Whether you’re editing videos, recording in a studio or just want to listen to some music with friends the Samson QH4 Four-Channel Headphone Amplifier has got you covered. Designed to distribute audio to four individual sets of headphones, the pocket sized QH4 is the perfect on-the-go and desktop accessory.  Ideal for your home or project studio, the QH4 lets you connect up to four headphones at the same time via ¼” inputs located at the front of the unit. Every channel has a separate level control so each listener can dial in their own volume setting as the signal comes through. The four individual amplifier channels offer volume control, clean crisp audio for up to four sets of headphones at once. For overall control of your sound, the QH4 is built with a master control knob and a master output mute control. Engineered to give you the ultimate listening environment, this small but feisty tool has an ultra-low noise floor and a wide dynamic range.

Volume Boost

In addition to distributing your mix to different listeners, the QH4’s four independent high power amplifiers boost the dynamic range of the signal resulting in ultra clean, smooth, high gain audio. The systems circuitry is designed to provide an ultra low noise floor so your mix comes through uncolored. A master volume control and mute button allow you to quickly apply changes for all listeners.

Flexible I/O

Along with the four well engineered headphone inputs, the Samson QH4 Headphone Amplifier is made with enough connections to integrate into any recording, editing, or leisure situation. Featuring two ¼” inputs, a stereo 1/8” aux Input, and a 1/8” aux output you can connect this device to a mixer, recording interface, your smartphone, or other QH4s!

Check your Phase

Upon further examination of the QH4 you will also notice a Mono Button. Engaging the Mono setting allows you to check how your mix will sound on Mono music playback systems. This is perfect for double checking the phase of your recordings. Dual ¼” and 3.5mm stereo inputs provide maximum capability with a variety of music sources.

Mono Ready

When recording and editing music, videos, podcasts and more, you should always ensure that your mix can be played in both stereo and mono. The QH4 features a global Mono button, which allows you to quickly check the mono compatibility of your tracks. The global mono button also allows the user to split a right and left feed from a stereo interview, to hear each track in one side of the headphones, making for quick monitoring of a podcast or any recording with split tracks.

Need to Be Loud But Quiet This Is It!


Love this thing! Need to be able to jam and not be loud and this is the best solution!



Small and portable


The Samson QH4 headphone is great for anyone that is light on space but wants multiple people to hear what is being played. With 4 individual channels this is ideal for bands that are on tour and wanted to record demos while they are on the road. Really good clear sound.

I love it


Finally a simple headphone amplifier for everybody! Sometimes it's hard to find a good headphone amplifier that can be used in the studio or on the stage at an affordable price. This product is very simple and easy to use, nothing about it is complex. This is a great buy and I'm glad Samson put out a headphone amplifier with this design. This review is from Ellis at Sam Ash in Richmond, VA.

Great Little Headphone Amp!


This is a great headphone amp if you don't have room for a rack-size headphone amp or are on a budget. It doesn't take up a lot of room so it's great for smaller recording setups. For input, you can run a 1/4" mono signal into it, and for stereo, you can run left/right TRS 1/4" or stereo 1/8"--so you can pretty much get any signal from any source into this unit. For output, there are four 1/4" headphone jacks (each with its own level control built into the top of the unit so they are easily accessed) and an alternate stereo 1/8" out the back. This also features a master level control and a mute switch. For the price, you can't beat this unit! I am a verified reviewer at Sam Ash Music.
