Review: P/P PRODUCT - Product grants what it offers. I connected it to my old model Sony 3+1 home theatre system. I needed a bluetooth adapter to connect that old school sound system to my brand new Nebula projector and i ordered that device. I connected it to the audio output of the bluray player, which also works as the amfi of the system, and it synchronised easily and successfully. No disharmony or discordance between the sound and image. It works really on time. Sound quality is satisfactory however there is a deep noise which is audible when nothing is being played. Once you turn on the sound you don't hear it. Which is quite acceptable for a 11 USD device.
Review: Works well - This device works fine. My only complaint is that you have to depress and hold the on/off button for about 4 seconds. It should be one touch for on and off. When it is playing, the button does serve as pause/play, but I think that would rarely be used by anyone. Just make it one touch for on/off.

### ⭐⭐⭐⭐ Basic, but reliable, audio puck
*by D***. on May 11, 2019*

Bluetooth can cut out, but it's rare. Hard to know if it's the rcvr or something with my phone. It does have a friendly voice saying "connected" right before playback. Otherwise, I can say it faithfully connects for hours on end. For best results, don't move the phone around too much during playback. Set it on a table or countertop. I have an older phone used just for music, which sits 2m away on a charger. If there's a problem, it's usually bc the playlist ended or a power spike caused a reboot. This one is best suited for HiFi audio systems using end-to-end RCA cables (wht/red). Mine is hooked up to the input for "CD". Tried "TAPE", but the signal had too little voltage. Any input marked "AUX" should also work well. The single button controls it all; long push to flash the light red/blue (pairing), which also shuts it off after a long press. Once connected, the button acts as play/pause, but no skip function.
