Amazon's limited-time deal drops Sony's 4K Blu-ray player to just $218

Sony has a solid reputation for Blu-ray players, and the X700U model on sale offers many of the features found in some of Sony's high-end Blu-ray player series. It plays 4K Blu-ray at native 4K UHD (2160p) resolution and supports HDR10 for improved image brightness.

It comes with an HDMI cable, but if you don't have a spare, we recommend purchasing an additional 4K cable. This is because the player has two HDMI output ports. The primary output is for video and audio, and is the only output you have to use, but the second output is dedicated to audio. Separating the audio from the video output produces richer, clearer sound, so dual ports are common on dedicated 4K Blu-ray players. This is one of the benefits of using a Blu-ray media player instead of a gaming console like the PS5 or Xbox Series X. Amazon Basics 4K HDMI Cable for less than $5 Now.

The UBP-X700U also features coaxial SPDIF for connecting speakers, soundbars, and TVs. In terms of audio support, the UBP-X700U is equipped with high-end audio enhancements, including Dolby Atmos and DTS:X.

One of the coolest features of a dedicated Blu-ray player like the X700U is image upscaling. The X700U can read 4K Blu-ray, standard Blu-ray and DVD. When enabled, built-in technology will increase the resolution of standard Blu-ray and DVD.

While we haven't tested the 2025 version of the X700U yet, the upgrades from previous iterations are pretty impressive. Standard 1080p Blu-ray discs look very close to 4K resolution, while 480p resolution DVDs look much better. Let's be honest, without upscaling technology, DVDs often look terrible on modern 4K and HD panels. That said, the upscaled output varies, sometimes with jagged edges or obvious oddities that won't appeal to viewers looking for an authentic experience.
