Opinta Bone Conduction Swimming Headphones 32GB

Opinta swimming headphones are open-ear, IP68 bone-conduction earbuds with built-in 32GB MP3 storage and Bluetooth 5.4 for reliable audio above water and standalone playback underwater.

These waterproof headphones are designed for swimmers, triathletes, cyclists and runners who need clear audio without blocking the ear canal. The bone conduction design transmits sound through the cheekbones so you stay aware of ambient noise, while durable IP68 sealing and a dedicated MP3 mode let you listen even when Bluetooth cannot connect underwater. They also include safety lights, fast magnetic charging and ample onboard storage for thousands of tracks.

How do these headphones work underwater and above the waterline?

Opinta uses bone conduction transducers that rest near the temples, letting sound bypass the eardrum. Bluetooth 5.4 provides a stable wireless link on land; when submerged, switch to MP3 mode to play music from the internal 32GB memory.

• IP68 waterproof rating for prolonged water exposure.
• Bluetooth 5.4 for reliable pairing outside water.
• 32GB internal storage holds roughly 5,000–7,000 songs.
• Four consecutive presses of the multi-function key toggles between MP3 and Bluetooth modes.

What are the battery life and charging details?

A quick 2.5-hour magnetic charge gives around eight hours of continuous playback, enough for multiple workouts or a long training day. The magnetic cable also doubles as a data link for dragging and dropping music files from your computer.

• 2.5-hour full charge time.
• Up to 8 hours of continuous audio per charge.
• Magnetic charging connector for simple alignment and durability.
• Charge and transfer songs via the included USB cable.

How do the safety lights and open-ear design help during outdoor workouts?

Built-in indicator lights increase visibility for early-morning or evening runs and rides. The open-ear, non-insert design keeps ear canals free so you remain alert to traffic, coaches or fellow athletes while still enjoying music or podcasts.

• Press and hold the Light/Volume '-' button for 3 seconds to toggle the red safety light.
• Open-ear fit lets you hear ambient sounds for safer outdoor training.
• Lighted sides improve visibility to motorists and other athletes at night.
• Secure, low-profile form stays in place during swimming, cycling and running.

What about sound quality, comfort and included content?

These earbuds are tuned to provide clear, full-range audio through bone conduction while avoiding ear-canal fatigue. The headset favors comfort with a lightweight build and a stable fit for long sessions in and out of the water.

• Open-ear, non-intrusive fit designed for extended wear.
• Balanced audio optimized for sports and spoken-word playback.
• Includes licensed Creative Commons track: "I'll Be Right Behind You" by Josh Woodward.
• Onboard storage for thousands of tracks so you can leave your phone behind while swimming.

Who this is for: Athletes and active people who need dependable audio across multiple sports — swimmers who require a true waterproof solution, triathletes who want continuous playback between disciplines, runners and cyclists seeking open-ear awareness with added night visibility. If you want headphones that work as a Bluetooth headset on land and as a standalone MP3 player underwater, with simple magnetic charging and long battery life, Opinta’s bone conduction headphones are built for those needs.
