Someone asked owners of 4K Blu-ray players about the reliability of different models over time, and there is a clear winner

Nearly 400 4K Blu-ray users shared information about player issues
There is a huge gap between the best and the worst in the poll
Panasonic will be happy; Sony not so much

One of the things I love most about Reddit is the way people share their experiences with certain products: whether it’s a kitchen knife, a portable AC, or a Gibson guitar, I know I’ll be able to find sage advice on what to buy and what to watch out for. And now the good folks at r/hometheater have come together to talk about the best 4K Blu-ray players and their reliability.

The poll was conducted by r/hometheater poster “requieminadream” and generated nearly 400 responses—nearly double the number of previous poll respondents—from r/4KBluray, r/Bluray, r/PhysicalMediaMatters, the AVS forums, and the Blu-ray.com forums. And there are some very clear differences between different companies’ Blu-ray devices.

Requieminadream very kindly summed up the results in one sentence: “The Sony UBP-X700 is still the problem child, the Panasonic DP-UB820 is still the champion, and the expensive UB-9000 posted the cleanest numbers (albeit a small sample).”

Which 4K Blu-ray players are the best?

One of the reasons I like Reddit wisdom is that, with few exceptions, reviewers can’t spend years with the products they test – so the reviews of my car don’t know about the software problems that drive me crazy and sometimes require a restart at traffic lights, and the reviews of my router don’t know about its tendency to misbehave every few weeks.

It’s the same with Blu-ray players: even the most in-depth review won’t be able to tell you whether a player is likely to pack up in year two or three. (Although an exception is our Panasonic DP-UB820 review, written by our TV Hardware senior writer James Davidson, because he wrote us a fresh review based on combining the use of it in our test room and having used it daily for several years beforehand.)

But in general, polls like this one are a brilliant resource.

By a wide margin, the Panasonic DP-UB820 is the community’s player of choice: 43.4% of respondents have one, and its problem rate was about half that of the Sony UBP-X700. The rate of serious problems was very low, at just 8% – supporting what James had said when he called it “the workhorse of the 4K Blu-ray player world”.

The “problem child” that came out of this latest poll is the Sony UBP-X700. Of the 103 Sony users, about 77.7% reported some problems over time; recurrent and/or severe problems were 23%. The number one complaint is freezing during triple-layer transitions, which is something that has long been discussed on Blu-ray forums.

The measurement shows another interesting pattern, which is problems over time. For Sony, problems became more common over time – but for Panasonic, the pattern of any failures appearing early was better long-term reliability.

The other players in the study fell in between the two extremes, but some of the best results came from “other” players, including game consoles and more niche Blu-ray products.

Satisfaction with these products was exceptionally high, with the PS5 receiving a significantly higher rating than the Xbox. It’s all the more striking given the Sony X700’s performance: the PS5 is a more premium product, and that seems to be reflected in its reliability – unfortunately, we shouldn’t expect more PlayStations to come with a disc player.

I should make it clear, as the original Redditor did, that in some cases the sample sizes for ownership in these polls are quite small, so we should take the results with a grain of salt. However, the Panasonic UB820 and Sony X700 were the best represented and are the two most popular players, so their data is arguably the most useful anyway.
