I bought a FiiO D3 (D03K). Worked fine. Was very happy with it. Then after a few weeks the thing went bad, produced distorted sound. I got another one. Same story. Finally it dawned on me that it was permanently powered up. So I tried disconnecting the power feed, letting it cool off. And then it went back to working OK. Now whenever I wanted to watch TV I had to first go and plug in the USB power cable; when I was done watching, I had to go and unplug it. I was a slave to this overheating $25+ piece of junk.
Enough is enough. I shopped around and bought this Orei DA21. Seems to be a superior product. It automatically detects whether input is optical or co-axial (the FiiO requires you to set a switch); in addition to the RCA outputs, it also has a 3.5mm headphone output; and the sound it produces is louder and clearer. For the time being it certainly outperforms the FiiO.
Well, it's now been a bit over 2 weeks. Awesome improved sound (compared to the FiiO). Moreover, it's been permanently plugged in and no sign of overheating or misbehavior (by now the FiiO would require being unplugged and allowed to cool).
Product doesn't work when AC power is switched off and then on again. Solution: Do not turn off AC power to the unit.
Thanks to Amazon, I got a second unit shipped to me after I found a problem with Orei DA21X, as described in detail below. Alas, the second unit also has the exact same problem. Problem aside, the unit works as advertised, although I found the output signal a bit on the weak side, which, however, can be fixed by cranking up the volume.
When I connected the Orei DA21x between my LG TV's optical digital output (set to PCM output as recommended by Orei), it seemed to work initially. However, the next day there was no signal out to the amp, even though I could see the laser beam in the digital optical cable from the TV. When I disconnected and reconnected the DC plug from the AC/DC converter (the only way to "reset" the device), it started working again. Thinking there was a flaw with the particular unit I received, I exchanged it for another unit with Amazon. Surprisingly, the new unit suffered from the exact same problem! (I wwitch off AC supply to all my electronics - including Orei - at night, and, upon power up next day, Orei doesn't work until a hard "reboot" by disconnecting and reconnecting the DC plug into the unit.) I figured the problem starts with me switching off the AC. As an experiment, I unplugged the AC plug of Orei's AC/DC converter, and sure enough, it stopped working when I reconnected the AC plug. I repeated this on both units. So, if the AC power to the unit is off, it seems to go into a weird state, and the only way to bring it out is to do a "reset" by disconnect/reconnecting the DC connector.
To fix the problem, I have connected it to a non-switched AC power strip (i.e. one that I don't turn off at night). And now it seems to be working fine. However, since I travel, I will turn off AC to all the electronics in the house, including Orei. When I return, I suspect I'll have to "reset" Orei as described above. This is a hassle, as the unit is at the back of a cabinet, behind a drawer. I have to pull the drawer out, reset the device and then put the drawer back into position. For reasons I won't go into here, I don't want to put it out where I can access it more easily. I'll see how the current setup works out - if it turns out to be too much of a hassle, I will have to look for another manufacturer.
I wrote to Orei's customer support with a detailed description, and, got a standard "you must put TV in PCM output mode... blah..blah" e-mail and when I wrote back saying that wasn't the issue, they never responded. While I don't expect them to do a gymnastic exercise of fixing a product that's around $26, I would at least expect them to read and understand the issue and respond that they'll look into it, rather than sending a form letter addressing an issue that I don't have. Clearly, the problem seems to be a design flaw.
One star for the product doing what it is supposed to do when it works. Minus 4 stars for having to "reset" the device, the disengaged customer support and the design flaw. (Other people have commented that the unit seemed to suddenly stop working, and, I suspect it may be the problem I encountered.)
Here the icing on the cake was finding a wireless headset that doesn’t “live” on the transmitter, as most do (i.e. close to the TV): I chose the Sony MDRHW300K Digital Wireless Headphones. Like this I can have the actual headset in my bed side table (it charges via USB) and when the need arises, just mute the surround speakers and continue listening on the headset, all without having to move my lazy butt… And as the headset has its own volume adjustment, you’re all set :-)
