Headphones is the more sensible Inkling of Team Blue. Compared to the other members of the team, who usually have an erratic and unusual behavior pattern, Headphones reactions to situations seem to be the most reasonable and fitting... For example, if a situation seems to be pretty scary and intimidating, Headphones usually responds to the situation by being scared and intimidated, instead of carefree and still smiling. Headphones also doesn't like to argue over little things like Goggles and Specs do with each other, often getting frustrated whenever she does have to put up with the two failing to agree to disagree. While Headphones is easily scared, sometimes even to the point where she's crying, she's working on being more confident in her battles, and even looks out for her teammates like they're part of her family... Sacrificing herself and suggesting and recommending what to do next in order to survive is something that she's pretty keen on doing, as long as her buddies are ok and gain the upper hand in the end! 

For Headphones' voice, I would like hers to sound similar or identical to her previous voice from all of the previous CoroCoro comic dubs that were posted on YouTube before they were deleted. Here are some clips I've saved focusing mainly on Headphones for reference! https://drive.google.com/file/d/1KqE5EkgBNuRcHZ7qMwCRemfLJRx7CSwO/view?usp=sharing
