318 series helmet is very comfortable and light weight. I keep listening to music and attend calls on the way to office. Initially was the voice was not clear, but once I placed the speaker near the soft bone near the ears, the audio quality improved and it is good now. Battery is really good. I have done 3 hours of ride and still the battery is nearly 70%. Like this new concept of having Bluetooth speakers in the helmet itself.

Riding with the zakpro LED series helmet was interesting. Initially I was not aware of this concept of having indicators in helmet itself. But I got one and tested. It is extremely useful during dark lights. I normally take rides early in the morning where I only use one front light for night vision. I often have trouble in traffic spotting me from behind while riding. This helmet has both front and back indicators and helped me during early in the morning. Also this helmet is very light weight. I will recommend this particularly for people who ride early in the morning or late in the evening.
