Review on 🎵 KEiiD Bluetooth Stereo Receiver Amplifier with Adjustable Treble and Bass, 2.0/2.1 Home Audio System with AUX Input, 3.5mm Subwoofer Output and Remote Control by Kim Navarro

This is a different KD-W03 than the one I bought (KD-W02). Key Difference: KD-W03 only supports Bluetooth connection. KD-W02 supports Bluetooth and WIFI connection. As I found in my KD-W02 review, all of my ceiling speakers are connected to a tech room in the basement, so a WIFI connection seems like a must to me. However, I found that my dining room was directly above the engineering room; So I bought a KD-W03 to try. The track is good. The Bluetooth connection (between the mobile phone on the ground floor and the KD-W03 in the basement) was stable. At the moment I have 2 KEiid receivers in the technical room. Kitchen: KD-W02 via WIFI. Canteen: KD-W03 via Bluetooth (costs much less). Tip: Bluetooth can only penetrate 1 wall or 1 floor. If there are more obstacles between your audio player (e.g. mobile phone or tablet) and the receiver, you need the WIFI version. Otherwise, you can use the Bluetooth version to save money.
