Unsure why Alexa not on these as well. Plus delving into the earphones am not sure if all earphones are the same but the battery life of 5 to 6 hours would be annoying to me . It means every 5 or 6 hours you need to forget them for however long it takes to recharge. Would be no use to my missus as she has earphones in from getting up to going to bed! And no am not buying her 2 sets.
