The Sony BRAVIA 3 S35B K50S35B is a 50-inch 4K Ultra HD smart TV aimed at households that want a cinematic picture and strong streaming options without stepping into flagship OLED territory. With Sony’s trusted picture processing and a solid feature set, it’s designed as a capable all-rounder for everyday viewing and movie nights alike.
Sony’s X1 processor, XR Triluminos Pro colour system and support for Dolby Vision and Dolby Atmos put it a notch above many basic 4K sets, while Android TV with Chromecast built in keeps things flexible on the smart side. User reviews are very positive, with a 4.8 out of 5 rating from around 30 owners, suggesting picture quality and ease of use live up to expectations.
Priced in the mid to upper mid range for a 50-inch LED TV, it’s not the cheapest option, but you are paying for Sony’s processing, broad app support and a future-proof selection of smart features.
This 50-inch BRAVIA 3 is ideal for a main living-room TV in flats, terraced homes or family lounges where you sit a couple of metres from the screen. The 4K resolution and Sony’s upscaling tech mean HD broadcasts, streaming and older content all look crisp on a screen this size.
It suits buyers with a mid-range budget who want a clear step up from basic supermarket 4K sets but don’t feel the need to stretch to OLED or mini-LED prices. If you watch a lot of films and premium streaming content, the combination of 4K, Dolby Vision and Triluminos colour will be particularly appealing.
Thanks to Android TV, built-in Chromecast, Apple AirPlay 2 and support for Alexa, Google Assistant and Apple HomeKit, it’s a good fit for anyone already invested in a smart home ecosystem. It’s also an easy recommendation for first-time 4K TV buyers who want something straightforward to use but don’t want to compromise on picture quality.
Casual console gamers will be happy enough with the dedicated gaming menu and Auto HDR tone mapping, but if you’re a serious competitive gamer chasing ultra-high refresh rates, you may want to look at a 120Hz set instead of this 50Hz panel.
Picture quality is the star here. The 4K Ultra HD panel, driven by Sony’s X1 processor and X-Reality PRO upscaling, delivers sharp, detailed images, even when you’re watching HD or streamed content that isn’t natively 4K. XR Triluminos Pro brings a wide, natural-looking colour palette that really benefits films and high-quality streaming.
Support for Dolby Vision and HDR streaming across major apps such as Netflix, Disney+, Prime Video and Apple TV means you can actually see the extra contrast and colour depth from modern content. Dolby Atmos support and the X-Balanced Speaker design give sound a bit more weight and clarity than many slim TVs manage, so you’re not forced into buying a soundbar straight away.
On the smart side, Android TV (with a Google TV-style experience) offers a huge range of apps along with built-in Chromecast, Apple AirPlay 2 and Miracast. That makes it very easy to get content onto the screen from Android phones, iPhones, tablets and laptops. Voice control via Google Assistant plus compatibility with Alexa and HomeKit adds flexibility.
Everyday convenience is strong too. There are four HDMI ports and four USB ports, so you can hook up consoles, set-top boxes, sound systems and storage without constantly swapping cables. Features like Ambient Optimisation, Eco Dashboard, auto power off and a sleep timer help tailor the viewing and keep an eye on energy use.
The main compromise is that this is a 50Hz panel, so while it’s absolutely fine for TV, films and casual gaming, motion may not look as smooth as on higher-refresh models, especially if you’re a keen gamer with next-gen consoles.
The energy rating is E, which is fairly typical for modern 4K TVs but not outstanding. If you watch a lot of TV every day and are trying to keep electricity bills down, that’s worth bearing in mind, even though there is an Eco Dashboard and energy-saving modes.
The manufacturer warranty is only one year, which feels a little short for a TV at this price point. You may want to factor in the cost of extended cover for peace of mind.
Finally, while the direct-lit LED panel is capable, it won’t match the deep blacks and contrast of more expensive OLED or high-end local-dimming sets. Movie enthusiasts with dark-room setups might find those technologies more appealing if budget allows.
Living with the Sony BRAVIA 3 S35B is largely hassle-free. At 50 inches with a slim 7 cm depth, it’s a practical size for most media units and wall mounts, and the simple legs stand keeps it stable on a TV bench. VESA wall-mount support gives you the option to get it up on the wall for a cleaner look.
Android TV is intuitive once set up: you get a clean, app-first home screen with quick access to Netflix, Disney+, ITVX, Now, YouTube and more. Built-in Chromecast and AirPlay 2 mean casting from your phone is as simple as tapping an icon, while Screen Mirroring and Miracast cover Windows and Android devices.
Voice control makes everyday navigation easier. Being able to search for a programme, open an app or adjust settings via Google Assistant, or link the TV into an Alexa or Apple HomeKit setup, cuts down on remote fiddling. Features like Smart Voice Search and the dedicated gaming menu keep common tasks just a few clicks away.
For longer sessions, the combination of Ambient Optimisation and auto power off helps keep things comfortable and efficient. Brightness and sound adapt to your room conditions, while sleep timers and eco modes mean you’re less likely to leave the TV blazing away needlessly if you nod off mid-boxset.
Core performance is anchored by the 4K Ultra HD resolution (3840 x 2160) and direct-lit LED panel. Sony’s X1 processor does the heavy lifting, analysing each frame to sharpen detail, clean up noise and upscale lower-resolution content, so even standard HD broadcasts gain a bit of polish.
XR Triluminos Pro is Sony’s colour technology, and it shows in a wide, believable colour range without the cartoonish oversaturation some sets fall into. HDR support, including Dolby Vision, lets the TV take advantage of premium content from Netflix, Disney+ and other major platforms, serving brighter highlights and better contrast.
Motionflow XR aims to keep fast action smoother on the 50 Hz panel, which is helpful for sport and action films. It won’t transform the TV into a high-refresh gaming monitor, but it does reduce blur and judder compared with very basic sets. For gamers, the gaming menu and Auto HDR Tone Mapping with compatible consoles make it easier to get a good-looking picture without diving deep into settings.
On the audio side, the X-Balanced Speaker configuration and Dolby Atmos support deliver cleaner dialogue and a more immersive soundstage than many entry-level TVs can offer. While a dedicated soundbar will still outperform it, this TV holds its own for everyday shows and films.
Smart features are comprehensive. Android TV with Google TV-style interface, Chromecast Built-In, Apple AirPlay 2, Miracast, Screen Mirroring, and voice control cover almost every way you might want to get content on screen. Music apps such as Spotify and Amazon Music, plus a full suite of video services from Netflix and Prime Video through to Paramount+ and YouTube, make it a strong hub for all your entertainment. Four HDMI and four USB ports, USB recording (PVR) and a digital tuner round out a very complete feature set for a 50-inch LED TV.
At around £699, this Sony BRAVIA 3 S35B sits in the mid to upper mid range for 50-inch LED TVs. It’s not a budget option, but you are getting a specification and brand pedigree that go beyond cheaper supermarket models.
The inclusion of Sony’s X1 processor, XR Triluminos Pro, Dolby Vision, Dolby Atmos, broad app support, plus four HDMI and four USB ports all add value. Many similarly priced sets offer fewer connectivity options or less sophisticated picture processing.
The 4.8/5 owner rating is a strong indicator that buyers feel they’re getting what they paid for, or better. The main value considerations are the 50 Hz refresh rate and one-year warranty, which stop it being an outright bargain. Even so, for someone who prioritises picture quality, smart features and brand reliability over bleeding-edge gaming specs, it represents good value.
The Sony BRAVIA 3 S35B 50″ 4K Ultra HD Smart Android TV is a well-rounded, feature-rich option for households that want a high-quality main TV without moving into more expensive OLED territory. Strong 4K performance, excellent colour, Dolby Vision and Dolby Atmos support, and an extensive smart platform mean films, TV and streaming all look and sound very respectable.
It does have a few caveats: the 50 Hz panel isn’t ideal for serious competitive gamers, the energy rating is only average, and the one-year warranty is on the short side for a TV at this price. If those points are deal-breakers, it’s worth considering alternatives with 120 Hz panels or longer guarantees.
For most people, though—especially film fans, boxset binge-watchers and households that rely heavily on streaming apps—the BRAVIA 3 S35B strikes a strong balance of performance, features and everyday usability. It’s a confident choice if you’re after a premium-feeling 50-inch 4K TV from a trusted brand.
