Since it just needs to rest on the cradle and there are no pins to line up the speaker can face in any direction making the charging cradle extremely easy to use. * I tested both with and without the low-cut filter switch engaged on the microphone and really never noticed any difference - I havent found any specification of exactly what frequency below which the signal is attenuated (any know?), but Ill likely just leave the filter switched on. I love these slippers, I have very wide feet and am a diabetic, I need to wear something on my feet most of the time and these fit any foot and my first pair were about 5 years old before they started to fall apart and even then it was the sole that was breaking the rest of the slippers were just fine. 5 to a size 8, theyre still pretty snug, but doable. Quality is ok but still aluminum, hopefully it will last. En conclusión estos audifonos no son para todos ya que depende mucho la anatomía de tu oido y como el silicon embona con el canal auditivo y puede llegar a ser muy molesto. They’re easy to install. I’m so glad I did! I also liked using these ear buds to listen in on my 4 year old through the Alexa app when she was supposed to be napping. Muy práctico, fácil de instalar
