Sena 50S Universal Clamp Kit Black One Size — SOUND by Harman Kardon speakers & mic, improved voice clarity and reduced road noise

The Sena 50S Universal Clamp Kit with SOUND by Harman Kardon upgrades your motorcycle comms with redesigned speakers and a new microphone for clearer incoming and outgoing audio.

This clamp kit replaces the original 50S clamp and installs the SOUND BY Harman Kardon speakers and microphone, engineered with Harman Kardon to improve voice pickup and playback fidelity. It’s a direct-fit accessory for Sena 50S units and adds access to five adjustable audio equalizers via the Sena Motorcycles App. Original 50S owners who install this kit should update their device firmware and enable the SOUND BY Harman Kardon option in the app to access the new audio features.

How does the upgraded sound change riding communication?

The Harman Kardon speakers deliver clearer, more defined audio so intercom voices, navigation prompts, and music come through with greater transparency. The microphone’s redesigned sensor focuses on capturing rider speech while minimizing road noise, improving two-way clarity. You’ll notice improved intelligibility at cruising speeds and in varied wind conditions.

• Redesigned speakers tuned for motorcycle helmets
• Microphone sensor optimized for voice pickup
• Clearer incoming audio for intercom and media
• Reduced background noise during conversations

Will this clamp kit work with my existing Sena 50S device?

Yes — the clamp kit is compatible with all Sena 50S motorcycle communication devices and mounts in place of the original clamp. After physical installation, you must update your 50S firmware and enable the SOUND BY Harman Kardon speakers through the Sena Motorcycles App to unlock all audio options. The kit is supplied in a one-size clamp designed to fit typical helmet mount points used with the 50S.

• Direct replacement for original 50S clamp
• Requires firmware update via Sena app
• One-size clamp fits standard 50S mounting points
• Activation done through Sena Motorcycles App settings

What adjustable audio controls are available?

Once enabled, the SOUND BY Harman Kardon speakers provide access to five adjustable equalizer presets in the Sena Motorcycles App. These presets let you emphasize vocals, balance bass and treble, or choose a neutral profile for spoken comms. Adjustments can be saved to match helmet type, riding speed, and personal listening preference.

• Five distinct equalizer presets in the Sena app
• Profiles for voice clarity and music balance
• Quick switching while parked via the app
• Save custom settings per rider preference

How easy is it to install and maintain?

Installation follows the same clamp-mount steps as the original 50S clamp and requires only common tools; no soldering or advanced modifications are needed. After mounting, pair and update firmware through the Sena Motorcycles App to enable the Harman Kardon components. Routine maintenance is minimal: check connector fit and keep speaker mesh free of debris for best audio performance.

• Fits existing 50S mounting points without modification
• Simple app-driven firmware update required
• Low-maintenance: inspect connectors and speaker openings
• Compatible with helmet cleaning practices (avoid liquids on speaker mesh)

Who is this for: Riders who already own a Sena 50S and want improved audio fidelity for intercom calls, navigation prompts, and media playback will benefit from this upgrade. It’s ideal for commuters, touring riders, and groups that depend on clear voice communication at speed. If you value better sound and clearer outgoing voice pickup and are comfortable updating device firmware via the Sena Motorcycles App, this clamp kit provides a straightforward way to enhance your 50S setup.
