OPPO HA-2 Portable Headphone Amplifier/DAC Discussion Thread

Why my HA- has trouble charging from a non-name 2,600 mAh portable power bank? it was given to me by my company so tried to charge my ha-2 and it starts charging well first led blinks and whne 2nd led starts blinking then the first one from the 4 leds glows blinking red and the 2nd stays lit in green
 
what is that?
 

Update: whe charging the oppo with the battery pack the batteyr pack gets hot, as if the oppo was demanding more current or so
 
but charging my xperia or my walkman A17 doesn't exhibit this behaviour, the battery pack stays at room temperature

I'll take a chance at $10+, the stock cable is fine for desk use, but portable use is a bad accident waiting to happen.

 
I agree, the stock cable is not good for portable use. Neither is the v-moda cable, even though it's much shorter.
 
I got mine in last night, and it works perfectly. The 90* Zesck lightning cable is about the same length as the v-moda lighting cable, but has a much smaller profile when in use. 
Now let's hope it's rugged enough to survive daily use...

Nope also with my smartphone exhibited the battery pack getting hot and only charging it to 50% and then the smartphone started going on and off
 
I only want to know why the HA-2 displayed a red blinking led and a solid green one at the same time

It sounds like you have a defective battery pack. I had used my HA-2 for maybe 6 hours. I plugged it into a Aukey 20K mAh pack. It charged up just fine. The pack never got warm.
 
I have a "lifeCharge" 10.4 mAh pack I will try. Just curious at this point.

this one is a 2,600 mAh, made by Mobile Power... but has the logo of my company (I know those freebies company give off with their logos). Well better charge the HA-2 using the wall charger

You are probably better off. It will charge faster... and at 2,600 mah, that thing will not charge the 3,000 mah battery in the HA-2 fully anyway.

Mine should get here this week, angled adapters should be a given on any Portable amp, DAC and Source.
 
Instead I'm always paying out of pocket for the right connecter, seriously is it that much cheaper to throw in a non-angled adapter?

Thanks for the very informative posts on this thread guys. I read them all! And got myself a HA2 last weekend and it's been all bliss :)

I was disappointed with the sound from my iPod (am unsure which generation) but was unwilling to let go of its huge storage capacity. A proper modern world solution would have set me back much more than 300 bucks.

Here's how I am satisfied with the sound from my iPhone (first a 5s and then a 6 Plus):
I installed Onkyo HF Player on it, loaded HF Player with 96 and 192k tracks, hooked it up to the HA-2, and listen via PM-1 and PM-3 phones. Hi-res bliss indeed!

Hey all, just thought I'd chime in and say I bought this case for my HA-2 and it's a perfect snug fit! Will surely keep it protected and and has a spot for the OTG cable also.

This is Australian but not sure if available in other countries also.

Thanks i did that and yes charges faster, even from pc :D, the same for my mobile phone which also has a 3,000 mAh battery, perhaps i will leave this freebie for phone emergencies or for my walkman which has a lower mAh battery
 
and as a side note, try to charge the HA-2 while OFF, it can get a bit hot if you charge and use it at the same time...

Am going to do it now.
Is there way to get HD tracks into Onkyo HF on an iPhone without using a PC?
Thanks for the tips!

I got mine Friday - works great...
 
so far
 
I also have used this cable - seems to be pretty hardy - it uses a flat cable so the bend doesn't seem an issue. 
 

 

 
Also got the cheapie case in the mail and the HA-2 fits snugly, but it fits.
