Samson QH4 4-Channel Headphone Amplifier REVIEW


The Samson QH4 is a headphone amplifier with 4 independent channels for audio monitoring. Each of the four channels delivers high-quality audio a set of headphones operating between 16–600Ω. The device features two balanced 1/4” inputs that connect with your mixer or recording interface and a 1/8” aux input port that ideal for connecting to smartphones or computers. In addition to the input ports, there is also a 1/8” output port on the rear of the unit that will allow you to daisy-chain multiple QH4s together. The amp was designed to handle a high dynamic range. The QH4 was built with a master volume control, mute switch, and Mono button (so you can check your phase) for easy control of your audio interface.

The QH4 comes in a very nicely branded box. There are clear graphics on the outside that make sure you know are aware of what the product is on the inside. There are a few limited details included on the box about the product. When you open the box, you will find the amplifier, it’s power cable (with international plug and US plug included) and user manual. To be completely honest, the user manual can be used as a backup for troubleshooting should you run into any issues with set-up because it’s pretty much a plug and play situation.


The QH4 is a beautiful device. It makes it very easy for multiple people to monitor audio recordings, live broadcasts, or even just sharing music. I love how easy it is to set-up and use. It’s beneficial to me even as a listening device. While I enjoy wireless devices, I also love wired inputs because of how good the signal is and for audio recording in particular, I just like the solid connection that a set of wired headphones can provide. The QH4 amplifier makes it so easy to control the volume for an individual channel and I love that even as one person, I can enjoy listening to music through it. I can recommend this for both professionals and amateurs alike. It’s a great piece of audio equipment that can enhance your experience across the board.
