Sena SMH-A0302 Helmet Clamp Kit for SMH10 - Black with Boom & Wired Microphones, Speakers

The Sena SMH-A0302 is a removable clamp kit that equips an extra helmet to use with a Sena SMH10 Bluetooth headset, including both a boom and a wired microphone for flexible installs.

Designed as an accessory for the Sena SMH10 (headset sold separately), the SMH-A0302 kit gives you everything needed to mount a full communication setup on a second helmet. It’s built for riders who switch headgear or want a spare installation: speakers with Velcro pads, a detachable boom mic, an alternate soft wired mic, a clamp bracket and adhesive mount, mounting hardware with an Allen wrench, and a 3.5 mm auxiliary cable for wired audio input.

How simple is installing the SMH-A0302 on another helmet?

Installation is straightforward for most helmet shells and liners. The kit provides both a slide-in clamp bracket for under the liner and a double-sided adhesive mount to suit different helmet interiors and rider preferences.

• Includes clamp bracket that slides between shell and liner with Allen bolts and wrench.
• Double-sided adhesive pad for helmets where a clamp won’t fit or for a cleaner look.
• Velcro speaker pads for quick positioning and removal of speakers.
• Detachable cables let you route wiring neatly and swap microphone types.

Which microphone option should I use—boom or wired?

The kit contains both a flexible boom microphone and a soft wired microphone so you can choose based on helmet style and noise environment. Use the boom mic for open-face setups or when you need the mic positioned closer to your mouth; choose the soft wired mic for full-face helmets where internal mounting is preferred.

• Boom mic: detachable, directional, ideal for open-face or modular helmets.
• Soft wired mic: low-profile and flexible for under-liner mounting in full-face helmets.
• Both mics are removable for storage or swapping between helmets.
• Quick-connect wiring makes transfer between helmets fast when paired with an SMH10 unit.

What functions does the SMH-A0302 support when used with an SMH10 headset?

When paired with the SMH10 module (sold separately), the clamp kit enables full Bluetooth hands-free features: phone calls, stereo music, and long-range intercom with other riders. The hardware in this kit simply provides the physical interface to use those SMH10 features on additional helmets.

• Compatible with SMH10 Bluetooth v2.1 headset functions (phone, A2DP music, intercom).
• Includes 3.5 mm aux cable to connect wired audio sources when needed.
• Speaker mounts preserve stereo sound from the SMH10’s advanced audio processing.
• Retains separate volume profiles and jog-dial control through the SMH10 unit.

Who this is for: The SMH-A0302 clamp kit is aimed at riders who already own a Sena SMH10 and need a repeatable, tidy installation for a second helmet or a quick way to transfer the SMH10 between helmets. It’s ideal for couples who share bikes, riders with multiple helmet types (full-face and modular), or anyone wanting a spare setup for convenience without buying a second SMH10 unit.
