Adapts To Your Ear

First flexing technology adapts while you wear them. Producing an amazing podcast, audiobook and call experience.


92% of people get ear fatigue from 45 minutes or more of earbud use. That calls for an earbud revolution.

Say hello to Buderflys.

Your Body Heat and Movement Create A Bespoke Fit And Comfort.

The Buderflys Effect: Listen Longer, Change Your Life

What makes Buderflys different?

Since your ears move and change shape every time you move your head, neck, or mouth, hard clamshell-shaped earbuds cause painful friction and fall out. Buderflys are built with a patent pending proprietary form-flexing compound that allows the bud to fit snugly in your ears and move with you. Our proprietary material uses body heat to mold to your ear, meaning they fit your unique ear shape every time you put them in, and feel more comfortable the longer you wear them.

Can you use Buderflys for music or are they only for audiobooks/podcasts?

They are for all audio! We have developed a sound signature that has extremely high affinity for the spoken word while allowing for a wide soundstage experience for music.

I have big/small/unusual ears. Will Buderflys fit?

Absolutely! The hyper flexible earbuds mold to your ears to give you a snug fit no matter the size or shape of your ears.

What is your 90-day risk-free trial?

Your 90-day risk-free trial starts the day your Buderflys are delivered. If for any reason you are not satisfied, you can return your buds within 90 days.

Do I need a wired cable?

No, however, it does enable you to keep using your buds while the tether is charging, and also lets you plug directly into your devices (like your computer, for example). You can find selected wired cables in our accessory page.

Are Buderflys wireless?

They are connected together by a tether, but use Bluetooth 5.0 to wirelessly connect to any capable device.

Are Buderflys water resistant?

Yes, they are perfect for running in the rain. However, they are not waterproof, so submerging them in water will ruin the earbuds.

How do you clean Buderfly earbuds?

To clean your Buderflys earbuds use a lint-free cloth very lightly dampened with water to wipe them down. Do not submerge your earbuds in water to clean them and do not get liquid in the openings. After cleaning, do not use your earbuds until they are completely dry. Moisture in your earbuds can cause temporary performance issues. Do not insert your earbuds if your ears are wet. Always dry your ears completely before inserting your earphones.

A modern solution to a modern problem for every self-proclaimed geek who just wants to keep their favorite podcasts and audiobooks in their ear all day long.
