The Open Ear Revolution: Why Choose Bone Conduction?

In 2025, the audio market is flooded with "open ear" options, but not all are created equal. While many competitors rely on "air conduction" (tiny speakers near the ear), the Greyolk V5Pro utilizes true Bone Conduction Technology. This bypasses the eardrum entirely, transmitting sound waves through the cheekbones directly to the inner ear.

Why does this matter?

• Hygiene: No drivers sit inside your ear canal, eliminating the risk of ear infections ("swimmer's ear") and fatigue from extended wear.
• Clarity: By bypassing the air, you get a direct audio experience that remains clear even in noisy environments or underwater.

IP68 Waterproof Mastery: Built for the Pool

Many wireless headsets claim to be "water-resistant" (IPX4 or IPX5), handling only light sweat or rain. The Greyolk V5Pro stands apart with a military-grade IP68 Waterproof Rating.

This isn't just for running in the rain; these headphones are engineered for full submersion. Whether you are swimming laps, snorkeling, or kayaking, the V5Pro is sealed against water, dust, and sweat.

• Depth Tested: Safe for continuous use underwater.
• Maintenance: Easily washable after a sweaty workout or a dip in saltwater (rinse with fresh water recommended).

Dual-Mode Freedom: Bluetooth 5.4 + 32GB MP3 Storage

One of the biggest content gaps in the open-ear market is the inability of Bluetooth to transmit through water. The Greyolk V5Pro solves this with its hybrid Dual-Mode Architecture:

1. Bluetooth 5.4 Mode (Land): Powered by the latest 2025 connectivity chip, enjoy stable, low-latency streaming from your phone (Spotify, Apple Music) while running or working. The 5.4 standard ensures minimal battery drain and "multipoint" stability.
2. MP3 Mode (Water): Bluetooth signals cut out underwater. The V5Pro features a massive 32GB Built-in Memory that stores up to 6,000 songs (MP3, WMA, WAV, FLAC). Leave your phone in the locker and listen to high-fidelity audio while you swim.

Safety & Situational Awareness: Hear the World

For outdoor enthusiasts, isolation is dangerous. The primary intent for choosing an Open Ear Wireless Headset is safety. The V5Pro allows you to enjoy podcasts and music while keeping your ear canals completely open to ambient sounds.

• Runners: Hear approaching traffic and cyclists.
• Office Workers: Listen to music without missing questions from colleagues.
• Parents: Keep an ear out for children while taking calls.

Comfort & Fit: The "Triple Threat" Test

A common complaint with ear hooks is discomfort when wearing accessories. We have designed the V5Pro with a slim, titanium alloy frame that passes the "Triple Threat" test. It fits comfortably alongside:

1. Glasses/Sunglasses
2. Swimming Goggles
3. Helmets or Caps

Weighing only 32 grams, the headset distributes weight evenly across the cheekbones, preventing the "pressure points" common with clamp-style earbuds.
