I bought it together with a new helmet. For 4 months, it was perfect. Then it started distorting the sound, it couldn't be heard. I took it back to where I bought it and they told me it was the headphones. They changed the headphones for me, but as soon as I left the store, in 5 minutes, it was the same again. Then they changed the base for me, and in the end, they only didn't change the unit. I take it back to them and they tell me it might be the phone's fault.
But is it possible? It was working on the same phone. I see myself crying over the 140€

If you have a machine without this, you don't know what you're missing!
From quality to effectiveness to intensity to connectivity,
in all aspects 5 stars.
One of my best purchases and useful

Good pair with good pairing and good sound. I have a slight delay in sound transmission between the two devices. I don't know if it's my problem or if someone else has noticed it, but they ultimately do their job very well. The headphones are heavy compared to other intercom headphones, but that's not an issue. Overall, satisfactory.
