DIVEVOLK x Ocean Reef Audio Dive Kits: Add Real Sound to Every Dive

Watch almost any amateur dive clip and you will notice the same thing within seconds: it is silent. The reef is stunning, the fish are everywhere, and yet the footage feels strangely lifeless because the one sense that makes a dive feel alive in person—sound—has been stripped out. Worse, while you are down there, you cannot easily talk to your buddy, your student, or the crew at the surface. For decades, underwater storytelling and underwater teaching have both been held back by the same wall: water muffles voices, and sealed housings cut the microphone out of the equation.

DIVEVOLK and Ocean Reef set out to fix that wall with a single, integrated solution. By pairing DIVEVOLK's SeaLink underwater signal transmitter with Ocean Reef's Neptune III full face mask and a purpose-built wireless microphone transmitter, the two brands created three ready-to-dive kits that finally let you record clean underwater voice, narrate as you film, and—on the higher tiers—talk to other divers in real time.

Why sound is the missing layer in underwater content

Underwater video has improved dramatically. Phones in a quality housing now shoot footage that rivals dedicated cameras, and DIVEVOLK's full-touchscreen approach means you can focus, switch modes, and review clips without surfacing. But video is only half of storytelling. A documentary, a tutorial, a dive log, or a livestream all lean on the human voice to explain what the viewer is seeing.

The problem is physical. A regular dive regulator fills your mouth, so you cannot speak clearly. A standard housing seals the phone away from any usable microphone. The result is the familiar "silent dive video" that needs music or a voiceover added later on land—long after the moment, the emotion, and the detail are gone.

The fix is to capture the voice at the source: inside a full face mask that leaves your mouth free to talk, with a microphone wired into the mask and a transmitter that carries that audio straight to your phone. That is exactly the chain this DIVEVOLK × Ocean Reef system builds.

How the DIVEVOLK × Ocean Reef system works

The system connects three jobs into one signal path:

• The Ocean Reef Neptune III full face mask keeps your whole face dry and your mouth free, so you can breathe and speak naturally underwater.
• An Ocean Reef voice unit (Alpha Pro X-Divers or GSM Cube3 R2) sits in the mask and picks up your voice—and, on the advanced unit, enables two-way diver-to-diver talk.
• The DIVEVOLK Wireless Microphone Transmitter (WMT) plugs into the mask's voice port on one end and streams the audio over Bluetooth to your phone on the other, so your dive footage records with clean, real-time narration instead of silence.
• The DIVEVOLK SeaLink transmitter carries your phone's signal up through the water, so a livestream, a video call, or a real-time feed can reach the surface and your audience.

The DIVEVOLK Wireless Microphone Transmitter is the small part that does the quiet heavy lifting. It is a dedicated underwater audio system built for diving: one end connects to the voice port of a full face mask like Ocean Reef's, and the other end transmits your voice wirelessly to your phone over Bluetooth. It supports lossless underwater voice capture and real-time recording, so the audio is locked to the footage as it happens—no syncing voiceovers later. Built from durable plastic and weighing just 250 g, it stays light and portable across every kind of dive, from teaching sessions to expedition documentation.

The three kits at a glance

DIVEVOLK and Ocean Reef bundled the hardware into three tiers. Every kit includes the SeaLink transmitter, the DIVEVOLK Wireless Microphone Transmitter, an Ocean Reef Neptune III mask, an Ocean Reef voice unit, and a backpack. The difference between them comes down to one thing: how much you want to talk underwater.

Basic Kit — give your dive footage its voice back

The Basic Kit is built for the creator whose first priority is clean narrated video. It pairs the SeaLink transmitter and the DIVEVOLK Wireless Microphone Transmitter with the Neptune III full face mask and the Alpha Pro X-Divers Underwater Unit 2.0, plus a backpack to carry it all. The Alpha Pro unit captures your voice underwater for recording, so you can describe a species, walk through a skill, or react to the moment while the camera rolls. What it does not do is two-way conversation—it is a capture-and-record system, not an intercom.

If you shoot solo tutorials, dive logs, or narrated reef tours and you want the audio captured live instead of dubbed in later, the Basic Kit covers it at the lowest entry point of the three. Official retail is $5,499 (€4,999).

Advanced Kit — add real two-way conversation

The Advanced Kit keeps everything in the Basic Kit but swaps the voice unit for the GSM Cube3 R2. That single change unlocks a big capability: in addition to capturing your voice for recording, the GSM Cube3 R2 supports two-way voice intercom between divers. You can talk to a buddy, coach a student through a skill in real time, or coordinate a shot with a teammate—without hand signals or a slate.

This is the tier for dive instructors, guided-tour leaders, and content teams who need to communicate while they work. You get narrated recording for your footage and live diver-to-diver talk in the same setup. Official retail is $5,799 (€5,599).

Almighty Kit — the complete package

The Almighty Kit is the top tier. It carries the SeaLink transmitter, the DIVEVOLK Wireless Microphone Transmitter, the GSM Cube3 R2 two-way voice unit, a backpack, and the Neptune III mask package—the upgraded mask configuration rather than the standalone mask used in the lower kits. It is the choice for professionals who want every capability in one box: live narrated recording, two-way intercom, and the more complete mask setup.

If you produce underwater films, run a teaching operation, or document expeditions where communication and audio quality are not optional, the Almighty Kit is the no-compromise option. Official retail is $6,699 (€6,199).

What's inside, component by component

SeaLink underwater signal transmitter

SeaLink is DIVEVOLK's underwater signal transmitter—the piece that gets your phone's feed up through the water so a livestream, a video call, or a real-time broadcast can actually reach the surface. It is built on the same platform as the SeaTouch 4 Max Plus housing, which is why its phone compatibility matches that housing exactly. Sold on its own, SeaLink carries an official retail price of $2,999 (€3,199). You can explore it and the rest of the range in the SeaLink transmitter collection.

DIVEVOLK Wireless Microphone Transmitter (WMT)

The WMT is the audio bridge described above: it connects an Ocean Reef–style full face mask to your phone, capturing lossless underwater voice and recording it in real time. At 250 g and built for repeated dive use, it is the component that turns "silent dive video" into narrated footage. Sold separately, it retails for $319 (€320).

Ocean Reef Neptune III full face mask

The Neptune III is an integrated full face dive mask that delivers smooth, natural breathing while leaving your mouth free to speak—the foundation that makes underwater voice possible. It comes in three colors (black, white, and blue) and two sizes (S/M and M/L), and its regulator connection is available in both DIN and INT (Yoke) fittings, so it matches common tank setups. As a standalone mask it retails for $1,400 (€999).

The two voice units: Alpha Pro vs. GSM Cube3 R2

The voice unit is the single choice that separates the three kits, so it is worth understanding clearly.

• Alpha Pro X-Divers Underwater Unit 2.0 — $850 (€636): captures your voice underwater for recording. It is a one-way capture system: great for narration and documentation, but it does not transmit a conversation back to another diver.
• GSM Cube3 R2 — $1,200 (€1,170): does everything the Alpha Pro does and adds full two-way voice intercom, so divers can actually talk to each other underwater.

Which kit is right for you?

• Choose the Basic Kit if you mostly shoot solo and your goal is narrated, recorded audio on your footage.
• Choose the Advanced Kit if you teach, guide, or film as a team and you need real two-way conversation underwater.
• Choose the Almighty Kit if you want every capability plus the upgraded Neptune III mask package in a single professional bundle.

Because each kit shares the same backbone—SeaLink, the wireless microphone transmitter, a Neptune III mask, and a backpack—you are never giving up the core experience by choosing a lower tier. You are simply deciding how much you want to talk, and to whom.

Compatibility and regional versions

SeaLink ships in region-specific versions to match local wireless standards: EU (which also covers the Asia region), Australia, Japan, and US editions. If you are unsure which version fits your area, confirm with DIVEVOLK before ordering rather than guessing.

For phone compatibility, SeaLink follows the SeaTouch 4 Max Plus housing exactly, so any phone model that fits that housing works here too. Check your specific model on DIVEVOLK's technical support and compatibility page before you buy, and reach out through contact us if you need help choosing a regional version or a kit tier.

Hear your next dive, don't just watch it

For years, the gap between what a dive feels like and what the footage shows came down to a missing soundtrack—your own voice. The DIVEVOLK × Ocean Reef kits close that gap by building a clean audio path from a full face mask straight to your phone, then carrying the signal up through the water with SeaLink. Whether you are recording a narrated reef tour, coaching a student in real time, or producing a full underwater documentary, there is a kit tuned to exactly how much you need to say. Browse the SeaLink transmitter and the wider underwater phone housing range to build the setup that finally gives your dives a voice.
