Review: Awesome Amp - So far I have only tested with one of the line outs but I will be testing the other soon with additional headphones and cords. Quality is outstanding, I compared several headphones on output 1 and compared with a Polk Surround Bar, even modest over the ear headphones sound as good or even better then the 300$ Soundbar. I feel the quality of the amp is more then adequate as the audio sounded rich and clean to my ears. Obviously headphone quality varies dramatically and I tested with the Sony MDR ZX300 my old ISymphony Noise Cancelling and the Seinhesier HD 201. The change in headphones was very interesting to pick up the small differences in the similarly priced headphones. I thought the bass response on the Sonys was nice but I like headphones that fully enclose the ears to block out noise, amazingly scenes with thunder and base were very good, better then the subwoofer was producing. Surprisingly the Sonys were not bad for the price still I expected a little more based on the reviews I read. To get much better performance you need to likely spend at least 70$ and I would love to test the Sony 7506's at some point in the future. Back to the Amp, it serves its purpose well, volume only needs to be at 1/3 for the Sony headphones to be loud, plenty of power for all the Cans I tried. Looks nice and volume controls work well being on top. You will likely need 1/4 adapters as this unit takes full size plugs. Really no complaints for the price, I needed an amp to go from my Digital to analogue converter so I could get audio of my TV on headphones, this way the kids can sleep and I can use my new Plasma to watch some movies at night. For now I'm outputting from my Sony Bluray player which has a Coax digital out while I wait for my optical dual output adapter to arrive. Once that's in I will be able to have audio on the sound bar and headphones at the same time from all inputs to the TV. Figured it was better to go dual output then use a Toslink switch. Its surprising to me that some TV's now only have a single digital optical output. Anyways to sum up, for 17 bucks you get an amp that powers four sets of headphones from a single 1/4 stereo jack source, just make sure to buy some adapters and long cords or hook up your wireless headphones and you should be all set. I imagine this unit would also work well for labs and you could also further split with y adapters, I did this briefly so I could compare two headphones side by side, you will need to obviously crank the volume up though if your driving two sets of headphones from a single jack. I imagine ear buds would need very little juice to power, mine were all over and on the ear sets and had plenty of power from the amp.
Review: Outstanding value - just be aware of its limitations. - I believe several of the negative reviews should be taken with a grain of salt. Likely some of the users are simply not connecting things properly (e.g. several comments about only the left channel working suggest plugs not fully inserted, likely the 3.5mm plug is not completely inserted into the 6.3mm adapter, as many of the adapters require significant force to make the correct connection). I do sympathize with users who have legitimate problems with non-functioning units, as the price is so low as to make shipping costs for repair or replacement hardly worth the bother. But then, we should be happy that the price is so low! This is a low-power unit, not intended for speakers, and not really great with low-impedance (e.g. 8-ohm) headphones. Even with 32-ohm and higher headphones, you will likely be disappointed if you want to really crank up the volume to eardrum-splitting levels, particularly with several headsets. The user guide states that the output impedance is 80 ohms, but in fact it's at least 470 ohms, because there is a 470 ohm resistor in line with each output connector (I made oscilloscope measurements, and opened the mixer to visually confirm the resistance) That will seriously limit the current to the headphones (but that's necessary, because the very tiny integrated circuits could otherwise overheat), and for inefficient headphones with very low impedance, will likely give somewhat muddy bass and noticeable distortion at even moderate sound levels. BUT - what do you think you are getting for less than 20 bucks? This is a very capable device, producing quality sound at moderate levels with appropriate headphones. Mine is well-constructed, no issues at all. I can barely detect a miniscule amount of noise when there is no input and the volume is cranked all the way up, and with 100 ohm headphones the volume level is very satisfactory and the sound is very clean. If I were an audio professional, I might look for something with better capabilities, but I would be paying a lot more for that, and I have no need for it. Five stars.

## Questions & Answers

**Q: Are the individual outputs amplified beyond normal "line-level" voltages? In other words, if the input is at max volume, will the output be louder?**
A: The amplifier circuit has a maximum voltage gain of 10 (20dB).  However, the actual gain you can get will depend on the impedance of the headset you plug into any given channel.  The design calls for a 47 Ohm output resistor for each channel, but the two I received were manufactured with 470 Ohm resistors installed, so the output impedance was ten times what it was supposed to be.  People getting units assembled with this error will see far lower gain than they should.  Beware!

**Q: could this device be bridged like a car amp?**
A: If you mean could you listen to headphones in the car with this, it is possible if you are a good technician or if your car unit has a “pre” or “pre-amp” output.   Trouble is the device has a wal-wart that wants alternating current and concerts it to direct current but you could look around for a CLA with the proper output voltage and tip.  So with a pre-amp output, the proper cabling, (rca l/r to 1/4” stereo or trs) and the appropriate power supply this will power headphones in your vehicle.  CAUTION:  Using headphones while driving is illegal in many jurisdictions- check your state or local traffic codes.  This will not drive speakers well by the way... the output power is too low.  Good Luck!!

**Q: Can i sub the power supply for a 12vdc usb cable? would usb sufficiently power this unit?**
A: USB ports supply 5V, not 12V, so, no, you can't power this thing with a USB cable.

**Q: Can this be used to amplify the sound coming from microphones in an auditorium (I will be using headphones)**
A: I very much doubt it.  This is a "line level" amplifier.  Line level voltage is much higher than the voltage coming from a microphone.  This amp is not designed to amplify a microphone.

### ⭐⭐⭐⭐ Awesome deal with a few nit picks
*by D***D on January 6, 2015*

I am very satisfied with this amplifier, its size and price are definitely deceiving. When I have my headphones plugged in wether I am listening to something or not there is no white noise created by the amp itself. This amplifier is STEREO sound! many amps in this price range/size are mono, and I didnt want mono sound. The sound is not diminished when another pair of headphones is plugged in and all the knobs work as intended (aka when one channel is turned up the other audio channels do not suffer in quality or volume). The knobs themselves dont have any slack and are firmly attached. At first I had a few issues with sound coming through one side only (as some other reviews had mentioned) but it was simply because I didnt have the jack firmly pressed in, once pressed in ALL the way the audio sounds even better coming out then going in. There are a few things to note if you are buying this: 1. This does not come with an input cable, you will have to supply your own. 2. these are 1/4 jacks so if you have a standard pair of headphones or other accessories that have "small" (1/8) jacks you will want these (I got these as well). amazon.com/gp/product/B00PIWB2SO they are good quality, cheap and theres 5 of them so you have one for every port if need be. 3. The AC power cord is rather short, 3 foot, maybe 4 foot max. This made it rather inconvenient for me because my power source is just a bit farther than that. Other than that this is a very well built amplifier that is worth the price you pay for it, I just wish it had a longer cord.
