Not super loud but can clearly hear my music and sat nav directions at 70mph whilst wearing earplugs. FM radio is good tho I find it can randomly go silent, needing a quick cycle from Radio to Bluetooth music and back, then it’s working again. Maybe a software bug? Fits excellent to the side of my flip-up Caberg Duke 2 helmet using the sprung clip. No issues except hiding the excess of cables as there was more than my last intercom had. Overall really happy with the Cardo Spirit HD. 2hrs listening to a mix of Bluetooth music and FM radio at 90-100% volume leaves 50% battery left. It audibly speaks and tells you battery life left when turning off. Connects easily to my iPhone 14 Pro Max. The Cardo app is really simple and easy to navigate. Would like more than 6 presets for FM Radio tho. Easy to find the 4 raised buttons, they feel like they need a fair amount of pressure to press, but with gloves on that equates to feeling precise and has a good click feedback.
