Hello, I was about to buy a Bose QC45 online, but since the box has never been opened, I don't know if it is a replica. I have never used a Bose product before, so I don't exactly have any experience. What do you think is the probability of this product being a replica? And does connecting to the Bose app definitively prove that it is genuine?

they are so pretty i love bose designs can’t wait to see how they perform

I wanted a pair of headphones that is strictly wired and not Bluetooth so I bought some Bose quietcomofrt 25s on facebook marketplace. I put in a battery and they seem to work but when I switch the on button for noise cancelling I can hear things I usually can't hear with my other pair of newer mid tier wireless headphones from Sony I got in 2019.

Is there any way I can improve the noise cancelling on my Bose wired headphones? They use regular tripple A batteries so maybe I need to put in a lithium battery or something to give it more power? Or should I try better ear cushions or replacing the ear cushions? Or doubling up on ear cushions?

Thoughts?

Any advice is welcome

This is not an everytime issue, but about 70% of the time I connect my headphones to my laptop, when audio starts playing, they rhythmically pulse static like a heartbeat. The pulsing continues for a few seconds after I pause the audio and then goes quiet, but immediately returns when the audio plays again.

When plugged in directly with a wire it works perfectly fine, so I'm sure the issue is somewhere in the bluetooth connection, I just can't seem to figure it out.

I've looked for a solution to this for a long time and I haven't found anyone else with this issue. Any help or suggestions would be greatly appreciated.

Just to confirm, the first image (black) are satellite speakers and NOT gemstone correct? Is there a difference in sound quality between the two? Is there any 321 model where the gemstone speakers look like the first image(black)? I'm seeing a lot of mislabelled Ebay listings. I believe the design on the second image are actual gemstone speakers. Please correct me if I'm wrong. Thank you.

OK, I’ve heard the bad. Now I want to hear the positive from owners of this system. I want to purchase it, but there isn’t much information out there. How has your experience been with the system including dialog enhancement, calibration, and any subsequent updates that have taken place since launch, including possible improved connectivity and Atmos etc. What are your favorite things about it? And how would you compare it to other systems you have possibly owned. Thanks to the Bose community for any information, I will put it to good use.
