OPN Sound Swym+ Black Bone Conduction Headphones

OPN Sound Swym Plus — Waterproof Bone Conduction Headphones for Swimming and Sport

OPN Sound Swym Plus bone conduction headphones are built for athletes who refuse to choose between music and movement. The headset rests outside the ears and sends sound through vibrations along the cheekbones, leaving ear canals open so the user can hear traffic or a coach's call. Fully sealed to IP68 standards, the Swym Plus allows submersion in up to 1.5 meters of water.

Standout Features: 32 GB Onboard Storage and Dual Playback Modes

What separates this model from typical open-ear sport headsets is the integrated 32 GB MP3 player. Users can drag and drop MP3, WAV, WMA, APE, FLAC, or Apple Music files directly onto the device and leave the phone at home during pool laps. Bluetooth 5.3 handles wireless streaming when a phone is nearby, and the included earplugs block splash noise so the bone-conduction signal cuts through underwater.

Technical Specifications — Battery, Drivers, and Waterproofing

The technical profile targets endurance athletes who log long training blocks. A 150 mAh lithium-ion cell delivers up to 7 hours of playtime per charge, with a full top-up taking roughly 2 hours. Bone conduction drivers cover a 20 Hz – 20 kHz frequency range, and the silicone-coated wraparound frame weighs 34 g for a stable fit. A built-in microphone handles hands-free calls (no active noise cancelling), and the box ships with a USB charging cable, carrying bag, earplugs, USB adapter, and manual.

• Construction: Bone conduction — open-ear fit that keeps ear canals free for ambient sound.
• Bluetooth Version: 5.3 — stable wireless streaming with low power draw.
• Frequency Range: 20 Hz – 20 kHz — full-range response from the bone conduction drivers.
• Play Time: 7 hours per charge from the 150 mAh lithium-ion cell.
• Waterproofing: IP68, 1.5 m depth — sealed for swimming and pool training.

Who Is It For — Swimmers, Triathletes, and Outdoor Runners

The Swym Plus is the right choice for swimmers and triathletes who need waterproof audio without the bulk of a separate MP3 player. Open-ear commuters, cyclists, and runners benefit from the situational awareness that bone conduction provides, while the 32 GB storage suits users who want a phone-free pool session. Anyone training in rain, at the lake, or on the road will appreciate the IP68 sealing and the 7-hour battery.
