I had my H8 for some weeks now, and this is my experience:
Testing from inside my appartment:
I can listen to music with 9-10 m "free" distance from my phone (Iphone 6) without any dropouts with doors wide open. But if there is a wall between, i will get few dropouts sometimes if distance is 8-10 m.
(if stay within 5 m, signal passes through one massive 10 cm wall without dropouts)
Even if I put the phone under my sofa mattress (15 cm thick), there is no dropouts as long as I stay within the 5 m (safe zone) incl. a 10 cm massive stone wall in between.
I used the H8 on a short flight 2 times the past week. Each way listen around 1 hour straight without any dropouts. I even left my phone in flight seat and went to the lavatory wearing my H8 without any dropouts. Ok seat was 1st row (Ryan air flight though) and toilet just 2 m in front of seat, but still satisfying.
I have noticed, that when my Iphone is inside bluetooth settings (searching for bluetooth connetions) the H8 goes all crazy with dropouts, but leaving the settings all is fine again.
It is possible to cover my iphone with my body in some "unnormal ways" to force dropouts.
But this is just to test performance. Normally I wear my iphone in my front jeans pockets and it works perfect (both right and left pocket 😕)
When using the H8 I always keep my phone near me therefore the dropout symptoms is not something I experience in daily use.
Other comments:
The iphone quickly finds the H8 and connects to it. The materials and craftmanship of H8 is so nice.
The touch functions works very well (the volume control is however not so smoothly as the other touch functions. The active noise cancellation (ANC) was very good onboard airplane leaving most of noise out (much better than my old Sony in-ear with ANC). But if I use my H8 at home, I will use without ANC, as it gives a much better sound.
The only negative I have to say about H8 is that after 30-60 min use, my ears gets very warm (i want to take the H8 off and rub my ears).
At first when you try them, they feel very soft and comfortable, but after a while I feel a light pressure on my head and get the warm ears. Not terrible, but still something I notice and dislike.
I have before only used in-ear headphones and I am maybe not (yet) used to on-ear headphones.
But I recommend try them for minimum 30 minuttes in the B&O store.
My S/N is: 24501060 (purchased in Denmark).
