I’ve been asked by many motorcycle riders especially sportbike riders as to the question of what are the best full face helmet speakers. I can tell you of my experience and what I have discovered for me the best product out there. The speakers I’ve had great luck with are speakers that are specifically made for most fullface helmets by IASUS CONCEPTS INC.
XSOUND 2 (XS2) HELMET SPEAKERS
IASUS XSound 2 Helmet Speakers are tuned specifically to provide all of the bass and treble you need to fully enjoy your music, whether you occupy speedways or mountain slopes. The design maintains an ultra-slim 0.5” thick speaker that fits comfortably inside most full-faced helmets, making them an ideal in-helmet audio system for motorcycles, snowboarding, skiing, paragliding, snowmobiling, and other helmet sports.
This company specializes in many types of communication specialties as military, law-enforcement and racing. Plus, my experience includes using the xs2 speakers in my Shark RS2 and RACER R-PRO helmets with great success. As to installation the speakers come with velcro attachments. In my own installation in my RS2 required me to cut out a small ear piece section out of my helmet liner near the ears as to get enough head clearance for my ears. I removed the liner and cut out a section of liner and ran the speaker wires along the inside of helmet securing them with black electrical tape. Then as to secure the wiring from being jerked out by helmet removal, I threaded a small wire tie through the helmet liner around the wiring to better secure the wire. I also have found through experience to add more heavy duty velcro tape to the speakers as to make them less likely to pull loose from the helmet.
Now to the question of volume, my bike is fairly quite with factory mufflers “Hayabusa” and a previous bike Bandit 1250 with slip ons. These speakers also have a portable amp that can be used along with these speakers and it really boosts the volume as to enhance the ability to hear my music even at very high speeds. Plus, cost is very affordable and with a one year limited warranty. These are great products and I would highly recommend them. You’ll have to buy them through a reseller as the company provides a list of those companies that sell their products here in the states as well as abroad.
