The sentence that decides this purchase
“4K Upscaling: … 4K Ultra HD discs are not supported.”
That is Sony’s own bullet, on a four-hundred-dollar player whose title leads with 4K.
The distinction is the most important one on this shelf. Upscaling takes a 1080p image and stretches it to fill a 4K screen — every player here does it, and so does every 4K television, generally just as well. Ultra HD Blu-ray is a physically different disc carrying a genuinely 4K image with roughly four times the picture information, and HDR.
So the title is accurate and invites exactly the wrong conclusion.
And the comparison is within the same brand:
Sony UBP-X700U — $328 — “the unrivalled visual clarity of 4K Ultra HD Blu-ray”, 4K upscaling to 60p, HDR, dual HDMI outputs, HDMI cable included
Sony BDP-S6700 — $399.99 — 1080p discs, 4K upscaling, no 4K disc support, Wi-Fi and apps, no cable stated
Seventy-two dollars more for a player that cannot read the disc format in its own title.
What you are actually paying for
The feature list is genuinely the broadest on this shelf, and two items are unique:
Bluetooth output. The player can send sound straight to wireless headphones or a speaker. Nothing else here does it, and for watching late at night without disturbing a house it is the simplest answer available.
Miracast screen mirroring. An Android phone’s screen on the television, with no cable and no app.
Plus Wi-Fi and Ethernet, DLNA home sharing, SongPal multi-room, a coaxial output for an amplifier without HDMI, and 3D.
But the apps are the part that dies first
Streaming on a disc player depends on certificates, DRM renewals and interface changes the manufacturer has to keep shipping. That support ends years before the laser wears out.
The proof is two listings away on this shelf. Sony’s All Region Free model still advertises “the Sony Entertainment Network… Netflix, Pandora, Hulu Plus, and YouTube” — and neither Hulu Plus nor the Sony Entertainment Network exists under those names any more.
A streaming stick costs twenty to fifty dollars, updates continuously, and can be replaced by itself when it stops being supported. A player’s app platform cannot.
Buy the player for discs. Let something else do the apps.
The weight is exactly two pounds
907 g. And the N-NUTROMO Audio on this shelf is also listed at 907 g.
Two unrelated products carrying the same round imperial figure is the mark of a placeholder rather than a measurement. The others here read like measurements: Sony UBP-X700U 3.1 lb (1.4 kg) · Sony BDP-S1700U 816 g (28.8 oz) · Panasonic DMP-BD84P 771 g (27.2 oz) · Panasonic UB420 3.1 lb (1.4 kg) · Panasonic UB820 5.3 lb (2.4 kg).
What is not published
No HDMI cable, where both cheap Sonys and the 4K UBP-X700U include one.
No dual HDMI, which the UBP-X700U and both Panasonics have — and which is how you feed audio to an amplifier that cannot pass 4K video.
No region code, where nine players on this shelf publish one.
No HDR format, which follows: without 4K disc playback there is no HDR to support.
