Conclusion: Looks nice but has useless battery life, and pretty poor for being heard when in use, which kind of negates the purpose of it. Avoid. Unless you like buying things that don't work very well, and unless you like stress and frustration.
Pros: Small, Unobtrusive
Cons: Useless Battery Life, Nearly non-existent sound quality outdoors, Custom charging connector is not very robust, Doesn't pair very well
