We’ve all shared earbuds and used headphone splitters to share music and listen with others. In studio settings, multiple people often need to hear the same thing at the same time, and it takes more than a simple splitter adapter to get the job done. Unlike splitters, a dedicated headphone amp sends the proper amount of power to each pair of headphones, preventing distortion and overloading that can hurt your ears and damage your headphones. It also prevents you from tangling with an endless sea of adapters and cables when you’re trying to feed audio to a whole group of people. For protecting the ears of producers and musicians and making sure everyone’s audio is crystal clear, a multi-headphone amplifier is a must.

Here’s a list of the best multi-headphone amplifiers currently on the market.

This compact headphone amp from Behringer is a great solution for small project studios with limited space and limited needs. It runs with an included 12-volt adapter and powers up to four pairs of headphones in stereo, each with their own independent volume control. The input takes one ¼-inch stereo plug and distributes it to four ¼-inch stereo outputs. This would be a great solution for voiceover and radio studios where multiple people are working together.
