I managed to break the sync between pack A and the receiver. Is there a way to re-sync the units?

Yes. Here is how: 1. Power off the receiver and power on the CHA transmitter (the one that does not sync with the receiver); 2. Hold and press the power button and both volume buttons in the transmitter until the LCD starts to flash; 3. Power on the receiver, wait for a few seconds, power off the CHA transmitter. 4. When you power on the CHA transmitter again, it is paired with the receiver again. Please feel free to contact Hotec customer support if you need further assistance. We can be contacted at Support@sz-tecson.com. Thank you.

Do you make these where the receiver uses aa batteries?? we need to go 6-8 hours and can't stop to usb recharge.

The box receiver is powered by an AC adapter and the two transmitters are powered by rechargeable battery. The transmitters work for about 6 hours at a full charge. Thank you.

I am only getting about three hours out of a full charge. Is anyone really getting six hours like the claim? This is all four I have?

I have never used it for more than 2 hours at a time, but can use it for 2 two hour sessions before recharging.

Can I connect this to my laptop?

Yes, but the connection might be a little bit complicated. Please contact Hotec customer service for more assistance.
