I charge 602 with wall charger along last night (up to 10 hours).

When I looked at the battery gauge in the moring, it's at 2 out of 4 blocks.

I hard reset, but it's still 2 out of 4.

 

Can anyone share the solution ? Thank you.

Try charging thru the USB cable from a computer to see if you have a defective AC-charger.  If still no joy, you may have a defective battery.  When you plug it in do you see the LCD showing the battery being charged (upper-right corner)?

You might have had the player playing while plugged in to the wall.  Power it off first then plug it in and leave it alone.  See if that works.

I tried it with the charger pluged in and yes you are right the noise disappeared.  When I unplug it the noise came back.  This occurs on every iem i used even the monster turbine.

For me, I think there is an issue with my HM602 amp (some filter capacitors???) that this noise is heard when I test the Re Zero with it.

Dont know what is the difference between RE262 and REZero except ReZro has 16 ohms, may be these type of IEMs cause the HM602 amp to go out of wacks. (No noise is heard when both iems are used with HM601).

Once the noise is heard, it will remain constantly while Hm602 is powered on. To get rid of this noise the HM602 must be powered off for at least 2 hours, seems that all capacitors/amp must completely discharge. During this time of course USB and wall charger are not to be used/connected! and avoid using ReZero or same type iem until Fang can confirm if HM602 Amp has improved.

Maybe now someone can try different types of IEMs that are suitable for HM602 .

Is firmware 0.03 the latest? How do you upgrade the firmware etc?

wo ye you yi ge 602, 602 shi wo men zhong guo ren de jiao ao. zhong guo zhu hai city de. niu B ba ? Enjoy..

I'm sorry, could you run that by me again?
