My previous ones didnt have the frilly protective sheath, so it would occasionally rub/pull against my skin. La prima ricarica effettuata ha impiegato poco meno di 3 ore per terminare (lindicatore da rosso è diventato verde);11) il tasto di accensione delle cuffie ha due modalità di pressione: da spente bisogna tenere premuto un po il pulsante per farle accendere, mentre da accese basta premerlo una volta (senza tenere premuto) per attivare la modalità Superhuman Hearing. I have tiny features, but these are literally child size. Very easy plug & play. the shipping was on time and the quality is there and they look really nice. There were three of the ?shelves? were missing a sleeve. It was for me. All in all, it would have been okay for half the price but at this price I ended up returning it. Great Watch. Of course there is a loss in performance that only $300 can offer you.
