## Overview

## 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: Fit perfect into Shoei RF1400 unlike stock 20S speakers. - 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.
Review: Louder then what came with it. - I ride with a 1% club. We ride often, we ride tight and we ride fast. I use my 20s EVO almost everyday. As time has passed the original speakers started to fade. Then I could no longer hear my music while riding in a pack. So, I spent the money on these. Glad I did, because these damn things are amazing. I have to turn the music down now, while riding, because it’s too loud. Get buy for the money and would highly Recommend to anyone. Using a Shoei helmet RF-1200. Helmet is quite so I’m sure that adds to this but damn they are loud. Love it. Don’t guess, don’t worry, don’t keep looking for something better. If you have the Sena 20sEVO and a Shoei. But them now. It’s worth it
