    Polsen HMA-41 reviews

    HMA-41 4-Channel Stereo Headphone Amplifier is rated 3.7 out of 5 by 7.
    Rated 5 out of 5 by from 4-Channel Stereo Headphone Amplifier by The output of our recording system is one line for headphones. To use multiple headphones to listen to the same recording a single line must be amplified and then split, in this case, 4 outputs. It does a very good job of this. It's compact and hence doesn't take much space on the desktop. It does exactly what I expected it to do. It's great for a novice application, like mine.

    Rated 4 out of 5 by from Good for the price We are not audiophiles. Used so two people can watch TV with independant volume control. Work just fine for our purpose.

    Rated 2 out of 5 by from You get what you pay for Construction on this thing is fine, however the crosstalk between channels is BAD. Even when the volume is completely down on say channel 3, the speaker I have plugged into 3 still receives audio. Returning product immediately.

    Rated 2 out of 5 by from Ok, But! OK for a cheap headphone mixer. It does have bad crosstalk between the outputs. If one is turned off you still hear the feed if any other headphone output is up.

    Rated 4 out of 5 by from Works Well! For the price I was not expecting much. However, I was pleasantly surprised at the quality even though it is an inexpensive device.
