  Thank you, guys. May be you could list some headphones that could be reasonable to listen to with the amp? The thing is my local store doesn't has wide range of headphones so I have to give them a list of models so they order them into the store where I could listen to. Or that could be a general guidance, the only constraints I can think of is that they should be under $500 amount. May be OPPO pm-3? I heard that they sounds really good with the amp...

Sure, Oppo PM3 is a great match and synergy with HA-2 and terrific value-for-money.

Apologies if this has already been covered. Is anyone experiencing interference using an iPhone 6S with the HA2?

What kinda interference are you talking about? From my experience, I didn't get any while using it with my iPhone.
 
Do explain more in details.

I get some weird interference when using the HA-2 on my phone when the signal (like indoors).

Yep. Every once and awhile for like 30 seconds.

It's not just the oppo though, my Edifier S730 pick up the interference from it as well when my bluetooth is turned off.

Hmm.. that's strange. How is the telcos signal on your phone like? Full bar? Most likely, from my experience, the phone is trying to get the best signal best possible therefore, there's interference. I dunno about your situation though.

The posts about interference between HA2 and the iphone made my consider not to buy the HA2 sadly enough.

Just put your phone in Airplane mode. You would'nt want people calling and disturbing you while you're listening to your music anyway. I am using an older inactive phone with my HA2 as a media player so I always have it in airplane mode.

Putting the 5S in airplane does solve the problem. However with the 6S it does not.
It appears that particular iteration has earthing issues. Any previous iPhone, you should be fine.
(In airplane mode at least. )

Don't make such a quick decision first, my friend. Go to your local dealer and test them out first. Maybe that will change your mind.

Kris, did you contact OPPO and tell them about your problem? I think you should, maybe they'll send you a new device.

I'm very sorry for any confusion that I may have caused. My experience has been with another amplifier entirely. I was asking about the HA2 as I wondered if it would have the same problem. Then I forgot that I was in the Oppo thread!!!

I don't have it at a local dealer, that's the problem.

Maybe buy mail order from a supplier who accepts returns?
