I have a new T3 that whenever plugged into my J3 causes the j3 battery meter to drop to 0 and the J3 shuts down.  the battery is fine (turn J3 back on and batts at 100% again),

 

So Ibasso says the J3 must be sending out a DC output and it needs service.   The J3 is the unit shutting down not the T3, how could an output problem on J3 be the issue?

 

Here is the reson they say it is not happening with D4  - Does this make sense if it is the J3 shutting down?

 

 

The T3 is +/- power supply design. Therefore, it doesnt need DC blocking cap.
The D4 is single power supply design, it has DC blocing cap inside.
If your player has DC output, it can still work fine with the D4.
Please test the T3 with other player. If it works fine, the problem suppose to be the DC output on the J3. You should contact the manufacturer for warranty. High DC output can damage your headphone.
Pleaes check the T3 with other player first and get back to us.
 

 

How can I test DC output on J3?
