Accessories bluetooth speaker for audio



I'm thinking about buying a bluetooth headset

what headset type or model would you recommend when my need is to listen to podcasts using the headset? so I know it must have a good battery life of say 8 hours or so

the podcasts have clear voice and minor music. what should I get and what I shouldn't definitely get?

I have the desire.

oh yeah: I have a pretty big head and it would be nice for the headset to be comfortable when wearing it for hours
