Connection issues - including problems with the HDMI port, deterioration of sound quality and faulty remote controls - are the most common sound bar problems, according to our research. Shockingly, 9% of owners said their sound bar just stopped working, with no indication of the cause.
Each year we send out our unique reliability survey, asking customers to tell us why they're pleased with their sound bar, and whether they have experienced problems. In our latest analysis, we've looked at the performance of the biggest sound bar brands, including Canton, LG, Samsung, Sonos and Sony. We've calculated a reliability rating for each, so you know which sound bar brand will be music to your ears for the longest, and which fall flat.
Average score in our sound bar tests
Customer satisfaction score
While sound bars don't have a huge variation in reliability, compared to some tech products, it's still important to choose the right brand. The brand rated as the most reliable by users had an impressive 94% rating, while the least reliable only reached 82%.
The table below summarises this year's reliability results. Brands are ranked by their customer score, which relates to whether their customers would recommend them. The more stars for reliability, the fewer problems reported.
Table notes: The above data is based on a survey conducted on 1,734 Which? members, June-July 2019
The top two most common sound bar faults were problems with the audio connection, and problems with the remote control - 14% of users had experienced these annoying issues. 13% of users had experienced a deterioration in sound quality.
A faulty connection could be anything from mildly annoying (on a port you don't use, for instance), to catastrophic (the only audio connection breaks).
Deterioration of sound quality can be caused by a number of factors, including faulty connections. If you've been listening at extremely high volumes, the speaker cones may have blown. It's also possible that you may have changed the audio settings, and that this has changed the sound quality - try doing a factory reset to see whether this improves things.
Other problems users had experienced included faults with the wi-fi or Bluetooth connection (8% and 7%), soundbars powering down (7%) and issues with the smartphone app, either technical (3%) or after an update (2%). A shocking 9% of users told us that their sound bar had stopped working completely, without explanation.

Our reliability surveys, combined with our extensive lab tests, mean we can recommend the best sound bar for you.
