Reviews
The EARIN M-1 are minute, in the ear speakers. They take a little fiddling to get into place but once right feel comfortable. The M-1 are minimalistic ear buds, no microphone or controls. They are actually quite affordable too.
The downside is that they you don't get more than 3 hours out of a full charge and when others on the market can hold around 5 hours its a little dissapointing. There is also a bit of an intermittancy with the the connection of the blue tooth otherwise reliable. These are simple and straightforward wireless ear buds. I believe there are more to come from EARIN so will look forward to triying the upgraded model.
