EAR-CLIP REVOLUTION: ZERO-PRESSURE ADAPTIVE FIT - Revolutionary self-adaptive titanium memory wire + skin-friendly liquid silicone delivers fuller wrap and 88% better elasticity — locks gently around your ear like it was custom-molded, invisible comfort for 10+ hour wear, even with glasses or helmets.
CINEMATIC BASS THAT HITS DIFFERENT - Upgraded dual-magnet titanium dynamic driver + exclusive chamber design unleashes explosive, chest-pounding lows that destroy every other clip-style open-ear bud — finally, true heavy bass without sealing your ears!
56 HOURS TOTAL BATTERY + DETACHABLE WASHABLE CASE - 8 hours from the earpieces + massive 48 hours from the sleek charging case. Industry-first removable magnetic lid lets you pop it off, rinse clean, or swap colors — stays fresh forever, no more sweaty case smell.

IPX5 SWEATPROOF + POCKET-SIZED FASHION STATEMENT - Built to survive torrential downpours and the sweatiest HIIT sessions. The textured fabric-wrapped case is smaller than a lipstick — toss it in any pocket or clip it to your gym bag and turn heads everywhere.

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.
