Pre-sales start June 2nd at 11:00 AM on CAMPFIRE: The next-gen canal-type bone conduction earphones 'S710' for underwater and crowded trains.
Pre-sales for the 'S710' next-generation canal-type bone conduction earphones will begin on CAMPFIRE on June 2nd at 11:00 AM. By adopting a canal-type structure, it overcomes the traditional weaknesses of open-ear bone conduction models, such as poor bass and sound leakage. Featuring IPX8 waterproofing, 8GB of internal storage, and Bluetooth 5.4, it offers a premium audio experience even during swimming or intense exercise.

Until now, the standard for bone conduction earphones has been the 'open-ear' design. However, this design often suffers from thin bass, poor sound quality, instability during movement, and significant sound leakage. We have developed the 'S710' canal-type bone conduction earphones to solve these issues. Its snug fit in the ear canal improves transmission efficiency, fundamentally addressing bass and leakage problems. It creates a 'semi-sealed space' in the ear canal, blending clear mid-to-high frequencies from bone conduction with rich bass similar to air conduction. With a proprietary directional vibration unit, it reduces sound leakage by approximately 89% compared to conventional models. The physical seal blocks ambient noise, and the design ensures a secure fit even during intense exercise. With IPX8 waterproofing, it can be used at depths of up to 20 meters. It includes 8GB of internal memory, allowing for up to 2,000 songs to be stored without a smartphone. It supports Bluetooth 5.4 for stable connectivity and comes in three colors: black, blue, and yellow-green.
