    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.

    Good Quality for the Price

    Pros: Nice construction and feel.
    Good sound quality.
    Loud volume.

    Cons: No optical input.
    Not very punchy on bass.

    Comparable to Fiio products in the same price range. Seems to be functional and works well. I'm using it with Sennheiser HD595s.

    Pros: Looks like the picture, reasonably well made.

    Cons: Extremely low performance in low and mid-range frequencies. Basically, it does nothing for them. Bass is a joke and on most tracks you barely hear vocals. Doesn't matter if you're looping through AUX-in or the DAC, the amplifier just doesn't like those frequencies. It will leave you a great amount of disappointment.

    Based on some of the reviews I decided to give this a try over more expensive options for a desktop headphone amp. It's a complete let down and I'd skip it if you actually care about listening to your music. While the device appears to beand iswell made, it falls down on functionality and performance.

    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.

    Volume knob came broken

    ordered these through monoprice on amazon, since they have is listed cheaper there. The volume knob does not turn off the device, as video reviews have shown online. I have to unplug the device to turn it off. The knob also keeps turning, so after the lowest volume if i turn it more it reaches max volume.

    Thank you for your review and my apologies for the issues you have experienced with PID 11567. Unfortunately, it sounds like you may have received a defective product. It should power off when the knob is turned down all the way and click. I would recommend requesting a refund or replacement by sending an email to our Amazon Support department at Going through our Amazon Support channel is due to Amazon's third party selling rules. In the email, please include your Amazon order number and a brief description of the issue with the item, and they will be able to assist you.

    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.
