Bought this item recently. We are okay with the sound quality. But not fully satisfied for the price we paid. HDMI cable not working at all. So have to rely on optical cable. This might be causing a compromise on sound quality. I couldn't figure out a way to communicate with the seller and also tried to contact Bose directly for something else. Long delay and eventually sent a message in their FB profile . They replied that I have to contact Bose directly via the call center. With the remote control , it does not display when you up and down the sound on display. So, in a nutshell, good product but poor & frustrating customer service . When you need a technical support or have questions, nobody is there to answer or rectify it.
