## Overview

Sena’s High Definition Speakers deliver a 50% boost in audio clarity and enhanced bass, designed specifically for Sena 20S EVO, 30K, 20S, and 50S headsets. Featuring a low-profile beveled shape to reduce ear chafing and updated firmware plus app EQ presets, these lightweight speakers fit seamlessly into helmet pockets, elevating both communication and music experiences for riders.

## Description

The new HD Speakers by Sena were designed to deliver crisp communication sound quality and a premium music listening experience. With a stunning increase in volume and bass boost, these all-new HD speakers will rock you! The speakers incorporate a low profile bevel, reducing potential ear-to-edge chafe, and as always, easily fit into existing helmet speaker pockets. Sena has also developed new firmware for the 30K, 20S EVO, and 20S, which will allow you to get the most out of the new HD Speakers. Additionally, your Sena device’s mobile app has been updated to enhance the output of the HD speakers, including new Audio EQ Presets. So be sure to take advantage of both of these updates in order to experience everything the new HD Speakers have to offer!

Review: Better than original factory for SENA More clear sound
Review: Sound is a bit better than stock, made better by enabling HD speakers in the Sena unit settings. Huge bonus is that they fit perfectly into the Shoei RF1400. The original 20S speakers do not fit without modification due to a protrusion on the speaker housing for the wire connection. In the box is just the speakers and two "loop" style sticky pads to mate up with the "hook" side on the speakers which worked great. Added some pics that I couldn't find in other reviews that might help someone else. No one cares to see a selfie of you in your helmet with a review of speakers! They want to see how they will install into their helmet.
