    Desktop Headphone Amplifier



    Get superior audio reproduction from your computer and audiophile headphones using this Desktop Headphone Amplifier from Monoprice!

    This headphone amplifier features a USB input and a professional level Texas Instruments Digital to Analog Converter (DAC), effectively replacing your sound card without requiring you to open your PC and installing a new card. The high-current output allows it to drive headphones with a wide range of impedances, from 16 ohms to 600 ohms.

    The RCA line outputs allow you to send the output to a stereo amplifier or powered speakers for those times when you don't want to use headphones. A set of RCA line inputs allows you to connect an external audio source, such as a CD player, so you can enjoy the advantages of the high-current headphone output with other audio sources.

    Not bad, but not polished

    Pros: Decent sound quality
    Decent price

    Cons: Does not support standard headphones
    Does not come with 1/4"-to-3.5mm adapter to use standard headphones
    Volume knob scrapes against body unless you pull it out slightly
    No pass-through: line-out doesn't work unless device is turned on
    LED power light is too bright

    I think my two biggest complaints would be addressed by including a 1/4"-to-3.5mm adapter in the box (or just using a normal headphone jack in the first place), and having pass-through on the line-out so that I don't have to turn the device on even when I don't want to actually use it.

    This seems the sort of device where several small tweaks could take it from a 3 to a 5.

    Does the job

    Pros: Does exactly what I needed: increases the headphone volume from my PC's audio out jack. My PC is my primary multimedia player. Often the audio wasn't quite loud enough for my aging ears. I had been using a FiiO portable amp to jack up the sound but it has to be re-charged after a few hours use. The Monoprice headphone amp is powered by a wall-wart so it's one less gizmo to charge.

    Cons: No serious complaints:

    1 Missing the obvious mini-stereo input jack or an included adapter for use with a PC. The Aux. input is a pair of RCA sockets and RCA cables are included but all my PCs have optical and mini-stereo jacks so I had to dig through my adapter collection to find the right one. Also had to dig out a standard stereo phone jack to mini-stereo adapter for my earbuds. For the price, an optical input might have been included as well.
    2 Adds yet another wall-wart to the collection.
    3 Very minor point, but I would prefer that the volume knob had a bit of surface texture it's so smooth that sliding my thumb on it to turn it on takes more pressure than I like.

    I can make my headphones louder than I need. I can't say if the quality of the sound is better it's definitely not worse and maxing out the PC volume does not generate obvious distortion. I'm entirely happy with the product's performance.
    Unlike some of the other reviewers, the knob on mine is nicely aligned.

    GREAT HEADPHONE AMP!!!

    Pros: Great sound and now I can really enjoy my Audio-Technica ATH-M50x. Price point is good.

    Cons: I hesitate to even list this as a "Con" but, I would have liked to have a smoother feel when using the volume knob. This is very minor and should not sway your decision for making a purchase.

    It is a little bit bigger than you think, if you are looking for an amp to be portable while listening to your music/podcasts/movies on your phone while you are on a bus/airplane/train, this will not work out for you. If you are going to put this in a stationary location, then this is not a big deal.

    Love this amp! I was looking for one I got put at my desk at work and this works very well. I am using it with my M50x and my HTC ONE M8 and it does a great job. Well done Monoprice!

    Pros: Solid Base Build
    Good smooth feel on volume adjustment
    1/4" Jack

    Cons: Flimsy Volume Knob, Glued on Crooked so feels weird when adjusting volume.

    Works as stated. Only have used USB DAC input so far. Plenty of volume for over the ear headphones. Volume knob large and easy to turn. Was able to remove volume knob (it was hot glued on) and re-adjust so that it turns more level.

    Nice!

    Pros: Sound good, looks good, will serve as night light when on

    Cons: No cons regarding its performance as headphone amp. The blue LED when powered on is bright enough to serve as night light in a dark bedroom. Easy to fix if that bothers you.

    I use it with my Sennheiser HD485 high-impedance headset. It is clearly better than the headphone out of my CD player and also, but by a smaller margin, my FiiO E6 headphone amp. Have only used the RCA inputs, not the USB digital input. It is immediately clear that the bass is a bit clearer with this amp. Within minutes is also becomes clear that the sound is more open, instrument (when listening to classical music) are better defined. No fatigue listening to loud, complicated passages. Quite pleasant. Brings new life to music. I have no experience with other headphone amps than the ones mentioned. I feel I have gotten my moneys worth and am happy with this purchase.
