Hi all, I'm debating myself over the purchase of a pair of headphones. I can't decide between B&O H6 or Beats Studio, wired or wireless. On the one hand I think that being dependent on batteries just to use your headphones could be an annoyance and a little bit of a "slavery". I plan to use these headphones a lot, so at 6-10 hours of battery life for the wired version and 12 for the wireless, I will have to be constantly changing/charging batteries. B&O H6 does not have this problem. On the other hand, I realise that batteries give a much better noise isolation with the Beats than with the B&O. This is important, as these headphones will be used mostly at the (noisy) office. I have tested the B&O and they have a good passive noise isolation, but the Beats ANC seems much more effective. Do you guys have any thoughts about this? Thank you!
