Best Blu-ray and 4K Blu-ray players Buying Guide: Welcome to What Hi-Fi?'s round-up of the best Blu-ray and 4K Blu-ray players you can buy in 2021.
Let's face it, Blu-ray discs provide an amazing improvement to picture and sound quality over standard DVDs.
But, if you up the ante with the  4K Blu-rays, you not only get extra resolution, you also get HDR (including Dolby Vision and HDR10+), and object-based surround formats such as Dolby Atmos and DTS:X. There are tons of 4K discs to choose from, so now is a great time to upgrade on a 4K Blu-ray player, and in our experience, picture and sound quality tend to be better than watching a 4K equivalent on Amazon Prime Video or Netflix.
4K players still spin normal Blu-rays and DVDs (remember them?) so there are no problems with backward compatibility. Some 4K players are also universal decks that can play more niche audio disc formats such as SACD and DVD-Audio.
Our pick of the best Blu-ray players and 4K Blu-ray players all serve up brilliant picture and sound at their respective price points. Here's our definitive list.
With the DP-UB820EB, Panasonic has taken the video processing tech out of the flagship DP-UB9000 – which features further down this list – and placed it it in a more affordable package. And the results are sensational. The player serves up a wonderfully inviting and immersive picture, bursting with colour and detail. It also produces a meaty and exciting sound, which complements the picture perfectly.
All the main flavours of HDR are supported, including HDR10, HDR10+ and Dolby Vision, which means you can extract the most from 4K content. It's a very good upscaler too, so normal Blu-rays should look the part on your shiny new 4K TV. For the money, you'll struggle to find a better all-round machine, which is why we've placed this What Hi-Fi? Award-winner at the top of our list of the best Blu-ray players.

If you want an affordable route into the world of 4K Blu-ray players, the Sony UBP-X700 is a great option. It's one of the most talented 4K players we've seen at this kind of money. It’s a fun, involving performance - pictures are stacked with detail. The Sony displays a wonderfully subtle picture that’s impeccably judged while being hugely entertaining. Sound quality is equally stirring with its zippy, dynamic character complementing that class-leading picture.
The Sony ticks most of the boxes you'd expect a player to at this price, and includes both Dolby Vision and HDR10 support but no HDR10+.
Despite not flashing the hi-res audio badge, the X700 can also play up to 24bit/192kHz files and supports a number of formats, including WAV, FLAC and DSD. There's also smart functionality and twin HDMI outputs. This Sony machine is good enough to boost all manner of home cinema systems, so you can buy with confidence.

This mid-range Sony is a bit more capable – and a bit more expensive – than those at the budget end of the market. While it lacks a display on the player itself, its feature set more than makes up for it. It even has Bluetooth, for streaming audio to a pair of wireless headphones – a godsend for late-night viewing.
There's no HDR10+ support, but otherwise it's a very versatile player, playing nice with such niche audio formats as DVD-Audio and SACD. You have to manually enable Dolby Vision for supported content, which is a bit annoying (it should just happen automatically), but this player's superb performance still makes it easy to recommend.

There's no shortage of excellent 4K Blu-ray players to choose from at the premium end of the market, and the UBP-X1100ES also deserves to be on the list. It's a universal deck which means it can handle all manner of disc formats, including 3D Blu-ray, SACD and DVD-Audio. It supports HDR10 and Dolby Vision HDR, but there's no support for HDR10+, which is a little disappointing.
Its picture is anything but, though. The Sony serves up a balanced, natural and nuanced image, which displays great depth and an impressive amount of detail. It's a musical player too, with excellent timing and a fine sense of rhythm with music and movies alike.

There are some great budget 4K Blu-ray players in this list, but the Panasonic DP-UB9000 is the one to audition if you're in the market for a premium machine.
Its menu system is a little overcomplicated, but once you've got the Panasonic set up for your particular display, it serves up an entertaining and attention-grabbing image, bursting with colour. There's a great sense of depth and realism to 4K images that makes you sit up and take notice.
Soundtracks are delivered with plenty of weight and power, which is just what you want from a premium player like this. It has been bettered for outright musical ability, but the Panasonic DP-UB9000 is still well worth auditioning.
