If your spending a lot of time online your more likely to be introduced to anime/weeb stuff and fall down that rabbit hole. Also if your on the computer a lot you're probably listening to music and that music might as well sound good so you become an audiophile.

A lot of weebs are also really into anime soundtracks/vocaloids/V-tuber music/Denpa/J-pop and other heavily anime influenced music. It's not surprising that there is significant overlap between these nerdy interests and hobbies.

Anime is getting pretty mainstream in much of the world, it isn't off putting to younger people. Even moreso in Asia, where most of these brands are based.

If anything it's weird that this sub often reacts so negatively to anime mascots when so much of modern entertainment is influenced by it or shares the same roots these days. Here in New York at the mall near my university pretty much every store has a section for some sort of anime merchandise, be it statues, clothing, anime blurays or books. Even various big tech companies have anime mascots they have used for advertising in Asia.

For instance, gaming is pretty mainstream these days, both Sony and Nintendo are giants in the industry and both are Japanese, a significant portion of the games on their consoles are either anime style or have similar roots. Thus it's also only natural that those people are at worst indifferent to the style rather than actively put off.

Well, it is! Look at the video game Cyberpunk 2077, they released an anime and boom, player count skyrocketed but the game is still anything but perfect if you look at all aspects that aren't story telling. Same goes for new IEMs.

Like slap anime onto anything and the weebs will come and eat it up, even if it moves in the garbage territory in terms of quality.

Some weeb things are nice, but most are a cash grab, a few are both. Anime is ridiculously popular, so might as well cash in on this form of media by targeting the ones that are deep into it by providing questionable waifu material.

I personally like it when my products are clean and without these designs. Like the packaging alone makes me not wanna buy some IEMs.

Well it’s a Chinese brand. Having grown up in China, weeb stuff is a lot more mainstream/acceptable there.

Majority of people that brought Moondrop products probably don’t really care. But there could be a sizable demographic that could be attracted to it due to this marketing strategy vis-à-vis to a even smaller demographic people who are turn off by it.

all those shinjis with their iems man

I absolutely hate drawings on my product boxes! I love boxes devoid of any imagery whatsoever! /s
