I can't confirm that. no improvement on listening on an iPhone. listening to music via Bluetooth over Mac even got worse. also they removed a feature. now I can't stay connected to my phone and notebook at the same time. I'm very upset with this firmware upgrade or should I say downgrade? 

My impressions:
• Still cuts out, hard to say if it is less than before. Depends to much on the environment and what is in the environment at _that_ time.
• Takes longer to power on and establish bluetooth connection.
• It doesn't make the same sound feed back, just one beep now?
• Used them a few days ago and the battery just ran out, no audio feedback before as it was earlier. (Used with my Mac, so no battery indicator over bluetooth there).
• They seem to hang less often on power on, but they can "crash" during use (happened once after the update).
• I have to disconnect and try to manually connect to get them over from iPhone to Mac and vice versa. VERY annoying. Wasn't like that before.
• Sound quality is the same I think, but ANC works better, especially walking outside. Less clicks when I walk, so now I can for the first time use ANC while walking, even in light wind. So this is a good thing at least! 

Yes, agreed that the ANC behaves better for the walking noise - it's still there, but much less.

I also noticed that the headphones pick up very little wind-noise compared to the ones I've tried in the past (most brands except Bose, they suck)

Note that I'm listening now with my iPhone on my desk with a thick fleece, Kindle, rucksack full of junk and MacBook Pro and no cut outs...

However, if I sit on my iPhone then the signal is lost totally 😮

OK, after a weekend of testing and then today with the same jeans, it's actually no better, no change at all in fact.

So having the iPhone in my jeans pocket - not a particularly tight fit - and it cuts-out all the time. If I wear some baggy flight or combat trousers then it's fine.

I can only guess that the antenna in the headphones is incredibly weak and as soon as the signal strength drops below 100% it cannot cope.

I tried with a Sennheiser BT transmitter, using Apt-X, and it was the same experience.

However, I do like the headhones very much otherwise and I was lucky to get them for a good price, so I'm going to keep them in the hope that B&0 come up with something...

I have had my H8's since April this year and I have had drop out issues with my old Moto G phone all the time it was unusable. I got myself an iPod Nano and it was fine, worked flawlessly. The ionly issue I had was they would disconect once after around half an hour of use, I simply switched them off and back on again and they worked perfectly. No signal loss, unless i put my hand in my pocket where the iPod was located. I can have them in any pocket, tight or loose and no dropouts at all.

I then got myslef an iPhone 6s Plus and all worked perfectly. Same disconect issue as with iPod, but no dropouts and can have the iPhone anywhere I want on me.

After software upgrade they now switch to bluetooth much faster and litererally straight away. Still the same disconection issue, but I can#t simply turn them off and on for re-connection as I used to, I now have to go into the phone settings and manually re-connect and also I find if i turn on my H*'s first into BT mode before enabling BT on my iPhone they don't auto connect, I have to make sure Ii turn on BT on the iPhone brefore switching on BT on the H8's, otherwise they don't connect unless i manually connect on the iPhone.

I am happy with them and they are extremely comfortable now as I have broken them in, they were a little snug when i first got them, but like a good pair of shoes they needed breaking in to make them wearable all day.

I get the impression that behaviour varies from headphone to headphone, but for sure they are supremely comfortable!

I wrote to B&O customer services and although it took a while, I got the following response:

"We are aware of a Bluetooth issue on a small amount of our BeoPlay H8 headphones.
Until now we have not been able to locate the entire amount of headphones with this issue.
We have our technical team working on a solution to this issue at the moment, but I can not promise you when a solution will be available.

So far we have had great experiences from replacing the BeoPlay H8 models with Bluetooth issues, and therefore I would like to offer you the same. However I can not promise you that the replacement pair of BeoPlay H8 will not have the same problem."

I have now created a ticket to return the items - they will collect next week and, I assume, send me a replacement pair. I guess the down-side is that I'll be without the headphones for some days or weeks...

Will keep you all informed, but seems to me that here B&O have been open and correct in how they've responded; which is what I'd expect from a premium brand.

Would it be possible to use H7 ear pads on the H8?

Thanks Martin 

I have a few other questions, could some more experienced users please confirm whether the below is normal and if there are any developments or fixes. 

1- Why the headphones don't automatically connect when both my Bluetooth is turned on, on my phone and my headphones. 

2- The sound output is distinctly different and muted when ANC is on and there is more white noise.

3- Why audio and video playback has a significant lip sync delay. 

4- Would B&O be kind enough to give me an in line volume and playback cable - because the lip sync is so disastrous. Has anybody been able to get one?

Many thanks and Merry Christmas!
