## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for Headphones with TV That Isn't Headphone Ready
*by B***8 on January 25, 2018*

My wife and I like to use headphones when watching TV. When we travel, the TV sets we have access to sometimes do not have a stereo-jack output. And for most (or all?) TVs, the RCA outputs cannot be attached directly to headphones. They must be attached to an amplifier.This very compact unit does a great job of meeting that need. Very simple to set up, and the sound is crystal clear with little or no lag.

### ⭐⭐⭐⭐⭐ Small, solid, smooth controls and all needed adapters.
*by C***F on August 16, 2021*

Nice size, power supply included, does the intended job well.

### ⭐⭐⭐⭐⭐ Great little headphone amp!
*by M***F on March 15, 2017*

Can play loud and remains crystal clear.
