This package deal includes six (6) of our Expand Mesh intercom headsets.
The Expand Mesh system is engineered to give you true full duplex, crystal clear, hands-free wireless intercom communications. The Expand Mesh is a truly wireless and hands-free headset design that sits comfortably and securely on your head, no matter how adventurous the activity.
Perfect for yacht and work-boat crews, drone operations, jobsites, film and stage crews, tour groups, and sailing instruction - any activity where hands-free, always-open communication beats push-to-talk. If your crew uses walkie-talkies, belt packs, or handhelds with earpiece cords for close-range coordination, these replace all of it.
Key features:
- Full duplex and hands-free - everyone talks and hears at once, no push-to-talk
- Mesh network with no master/slave pairing; an unlimited number of headsets can join
- Six separate Mesh channels, open or private
- Bluetooth 5.2 for phone calls, Siri, and music alongside the intercom
- Up to 10 hours of talk time; USB-C rechargeable
- Connects to 2-way ham, FRS, GMRS, or VHF radios with a separate adapter
- Secure behind-the-neck design - works with hats, glasses, and bushy hair, and cannot be knocked off
- Weatherproof for rain and spray
Shipping & lead times
Shipping & lead times
We're a small team of boaters and we pack orders within 1–5 business days (no weekend or holiday packing). You'll get an email with tracking as soon as a label goes on your box.
Specialty items — fire extinguishers (dangerous goods) and low-stock or built-to-order gear — can take longer; the product description will say so. On a tight timeline or meeting your boat somewhere specific? Contact us and we’ll work out the fastest way to get gear to you.
International orders ship DDU: local duties, taxes, and customs fees are the buyer’s responsibility. Full details in our shipping policy.

Replaces the walkie-talkies
Always-open conversation
Full duplex — everyone talks and hears at once, hands free. No push-to-talk button, no belt pack, no base station, no cords. Turn a headset on and it joins the group; walk out of range and it rejoins on its own when you come back.
Grows with the crew
The Mesh network has no master headset and no user cap on Open Mesh — add a unit any time and it connects automatically. Six separate channels keep neighboring crews from talking over each other, and Group Mesh makes a private session for up to 24.
If your crew coordinates with walkie-talkies, belt packs, or handhelds with earpiece cords, this is the upgrade: one behind-the-neck headset per person that cannot be knocked off, with Bluetooth 5.2 phone pairing and an adapter path to 2-way ham, FRS, GMRS, or VHF radios.

| 4-pack | 4 | Coach-and-trainees kit with storage case | $739 |
| 6-packyou are here | 6 | The whole crew talking out of one box | $1,075 |

Before you buy
How many do I need?
One per person talking. Two make a full conversation; there is no practical upper limit on Open Mesh, and additions join the group automatically without re-pairing anything.
Will these talk to Bosun, N2R, or TuffTalk M headsets?
Yes — every Sena Mesh headset we carry joins the same Open Mesh conversation: NautiTalk Bosun, NautiTalk N2R, and TuffTalk M included. Mix formats freely within Mesh; ask us if you are unsure what you own.
Can my existing Bluetooth headsets join?
Not directly — Bluetooth-only headsets like the 2Talk and SPH10 need a Bluetooth-to-Mesh adapter per headset to enter a Mesh conversation.
Is it waterproof?
Weatherproof — rain and spray are fine, submersion is not. If your crew works wet decks or you want a headset that survives going overboard, choose the NautiTalk Bosun: IPX7 rated, and it floats.
Can I connect a two-way radio?
Yes — ham, FRS, GMRS, and VHF handhelds connect through a separate adapter, so a Mesh crew can keep one foot on the radio net. Ask us about the right adapter for your radio before ordering.
What is the warranty?
Two-year manufacturer warranty against defects, handled through us as the dealer. Returns are 30 days from purchase, unused and in the original packaging.
