence with the "ghost voice" pointed out, I can 70% of the time hear it as well. That doesn't mean I believe it's a ghost but at least I can hear it enough to discern there is another sound there.
Some EVPs can be very clear. I've heard them myself.
But for the most part, it's a very long painstaking process to analyze your EVPs.
I've bought four different sets of headphones, none of them terribly expensive although two were excellent deals.
It did help a bit sometimes.
However, the whole process of EVPs takes a long long time.
You have to transfer the recording into a special program on your computer. Most of the time, if you have a cheapie record such as I, you have to do it in real time. So twelve hours of EVPs means twelve hours of watching that your computer doesn't go into screensaver or power off in the middle of a recording.
Then you have to sit and listen and listen and listen.
Your program, depending on what you use, I use a free one from the internet, might allow you to edit and boost the sounds of intriguing portions of your tapes.
There are websites where people upload their evps, photographs and other evidence for others to scrutinize.
When you're listening to your EVP, relax your ears and be open to any aberration in the sounds.
There might be a whisper, murmur, moan, laugh, scream, crying and so on.
Be open minded and listen in a very quiet place, no music or TV in the background.
When you're recording your EVPs it's helpful to state where you are and the time before the session. Describe any unusual sounds or if someone trips or sighs or walks over head. You'd be surprised how fast you forget what really happened in that room months later when suddenly think there's a monster banging at the window.
Keep notes in a notebook too if you remember or have the means. Write down the numbers of files, tracks and so on and where they happened and the time. Also make notes about anything usual to listen for or eliminate.
You'd also be surprised how loud and creepy a stomach growling can be. Make sure you note it when it happens.
The more notes the better although it can be distracting while you're trying to watch for evidence.
Another thing I've come to realize is that taking pictures while doing EVP can be distracting because whenever you hear the clicks, you get excited to think it's something but it was just a camera...
