The BH51M NSO Urban is fantastic

I love the BH51M NSO, the sound is really good ! Much better compared to my other LIVALL helmet LIVALL BH 60 SE and the LIVALL MT1 NEO
Unfortunately I had some technical problems with the bluetooth connection, looks like I got a defect helmet.
However, contacted the support, will return the helmet and they will send me a new BH51M NSO.

As good as the first one

This is my second helmet, I needed another one at another location for also enjoying the pleasure to listen my favorite radio stations while riding.

Fantastic sound, quite comfortable (but size too small), BR80 remote battery was dead

I'm usually size Medium but I had to use the helmet at the absolute maximum size which is only just acceptable. The stereo sound is great and I do not have to use more than @80% volume to drown noisy traffic (low enough to be aware of my surroundings) It was easy to use the IOS APP to set it up. The BR80 remote control was a major challenge. I tried to update the Helmet software, BT connect and un-connect, restarted e.t.c... in the end I changed the battery and it connected almost instantly. Its buttons are difficult to operate with thick Winter gloves! They are fine without. The helmet feels quite lightweight. The loud voice prompts are great. It is a bit strange that the minimum operating temperature is 0 degrees Centigrade. I intend to test it down to -20 for @45 minutes. I hope the battery doesn't die like my I-Phone after 10 minutes, if exposed to the cold!!! (I bike to work all year, literally)
