The last time I checked the battery in use is the usual 300 cycle rating. NO MAKER is giving us any more than that. You may find some with a few more minutes or run time but the "life" appears to alway be the usual 300 cycles. We can dismiss any idea of a long life battery and must plan ahead to replace the battery when it wears out.

"Easy to transfer to PC and play on TVs"

All the units I see at the stores are easy for me to do this. You may want to refine this requirement.

There are no great internal microphones. Be sure that any unit that makes the list have the external input.
