Hi all, recently updated my iPhone 6 to iOS10.3 and I've been experiencing constant dropouts with my HA-2, requiring it to be switched input or turned off and on to reconnect. Changed cables, turned off cellular data but still doing the same. I ran it with a MacBook Pro and had no problem so I reckon it must be phone related. Has anyone experienced this and are there any suggestions that might cure this? I love my HA2 but it's doing my head in at the moment!!

My HA-2SE did the same thing too
After upgrading my 7 plus to 10.3, often the dac amp drops the analog signal from the 3.5mm jack while still being fed digital signal from the phone, which I have to replug or restart the device for it to work again. I don't know how to solve this, since there's no app that "allow" software update to fix the bug to the HA-2SE itself
This is starting to be a headache, is this a software problem with iOS 10.3 or hardware issue with the HA-2SE?

Think it's most definitely an iOS issue - works great with a Mac. I've contacted oppo so I'm waiting to hear from them. Hopefully Apple will be made aware of the issue.

Bumping this to see if anyone else has had this experience.  It will certainly keep me from moving to 10.3, especially since uninstalling it appears to be a major challenge, as 10.3 alters iOS's file system.

Just spitballing here.  Do any of you have the old CCK?  (The new USB-3 CCK doesn't seem to get along with the HA-2 at all.) What happens if you use that as an intermediary between the iPhone and the Oppo (switching the input to the B port)?  I tested this with 10.2 and it did work.  I'm just wondering if it might work with 10.3 and clear up the problem.  
 
For reasons I think you'll understand, at this time I am not willing to install 10.3 and try for myself.

This issue, according to the OP, happens even with airplane mode on, so this is probably not related.
 
But. There is a problem that occurred before 10.3, that made the HA-2 (and SE) reboot when you got to a low cell phone coverage area. I don't want to double post, but if anyone is experiencing that problem, the reply I got from Oppo regarding this can be found @ http://www.head-fi.org/t/755879/oppo-ha-2-portable-headphone-amplifier-dac-discussion-thread/4275#post_13399059

Yes, you have posted repeatedly about your issue. If you check my posts on that thread, they indicate that I have not experienced it. But your problem is not the one that concerns me. I'm trying to decide whether to update to iOS 10.3

this is definitely a different issue.  This is what i sent to Oppo:
 
  I was having drop outs before the iOS 10.3 update, however they were in a different form.  The difference between them:
 
Before update: music would stop coming through the headphones. The music would also pause on the iphone app as well. I could not press play again until I had unplugged the cable from the oppo.
 
After update (to 10.3): music stops coming through the headphones, however the app (Apple Music) carries on playing (albeit you cannot hear it). Once you unplug the cable the music app will pause (as it should do on an iphone once there is no headphone/device detected), then upon plugging the cable back in again you can press play and music will once again be heard.
 
In both instances you can either unplug and plug the cable, or just switch off and on the Oppo, they both have the same effect.

Oppo confirmed that they'd had another report of the same thing (on an iPhone 6 (mines's a 6s)).
