I got speakers called the xpro. I think it is supposed to fit the 800 dollar helmets but mine is very simular so it fits perfectly. Read the review of these speakers from amazon. The TORK Xpro helmet speakers have been making all the noise in the motorcycle helmet market. The Xpro’s have been branded with quotes such as “loudest speakers on the market” and “like having a concert hall in your helmet”. Take them for a test drive, we’re certain you’ll enjoy the ride even more!
