I was actually shocked about that, they seemed worthy, but not when everyone was either hanging upon me, or kept saying I cant hear you. We always buy these when we visit the States, but we can now buy these in UK via Amazon My wife says that they so comfortable and wear them all the time *I posted the initial review 5 month ago when I purchased my baby seal. So far the battery is fully charged and working great. I only need it to hold three pair but it could hold 6 if I fully extend it. Update - Nach dem 3ten Ladezyklus wird der linke Ohrhörer nur noch 88 % geladen ( siehe Foto ) . As well, I noticed that when I had my Windows 10 laptop and Samsung phone connected, audio playback from a video on my laptop was choppy. The Caps Lock light wasnt working when received, then it worked for a few days, then stopped working again. I think they are just a deterrent. Muy buena calidad, duracion de bateria hasta 5 horas de uso continuo, la calidad del audio es malo inclusive al encender/apagar el sonido de bienvenida la calidad es muy baja, usando alguna aplicación para modificar la calidad del audio mejora bastante, ademas me hubiera gustado que incluyeran un estuche ya que traerlos en la mochila se activan constantemente y cuando necesito usarlos la bateria esta gastada.
