No. The UCA-202 has a headphone socket. Also, the output is just stereo RCA line level, so it should be compatible with other devices (such as powered speakers, cassette recorders, etc.) The UCA-202 cannot be used directly with passive speakers, because the only amplifier it has is a tiny 5v headphone amp, not a power amp.

Note that some headphones require a lot of driving, in which case you may not get very high volume from the device unless you add a headphone amplifier (same is true for most USB audio devices).

I'm not aware of any difference between the 202 and the 222 other than the colour (202-> silver, 222->pink/red) and possibly more bundled software with the 222.

How do they get the cable to stay like that in the picture?

Here is a link to a blog by a fellow who replaced the head-phone driver opamp in his UCA-202 with one with a bit more oomph:

Probably not a practical suggestion for anyone who is not an experienced electronics technician or engineer, but the document does have pretty detailed testing of the headphone output in that box and it's limitations.

As Steve said the results you get will depend heavily on the characteristics of your headphones.

I got the UCA222 (just opened it today) and so far hard to tell but there is a click when ever I start and stop listen/play and I tried all the device options (MME, Windows DirectSound, Windows WASAPI).

I don't have this problem with just using the computer's sound card

BTW I have an HP Presario Windows 7 64 bit - Is it possible my sound card on this computer is as good as the UCA222? --- The UCA222 seems kind of cheap - literally and figuratively. Thanks.

I've not used a UCA-222, just the UCA-202. As far as I can tell, the two models appear to be extremely similar (other than the colour).
There's a lot of technical information and test results for D/A performance of the UCA-202 here: http://nwavguy.blogspot.co.uk/2011/02/b ... eview.html

There are many reasons why a click might occur at the start of playback. One possibility is that the level at the initial playback position is not zero - if this is the case then there "should" be a click caused by the sudden jump to the level at the initial playback position. To test if this is the cause, try generating silence, and then play that silence: is there a click when playback of the silence begins?

Thanks Steve, I tried - on a generated silence and still the clicks.. I do have an HP (computer) (Model CQ5826) COMPAQ PRESARIO 3.2 GHz Processor, 4 GB Memory, 64-bit Operating System. Windows 7 Home Premium 2009, Service Pack 1. All rolled back to factory with no updates (and no internet/on my editing computer) though. So.. I don't know.. But it seems it still should not be doing this --- I will probably return the UCA222 for a refund soon - thanks anyway. A German company/-- yet made in China! - darn. $$! Though I just downloaded what I could at Behringer.com /downloads /UCA222 to see if maybe a driver or something may need to be installed[??].-- No, no drivers --- just an old copy of Audacity and some podcasting software and a manual.. Looks like it's going back. Thanks anyway. Wait --- there are drivers and other stuff -- so I'll see.

Does this seem right?:

Also at "Load More" ..."effects, hosts, instruments.." A lot of stuff --- I don't even know what half of this stuff is. But immediately I think the driver may be the only thing that could save this device's functionality.

Do you hear a click if you plug headphones into the UCA-222, or is it only when playing through an amp?
I'm not convinced that your UCA-222 is faulty.

No. Audacity does not ship with ASIO support, so you can't use Asio4All without building a modified version of Audacity.
The UCA-222 will work with standard Windows USB audio drivers (for once it's something that really is "plug and play").

I've only tried with headphones so far (computer > UCA222 > headphones) --- and I tried switching the monitor switch on and off and adjusting the volume (both on the UCA222) to no avail --- though I have not tried hooking my stereo up using the UCA222. I'll try that ASAP.

Tried through stereo (computer > UCA222 > stereo > speakers) and still getting the click ---.
