Headphoneus Supremus
Nothing in the user manual about an ambient mode either and no app to download to change any settings or modes. Maybe that will come in the future, but right now function wise they are pretty basic.
They are quite isolating too, so maybe not for you, but personally I prefer the isolation.
I want the isolation but want easy access to the environment as well which is why I love the Earin M2. Stop the music and full ambient is on, start music and ambient is fully off. I would just like more battery life than the just over 3 hours the M2 supply but still want them to be as small as possible.
