Which thumbnail is more intriguing?

Hi! I'm a designer and I'm working on an app concept that I want to include in my portfolio. I was hoping I could get some opinions on which thumbnail is more appealing if you were to see this. And which one you feel conveys the premise best?

App premise:

EavesDropp - Listen in stealth, save for later. An app designed so you can record audio to your watch or phone. Listen to lectures, song lyrics, conversations, whatever. Record what you want and EavesDropp will save the audio file with transcription. Leave your Airpods in one room while listening in another.

DISCLAIMER: This is a satirical app. It's not real, it's just a concept app so I can showcase my skills. There are legal restrictions to recording someone without consent.

Sorry for not cropping, this is the only way eve allows me to post photos. Thanks in advance!
