Appears fast charging as advertised with 10W rated greater or equal to 72% efficiency. But it is well worth the work. My future video production would benefit a lot from this mic! So sadly since its after the thirty days the company said I have to go through amazon and amazons return policy says my return time limit ended on the first. They fit around my head ok which is considered a normal, non-peanut head:). I can?t wait to use these for not just my ps4 but my first gaming pc that I?m still waiting on. Excellent bass and sound clarity. Id give 3. I set up face unlock without glasses, but it works when I put on reading glasses, and also while wearing sun glasses (that one is amazing). Water-resistant, I use these for runs.
