Monster Open Ear BC300 Swimming Headphones, Open Ear Bone Conduction Headphones, Bluetooth 6.0 & 32GB MP3, IPX8 Waterproof Sport Earbuds with 10H Playtime (Black)

Q1: Can I stream music via Bluetooth when my head is fully underwater while swimming?
A: No Bluetooth radio waves cannot transmit stably through water, which is a universal physical limitation for all Bluetooth audio devices. For uninterrupted underwater listening, simply switch to the built-in 32GB MP3 mode. It holds up to 8, 000 songs and works completely offline, so you can enjoy steady playback during every lap, flip turn, and open water swim without relying on your phone.
Q2: Can I organize music into separate folders/playlists in MP3 mode? Does shuffle mode repeat the same songs?
A: Yes, you can sort your music, audiobooks, and podcasts into separate folders when transferring files via computer, and easily switch between folders directly on the headphones. The shuffle mode is optimized to cycle through your full music library without frequent repeats, and the device remembers your last playback position you wont have to start over from the first track every time you turn the headphones on.
Q3: What kind of charging cable does this swimming headphone use? Will the charging contacts rust after regular pool use?
A: These headphones come with a magnetic charging cable for easy, secure attachment and a full charge in about 2 hours. The charging contacts are made of corrosion-resistant material, paired with full IPX8 waterproof protection, so they will not rust or corrode from regular pool or saltwater use. The magnetic design also avoids wear from repeated plugging and unplugging compared to standard USB ports.
Q4: I have a smaller head. Will these bone conduction headphones stay securely in place during lap swimming and flip turns?
A: Absolutely. The headphones are built with a flexible, adjustable memory frame that can be gently reshaped to fit different head sizes snugly. The soft silicone body stays stable during flip turns, freestyle and other high-movement strokes, and pairs seamlessly with swim caps and goggles without slipping or causing pressure discomfort over long workouts.
Q5: Is the volume loud enough underwater? Can I listen to audiobooks and podcasts clearly while swimming?
A: Yes, the audio is tuned specifically for underwater bone conduction performance, with enhanced vocal clarity and balanced sound when submerged. For audiobooks and podcasts, the spoken-word frequency range is optimized so you can follow narration easily. The device also saves your playback progress, so you can pick up right where you left off. For the best experience, use the included earplugs to reduce bubble noise and boost perceived volume.
