Llevo 3 semanas usándolo y la verdad está genial..

I am impressed with build quality, very nice, smooth controls. Will order a second one as a spare, price is great.

Es muy útil y práctico. Tiene un tamaño pequeño fácil de transportar. Los materiales son buenos y en general es buen producto relacion costo-beneficio.

Fa schfo ! Qualità e amplificazione del segnale inesistente ! Non comprate ! Delusione totale non ho altre parole per descrivere questo prodotto !

A great little item, looks a lot better than the grey or black Behringer boxes of the same size; but over all does the same thing.Just make sure you connect it at LINE LEVEL (as stated in the manual) and not MIC LEVEL and it works a treat.If you do connect it at Mic level it's no more than a glorified TRS distributor box and won't give you much amplification/limiting control at all.If you want a Mic Level device I'd personally recommend going for a FiiO amp instead.

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.
