No dryer/charger, as this model while very advanced is very reasonable $. The TV connector in my opinion is a must, but must be ordered, not apparently an in stock item, so check. My loss is great so battery life for me is 5 days if I switch the batteries at night, left to right. If not 4 days. You have to open the battery door every night or whenever you take them off anyway so switching isn’t a problem. I noticed that the right side always went dead first so got the idea to switch back and forth. Your old ones shut off with a push, was handy when wanting to mute, doing loud work, etc. The Ks9 does have a mute, but you may need to ask for it, it is activated by a long push on either lower button.
