BDS 635 is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from great system, pure sound quality I brought the system just from the 5.1 and I'm blown away by the difference from my sound bar, I was impressed with my sound bar but this is in a different league. blue ray is good at upscaling, does the job.

Rated 4 out of 5 by from Could be better It was well packed and I spent a while setting it up. I had problems linking my SKY Hub but eventually succeeded. It sounds great but my greatest disappointment was it won't play my Bluray 4k Dvd which I had bought especially to compliment my new LG OLED television. I had updated the HK software but it still rejected it as unreadable.

Can this system be used in 3.1 mode, i.e. can you choose not to use the rear speakers?

Asked by: Belly
Hi, You can't disable the channels in the settings, so you would have to physically disconnect the speakers. Please also be aware that when the system is set up for surround sound, you may loose some sound effects etc. when watching a movie. I would suggest that you disable a surround mode in that case, and choose multi-channel stereo. For more information, please contact our Customer Support

Hi, does this unit have a standard headphone socket or will it output to Bluetooth headphones? Thanks, Adam

Asked by: AdamS
Hi Thank you for your question. The BDS x35 doesn't have a headphone socket nor is it possible to connect a bluetooth headphone to the BDS, since the bluetooth connection is made as an input connection only. If you have further question, please feel welcome to contact our customer help-desk.
