The 10S, and mount comes suitable for speakers and earbuds. Speaker volume is great even when wearing earplugs. The FM radio is soso, but it may ber the station I was listening to, but radio function is rarely used.
Works well with GPS, Phone and SR10 for UHF Comms. no-one has realised that the UHF is being used on a bike.
The 30S has great battery life, and can be charged on the go. You can plug in external audio. The unit will work in an SMH10 mount, SMH10 will work in the 10S mount. 30S speakes are good quality, but may need a bit of persuaion to sit deep enough to not press on the ears. (in the Shark flip front anyway)
