I have had the e18, e20, future, and now the F1. I must say out of all of these the best were the E20. Couldn’t believe they stopped making those.
I heard that the E20's were good for smaller ears, and they would have been a nice choice for a friend of mine.
I would like a pair of free earbuds if any are available that are not the e60 version, as I've bought two pair of enacfire e60 wireless earbuds and they both don't work and they cut out every other second and both earbuds have a hard time staying or being paired at the same time.
