I'm pretty happy with OEM speaker on my '16 Deluxe. With a Half-helmet on, I can hear pretty good quality sound at 70+ mph with the volume at about 12-14. If I'm wearing my Full-face helmet, I used moldable in-ear buds. The Decibullz product certainly isn't for use on-stage (i.e., a musician), but for motorsports, IMO, more than adequate. (If I want hi-fidelity while traveling, I'll be in my cage.) And... at this price point, not a buzz kill if they break or get lost while on the road.
