Behringer HA400 Reviews

I needed something better than the onboard amp

By Ivan K.
Rated 5 out of 5
Date: 2025-06-19

I was using my headphones with the on-board headphone interface on my desktop and I found myself hitting the limits of what the sound interface would do for amplification and just found it totally inadequate. After finally setting this thing up on the Line Out on my computer (the manual does not make it totally clear which output to use) this thing does the job so well it could damage my hearing if I wanted it to. Perfect for the price!

Perfect Little Headphone Amp

After plugging in my headphones, I could tell no difference from being plugged in at the source, or through the amp. What a perfect bargain for the price!
