GREYOLK Bone Conduction Swimming Headphones 32GB MP3

These GREYOLK bone conduction headphones combine IP68 waterproofing with Bluetooth 5.4 and a built-in 32GB MP3 player so you can listen while swimming, running, or exercising without ear canal obstruction.

Designed for swimmers and active users who need reliable audio in and out of the water, these open-ear, bone conduction headphones let you keep environmental awareness while enjoying music. The unit switches between Bluetooth and an internal MP3 mode for underwater use, and the 32GB memory stores thousands of tracks. Lightweight and rated IP68, they’re built to tolerate full submersion, sweat, and rain while offering up to eight hours of playback per charge.

How do these headphones work underwater?

The GREYOLK headphones use a built-in MP3 player and bone conduction transducers so you can hear audio without relying on a Bluetooth link while submerged. Because Bluetooth signal does not pass well underwater, switching to MP3 mode lets the internal memory play tracks directly.

• Double-click the power button to toggle Bluetooth and MP3 modes.
• 32GB internal storage holds roughly 6,000 songs across MP3, WMA, WAV, APE, FLAC formats.
• IP68 rating permits full submersion, suitable for pool and open-water sessions.
• Magnetic charging cable also enables USB access to the internal disk for easy file transfer.

Will the Bluetooth 5.4 and battery last during workouts?

Bluetooth 5.4 provides a stable wireless connection up to about 10 meters when used out of the water, offering improved interference resistance over older chips. The integrated 150mAh battery charges in roughly 1.5 hours and delivers up to 8 hours of continuous playback or talk time on a single charge.

• Bluetooth 5.4 for stronger, more stable connections on land.
• About 8 hours playback from a full 1.5-hour charge.
• Compatible with iOS, Android, and most Bluetooth devices for on-deck listening.
• Magnetic cable simplifies charging and file access via computer.

Are these safe and comfortable for running and swimming?

The open-ear, bone conduction design sits outside the ear canal so you can remain aware of traffic, coaches, and other swimmers. At just 32 grams they’re lightweight, and their shape accommodates swim caps, goggles, and earplugs for dedicated aquatic use.

• Open-ear design preserves situational awareness during outdoor activities.
• Lightweight 32 g construction minimizes fatigue during long workouts.
• Works with swim caps, goggles, and earplugs; ideal for triathlon training.

What audio formats and storage options are supported?

• 32GB internal memory supports MP3, WMA, WAV, APE, FLAC formats.
• Stores up to approximately 6,000 songs depending on file size.
• Plug into a computer to drag-and-drop playlists or manage files.
