How the prank works
When your friend leaves their iPhone unattended (unlocked), open Vocalcord or the Shortcuts app, set up a charging sound automation, and walk away. The next time they plug in their phone — at a coffee shop, at work, in a quiet room — the sound plays automatically. No notification, no warning. Just pure audio chaos.
The best part? Most people don't know custom charging sounds exist, so they have no idea what just happened. They'll check their notifications, look around confused, and plug in again — triggering it a second time.
The 5 best prank sounds
1. The Wet Fart
Embarrassment level: 🔥🔥🔥🔥🔥
The undisputed champion of charging sound pranks. Nothing — absolutely nothing — matches the look on someone's face when their phone rips a wet, squelchy fart the moment they plug it in at work. Bonus points if the room is dead silent. Double bonus points if they reflexively say "that wasn't me."
This is the #1 most-used prank sound in Vocalcord for a reason. It's simple, it's universal, and the reaction never gets old.
2. The Loud Moan
Embarrassment level: 🔥🔥🔥🔥🔥
An exaggerated, dramatic moan of pleasure. When their phone does this in a meeting or a library, the social damage is instant and irreversible. The victim's face turns red before their brain even processes what happened. Absolutely devastating in professional settings.
Warning: This one can backfire if used in the wrong context. Read the room. Or don't — that's what makes it funny.
3. The Horror Scream
Jump scare level: 🔥🔥🔥🔥
A sudden, blood-curdling scream. Works best when they plug in their phone in a quiet room, at night, or right before bed. The initial shock is followed by confusion, then the slow realization that their phone is haunted. If they charge overnight, they're in for a rude awakening when they plug in.
4. The Air Horn
Volume chaos level: 🔥🔥🔥🔥
BWAAAAAAMP. A full-blast air horn at media volume. This one works on pure shock value. It's not subtle, it's not clever — it's just incredibly, startlingly loud. Perfect for someone who charges their phone with the media volume cranked. The whole room will jump.
5. The Goat Scream
Confusion level: 🔥🔥🔥🔥🔥
A sustained, unhinged goat scream. The magic of this one is the confusion factor. A fart or scream, people understand. But a goat? Nobody expects their phone to produce a goat. The victim will stare at their phone in genuine bewilderment trying to figure out which app just screamed like a farm animal.
How to set it up
The fastest way is with Vocalcord:
- Open Vocalcord on your friend's iPhone (you need the phone unlocked).
- Pick a sound from the list above.
- Tap to set it as the charging sound (15 seconds).
- Hand the phone back and wait.

How to undo the prank
When your friend has suffered enough (or threatens bodily harm):
- Open the Shortcuts app.
- Tap the Automation tab.
- Find the charger-connected automation.
- Swipe left and tap Delete.
The default Apple charging chime returns immediately. Or — hear us out — set a different sound instead and keep the cycle going.
