Frequently asked questions

Weight: Most comfortable options weigh roughly 5 to 9 grams per side.
Material: Look for soft silicone/cushion contact points and flexible shape-memory titanium C-rings.
IP Rating: Look for IP54 or higher if you plan to use them for heavy gym sweat or outdoor jogging.

Design: They feature a C-ring or bridge that hugs the outer ear (anti-helix), leaving the ear canal completely open.
Technology: They use air conduction to direct sound toward your ear opening while preserving full ambient awareness. [1, 2, 3]

Causes: Earwax or dust blocking the speaker mesh, active phone volume limits, or low-quality Bluetooth codecs.
Fix: Clean the speaker mesh gently, disable soft-limit volume settings on your phone, or reboot the device. [1]

Causes: A pairing mismatch between the left and right buds, or dirty charging pins preventing proper contact.
Fix: Place both earbuds back in the charging case for 10 seconds to reset internal pairing, clean the charging pins, or unpair/reconnect them in your phone's Bluetooth settings. [1]

We will work quickly to ship your order as soon as possible. Once your order has shipped, you will receive an email with further information. Delivery times vary depending on your location.

Causes: Most water-resistant or waterproof earbuds (IPX ratings) are built for sweat, rain, and light splashes—not submersion.
Fix: Avoid swimming or exposure to hot water vapor and steam, which can break internal seals and distort sound. [1]

Fix: Turn off Bluetooth, "forget" or unpair the device from your phone, reset the earbuds (often by holding the case or touch button for 5–15 seconds until the indicator light flashes), and re-pair them as a new device.
