Colin Silvester 5 This is an excellent helmet for commuting in busy streets (I use it for a commute in/out of central Tokyo. Its fits comfortably (even with a skull cap) and connects directly to my smartphone (Android). The lighting works very well and with the connectivity to the smartphone, I can listen to music whilst riding. The speakers are in the base of the helmet and are located above the ears (not over them) so there is no interference with hearing ambient noise. Probably a bit too bulky for more serious road bike riding, but great for around town.
