Review on Bestisan Bluetooth TV Sound Bar 60W 24-Inch with 3 Equalizer Modes, Remote Control, Powerful Speakers, Deep Bass, Optical Aux Coaxial Connection, Mount Kit, Wall Mountable - Enhanced Soundbar by Paula Rodriguez

I bought an earlier version of this soundbar from BYL and liked the sound but had to return it because it had a slight hum on the RCA and AUX inputs generated. After returning the old model, I bought this new unit, but it has the same problem: when inputting an RCA or AUX source, the unit emits a low hum with a constant, low "click" noise. I've tried multiple outlets, cables, input devices, etc., but the moment the unit is turned on and the RCA or AUX source is selected (even if nothing is plugged into that input), there is a hum. B/T and optical have no hum and sound good. But my TV only supports variable volume on RCA so I have to use that. Either BYL should let me know there is a fix (and I submitted a support ticket last week with no response) or I should return that as well. I'll delete or update this review when I get a solution, but other buyers should beware: if you want to use the RCA or AUX inputs, 2 out of 2 units I've bought make a hum when RCA or AUX inputs are selected . I updated this review because the seller contacted me about customer service, but I have already returned the devices. The unit's sound was good given the price, and the remote TV sync feature (which worked great on my Comcast remote) is very useful. I can recommend a device in this price range with the limitations mentioned above.
