Sena C1

I decided to get this helmet as I wanted to listen to music whilst cycling and maintain a sense of my surroundings (having earphones in is just not a good idea, it's incredibly unsafe).The speakers are located on the strap, so they are positioned near your ears but not on or in them; surprisingly delivers satisfactory results.Connecting to my phone was very straightforward and I have also linked it to the app where you can quickly turn on the LED on the back of the helmet (this is another nice feature to have).I can't comment on the intercom feature as I don't have anyone else to cycle with who also owns this helmet, but if it's anything like their motorcycle intercoms, it's safe to say it should be decent.And finally, this helmet is very comfortable! Easy to adjust, has a soft chin cushion and is super lightweight.All in all, I'm very pleased with my purchase.

The right speaker stopped working after less than 4 months use

Rubbish don’t waste your money I bought 2 one broke sent it back that one broke got it replaced then that broke so all in I had 3 and they all broke They wouldn’t connect the Bluetooth and the plastic that holds the straps is really thin and flimsy. So sent them all back getting a refund
