It works fine but in your review you wrote about a charging LED. Mine has a RED led while charging and a white led while it's on. The led does not become green when charging is complete.
I will contact iBasso about it, I figured it was just imposible to charge while listening. It is heavely scratched as well after all these years.

Besides the one included in this thread, I don't recall ever writing a review for the T5. I also don't recall mentioning about charging or green LED. In fact, mine works just like yours - red LED lights up when charging and goes off when it is full.

I would personally go for the UHA-4. From the comparison and impressions before, it seems pretty spectacular.

Yes, UHA-4 would be a pretty good choice, though it won't have a similar sound as T5.

Hey all. I want to ask about the ZO2.
 
I got the HRT Microstreamer a while ago, and while it has some pros (clarity, highs extension), it is downright bass anemic imo. Point is, I need more bass. 
 
I was thinking of something like this 
 
PC >>> HRT Microstreamer >>> ZO2 >>>> Sig DJ
 
My question is, would this setup be idiotic? From ClieOS's view, the ZO2 is one of the worst sounding amps in this group. So, would it be stupid to use the Microstreamer as a DAC only, and use the ZO2 as bass boost?
 
The intention is to maintain the positive qualities of the Microstreamer and add bass, but I am thinking I would lose the clarity from the Microstreamer if I use it as DAC only.

Here's another user reporting the same issue and another commenting he has no problem listening while charging.
I suspect a short somewhere because when I connect IEMs only one third to two thirds I can hear parts of the distorted output.

Yep, like I said on that (and this) thread, there seems to be some serious build quality issue on T5 and thus it is never the amp I'll recommend. My battery actually ballooned up in less than a few months with very light usage. I replaced it myself with a generic eBay Li-ion battery of the same size and it has been working fine all this time. I'll say there could be something doggy about the battery iBasso uses in T5 that causes all the inconsistency among user.

Probably, could you describe how you took apart your T5 without damaging it?
I found another user experience somewhere where the user is also unable to charge and listen at the same time.
 
iBasso answered my e-mail. They say charging while listening is not possible.

T5 is really easy to take apart, only 2 tiny screws holding both panels together. Just unscrew carefully then use you finger to pry the two panels with your finger nail on one end (the one closer to the screw hole). One of the two panel (*forget which) will be easier as the other one will have the battery glued on with double side tape. The tricky part is actually when you need to put everything back, when you need to align the two panels just right so the tiny screw can screw into both of them. Also be sure not to over-screw and damage the thread.

I guess I have the defected T5 then? In a way I am kind of glad it defected the way I want it

, but that's nonetheless a serious issue. Again, I am disappointed with iBasso.

Amend the review to reflect this.

  Would either C 421 work well with the Audeo PFE? I would get the C5 but I can get a C 421 for half the cost of a C5, the only problem is the seller isn't sure which model it is.

I'll expect PFE becomes slightly brighter due to the output impedance of C421.

The saga here continues.
I am unable to listen and charge via USB connected to my computer but I can listen and charge via 220VAC-5VDC USB connected to the wall.

  I was charging using a wall charger and not via my laptop, will have to try that and see if it still plays.

Could be some kind of ground issue, as BTL / balanced ground design will require much more complex charging circuit to isolate the ground channel from the electrical ground and T5 simply doesn't have the space needed. It could be that iBasso chose to cut corner by not isolate them and thus creating the issue we have here. E11 has the same problem but FiiO decided to automatically turn the amp section off when charging. It would also explain why some have noise issue while other don't, as USB port implementation is different from PC to PC. A good USB port will proper power filter will likely have no noise issue. Actually I can use my T5 on both PC as well as USB adapter while charging,
