GKD 350H Ultra Quick Look

It’s incredible

The GKD 350H Ultra is a pretty unusual handheld.

It’s an all-metal handheld in the $160 price range, with an absolutely gorgeous 3.5-inch 1600×1440 display, surprisingly incredible speakers, a 5,000mAh battery and a Rocknix-based operating system.

And when I say all metal, I mean all metal.

The dpad is metal, the buttons are metal, the shell is metal — everything about this thing feels like GKD wanted to make a premium handheld.

It’s also a chunky boy.

This thing is thick.

Design and Build Quality

The first thing you’re going to notice is just how substantial the GKD 350H Ultra feels.

The metal construction gives it a premium feel that you don’t normally get in this price range, although it also makes the handheld considerably heavier than a typical plastic device.

The black sections of the device are also extremely fingerprint-prone. I went with the silver version, although the color only changes portions of the exterior, so you’re still going to be wiping fingerprints off this thing regularly.

There’s also an unusual glass section on the back of the device.

I’m still not entirely sure what the purpose of it is. It doesn’t appear to add any functionality, but it does fit with the overall design.

The biggest issue I’ve found with the metal construction is actually the one thing I didn’t expect: there’s a sharp edge on the back.

There’s a small gap where the metal comes together, and when I slide my fingers down while holding the device normally, my fingers can catch on that edge.

I’ve actually scratched my finger on it while using the device.

It’s not something I think everyone will experience, but it’s something I noticed immediately and it’s annoying enough that I’m hoping the TPU case I ordered will solve the problem.

Controls

The dpad and buttons are both made from metal, which is certainly different.

The dpad is actually quite good.

It’s clicky, doesn’t require a huge amount of force and I’ve had no real problems with it. It does bottom out a little more quickly than I’d prefer, but considering what this device is and what it costs, I think it’s perfectly serviceable.

The buttons are also good.

They’re microswitch-style buttons with a little bit of extra resistance, and they’re slightly clicky rather than silent.

They’re also quite large, which I like.

Overall, I don’t think many people are going to have serious complaints about the dpad or buttons. They’re not my favorite controls ever, but they’re good.

The Analog Stick

The stick, on the other hand, is something I could have happily done without.

I don’t think this device needed an analog stick at all.

The stick sticks out quite far and is angled for some reason, and the actual stick cap is extremely slippery. There’s basically nothing to grab onto.

Movement doesn’t feel particularly good either. There’s a grinding sensation when using it, and overall I just don’t enjoy using it.

The good news is that you can remove it.

If you’re buying this primarily for Game Boy, Game Boy Color and Game Boy Advance, I’d honestly rather have the stick gone entirely.

Shoulder Buttons and Triggers

The shoulder buttons are nice and clicky without being particularly loud.

They’re easy to reach and feel good to use.

The L2 and R2 triggers are also relatively quiet and have a nice feel to them.

I don’t have any major complaints about the shoulder controls.

The Screen

This is the reason you buy the GKD 350H Ultra.

The screen is absolutely gorgeous.

It’s a 3.5-inch 1600×1440 display, and as far as I can tell, this is essentially the same type of display we’ve seen in the Analogue Pocket.

I’ve loved the Analogue Pocket’s screen since that handheld launched, and it’s still one of my favorite handheld displays.

Getting something like this in a much cheaper handheld is fantastic.

It honestly looks like an OLED display at first glance.

The resolution is also perfect for the systems this handheld is aimed at.

Game Boy and Game Boy Color look incredible, and the combination of the screen, glass front and black bezels makes the display blend into the device extremely well.

Game Boy and Game Boy Color

This is where the GKD 350H Ultra really shines.

Game Boy and Game Boy Color games look fantastic.

The screen is the standout feature of this handheld, and once you start playing something like Zelda or Adventure Island, it’s immediately obvious why.

The screen doesn’t feel like you’re looking at a small LCD surrounded by a handheld shell.

Instead, the black portions of the display blend into the surrounding glass so well that it can be difficult to tell where the actual screen ends.

For 4:3 content, you can technically change the aspect ratio to 8:7 if you want to take advantage of the Game Boy’s actual display proportions.

Personally, I wouldn’t bother.

The 4:3 presentation looks fantastic here, and the way the display blends into the glass makes it look incredibly clean.

Game Boy Advance

Game Boy Advance looks just as good.

The 3:2 aspect ratio works particularly well with this display, and again, it’s difficult to tell where the actual screen ends.

This is one of those handhelds where you can look at a Game Boy Advance game and it genuinely looks like you’re playing on a modern version of the original hardware.

The screen is easily one of my favorite things about this device.

Performance

Inside the GKD 350H Ultra is an RK3576S processor with 2GB of RAM.

That gives the device enough power for the systems you’d expect from a handheld like this.

Game Boy, Game Boy Color, Game Boy Advance, Super Nintendo and similar systems are obviously no problem.

You also have enough power for systems like Nintendo 64, Dreamcast and PSP, although I wouldn’t buy this handheld specifically for those systems.

The analog stick makes Nintendo 64 technically possible, but that’s not really where this device shines.

For me, this is a premium Game Boy-focused handheld that happens to have enough power to do more.

Rocknix

The GKD 350H Ultra runs a version of Rocknix, which is essentially an EmulationStation-based operating system.

That gives you the usual EmulationStation experience, including scraping, network settings, sound settings, themes and the other options you’d expect.

It’s considerably better than some of the operating systems GKD has used on previous devices.

That said, I don’t love how much it handles outside of RetroArch.

For example, shaders and filters are controlled through the operating system rather than directly inside RetroArch.

If you’re someone who doesn’t like shaders, you’ll need to go into the system settings and turn them off.

Once you do, those settings can apply across your games, although you can also configure things on a per-game basis.

It’s functional, but it’s not my preferred way of handling RetroArch settings.

Internal Storage and RetroArch

There’s 8GB of internal storage, and this actually matters because the operating system is installed there.

The microSD card is essentially where your games live.

You can’t simply plug the internal storage into your computer and start changing files.

To access some of those files, you’ll need to SSH into the device.

That became particularly important for me because RetroArch was set to Chinese out of the box.

I couldn’t find a normal way to change the language across everything, so I had to SSH into the device and manually change the RetroArch configuration.

That’s obviously not something I’d expect the average user to want to do.

I’ve included the instructions separately for anyone who runs into the same problem.

Connect device to internet
Open SSH
nano /storage/.config/retroarch/retroarch.cfg
CTRL+W type user_language
change it to 0 so user_language = "0"
CTRL+O, Enter, CTRL+X
type reboot

Battery and Charging

There’s a 5,000mAh battery inside the GKD 350H Ultra, which is a very welcome addition.

Even better, USB-C to USB-C charging actually works.

This might sound like a ridiculous thing to celebrate in 2026, but we’ve had enough handhelds that refuse to charge properly with standard USB-C chargers that I’m happy whenever one actually follows the USB-C standard.

C-to-C works.

Fast charging works.

You can use normal USB-C cables.

GKD figured it out.

Someone should probably tell Anbernic.

The downside is that the device gets extremely hot while charging, particularly when using faster charging.

It’s not something that has made me concerned about safety, but it’s definitely noticeable.

The device supports up to 18W charging.

Speakers

The speakers might actually be the second-best feature of this handheld.

There are dual AAC sound chamber speakers, and they sound incredible.

I’m not an audiophile and I don’t pretend to understand the technical side of speakers, but I know when something sounds good.

These sound really good.

They’re down-firing speakers, but that doesn’t seem to hurt them.

In fact, these are some of the best speakers I’ve heard on a handheld anywhere near this price.

I’d put them up against handhelds costing considerably more.

Connectivity

You also get Wi-Fi and Bluetooth, which is particularly useful for things like RetroAchievements and syncing your saves.

That’s a big improvement over some of GKD’s older handhelds.

There’s also a 3.5mm headphone jack, and GKD claims this is designed to work with higher-end headphones.

I don’t have the equipment to properly test that, so I can’t really comment on the quality there.

There is also rumble and display output through micro HDMI.

I haven’t tested the HDMI output extensively yet, so I wouldn’t make a buying decision based on that feature.

Comfort and Size

The biggest physical downside is the thickness.

This is a thick handheld.

For comparison, it’s roughly as thick as an RG351P, although the metal construction makes the GKD considerably heavier.

The weight isn’t necessarily uncomfortable, but you definitely know you’re holding a metal handheld.

That makes the device feel premium, but it’s also something you’ll have to decide whether you actually want.

The metal construction is part of what makes the GKD 350H Ultra special, but it’s also part of what makes it so heavy and chunky.

What Is the GKD 350H Ultra Actually For?

This is probably the most important question.

I wouldn’t buy this because you want a Nintendo 64, Dreamcast or PSP handheld.

I wouldn’t buy it because you need an analog stick.

And I definitely wouldn’t buy it because you want the most powerful handheld possible for $160.

You buy this because you want a premium Game Boy handheld with an incredible screen.

That’s where this device makes sense.

The combination of the 1600×1440 display, metal construction, excellent speakers and glass front makes it feel considerably more premium than most handhelds in this price range.

It’s almost like a cheaper version of the Analogue Pocket concept.

And that’s probably the best way I can describe it.

Final Thoughts

The GKD 350H Ultra came completely out of nowhere for me, but I really like it.

There are things I would change.

I don’t think it needs the analog stick.

The stick itself isn’t very good.

The device is extremely thick and heavy.

There’s a sharp edge on the back of my unit that I don’t like.

And I’m still not completely sold on the operating system.

But the things that GKD got right are really good.

The screen is incredible.

The speakers are incredible.

The metal construction gives it a premium feel that you rarely see at this price.

USB-C charging actually works properly.

And Game Boy and Game Boy Color games look absolutely fantastic.

For me, that’s what this device is about.

You don’t buy the GKD 350H Ultra to play everything.

You buy it because you want one of the nicest ways possible to play Game Boy, Game Boy Color and Game Boy Advance without spending Analogue Pocket money.

And for around $160, that’s a pretty compelling package.
