## Description

Review: Quality d class amp - Using it with a set of active 2.1 speakers so far. Needed a remote control for my old set of active speakers. This is the only d-class amp that comes with in/out 3.5 jack aux interface and a remote control. I do like it a lot, it sounds great and the amp iteself is well made and good. However the remote control lets it down. Fire sticks 4k remote can not be configured to control it and the IR code for the remote is not made public by Fosi. So you have no choice but to resort to the supplied remote. It works ok but feels very light and cheap. Would love the product even more if the remote qould be of better quality or at least Fosi made the IR code public. Still for the price it's a five stars package.
Review: Good for the price - Used to power extra speakers for TV and play online content via Bluetooth. Even smaller than expected. Sound quality is good for my uses and the price. Bluetooth easy to set up and works well. Remote is very light but works fine. Metal case robust. Used for a few weeks and all good so far. Will it last well, especially as it is so small and could suffer from heat build up? Overall pleased.

### ⭐⭐⭐⭐⭐ Very impressive
*by A***Y on 3 October 2024*

One of the best purchases I have ever made, blue tooth from phone with sound quality is very impressive best to have good speakers but will still bring out the best in less ,I have Sony MDI 6 ohm and they sound amazing and TV much more natural sounding (sometimes hear background sounds not normally heard, so glad I paid a bit more, really is worth it and this model is at the start of the range!
