How to Sync the U.F.O. TW with VR Headsets, Phones and PCs

Here's how to sync the U.F.O. TW with each of these devices, with screenshots:

Phones
PCs

I also share the Adult Festa videos I actually bought that sync with the U.F.O. TW (Adult Festa is a Japanese VR video site).
Fair warning: they're insanely cute and insanely hot.

Here's how to sync it with DLsite audio works using CSV files:

I also cover what to do when it won't sync, how to find synced titles, and how to buy them.

Be careful: some VR headsets can't sync with the U.F.O. TW.

Even so, I explain how I managed to sync one anyway.

Can You Use the U.F.O. TW Without Syncing?

Yes. Even without syncing, you can use the U.F.O. TW with its buttons.

Here's my article on exactly how to use it (the controls):

VR Headsets That Sync with the U.F.O. TW: Only the DPVR Series (in 2023)

DPVR headsets sync, but the SKYWORTH PRO headset doesn't, so be careful.
On this site I also explain a trick to fake the sync.

When I wrote this in March 2023, the only VR headsets that synced with the U.F.O. TW were the DPVR series. As of September 2026, Adult Festa's newer 4DMEDIAPLAYER+ app also works with Meta Quest: the Quest connects to your phone over Wi-Fi, and the U.F.O. TW connects to the phone over Bluetooth.

NLS (the official Japanese online store for RENDS/VORZE) has a video showing how to use it.

First, log in to Adult Festa and bring up the video you bought.

Press the Bluetooth button to start pairing with the U.F.O. TW.

Note that while it's synced, you can't change the U.F.O. TW's mode or use its other controls.

Even while it's synced, you can force it to stop by holding down the power button.

You can also sync one cup first and then turn on the other one — both cups will still sync.

[Not Officially Possible] A Trick for Syncing with the SKYWORTH PRO

The “SKYWORTH PRO 4DPRO-802” can't sync with the U.F.O. TW directly, but the U.F.O. TW does sync with 4D Media Player on a phone or PC.

So the trick is to start the same video at the same moment on your phone (synced with the U.F.O. TW) and on the SKYWORTH PRO headset — then you can enjoy the sync while watching in the headset.

I explain how to sync with a phone in the next section.

But when I actually tried it, starting both at exactly the same moment was harder than I expected.

If the stream pauses to buffer, the timing drifts, so it's better to download the video onto the VR headset itself.

Lining them up in the middle of a video is hard, but lining them up from the very start was pretty easy.

How to Sync the U.F.O. TW with 4D Media Player on a Phone

Search Google Play for “4DmediaPlayer” and install it. (As of September 2026, Adult Festa also offers the newer 4DMEDIAPLAYER+ app; in it you connect from Bluetooth in Settings, or from the connect-device button on the playback screen.)

Open 4D Media Player. To log in with your Adult Festa account, tap here ↓↓

↓ Tap here and enter your Adult Festa login ID and password.

Your Adult Festa purchases will then show up.

Once your phone and U.F.O. TW are synced, you can also enjoy it with a phone VR headset.

Tap Settings. ↓↓

Tap “Bluetooth.” ↓

Turn on the U.F.O. TW and the sync is set up.

Note: don't pair it from your phone's own Bluetooth settings — set up the connection from inside the 4D Media Player app.

At first I paired it from my phone's Bluetooth settings, and it wouldn't sync.

If it won't sync, unpair it and connect from the app instead.

Also note that the sync pauses while you're using 4D Media Player's controls ↓↓

It doesn't sync while the control screen is showing, but that doesn't mean it's broken.

If you leave it alone for a while, the controls disappear and the sync starts.

Or tap an empty spot on the screen to hide them.

How to Sync the U.F.O. TW with the Player on a PC

The advantage of syncing the U.F.O. TW with a PC is that you can enjoy it on a big screen.
The steps are almost the same as on a phone.

You'll need to install 4D Media Player on your PC.

I explain exactly how to install it here:

Open 4D Media Player and log in with your Adult Festa account.

The 4D MEDIA PLAYER login screen on a PC — Screenshot of 4D MEDIA PLAYER on a PC (in Japanese), March 2023.

Press the Settings button and open the Bluetooth settings.

Click “AF all-you-can-watch” or “Purchased” and play a U.F.O. TW synced video, and it syncs.

Note: for some reason 4D Media Player sometimes won't start, so keep trying — restart your PC if you need to — until it opens.

What to Do When the U.F.O. TW Won't Sync

Is it wrong that both cups make the same movement?

It's normal for the U.F.O. TW's left and right cups to make the same movement.

That's how it's designed, so nothing is wrong.

Because of that, in synced videos both cups move even when only one nipple is being teased.

Turn off your PC, phone or anything else that uses Bluetooth

It may be interfering with other Bluetooth devices.
Just turning Bluetooth off and on again may fix it and get it syncing.

Adult Festa's official site has a note saying the same thing.

Check whether your device can sync with the U.F.O. TW at all

The SKYWORTH PRO VR headset can't sync with the U.F.O. TW (still true as of September 2026).

What to do when only one cup syncs

When I synced the U.F.O. TW with 4D Media Player on my PC, for some reason only one cup rotated.

To be precise, the faulty one just ticked along slowly, like the second hand of a clock.

At first I thought the U.F.O. TW itself was the problem.

But with 4D Media Player on my phone, both cups synced fine.

So I could tell the device itself wasn't the problem.

If you have a DPVR headset, try syncing with it to narrow down the cause.

If you have another PC, install 4D Player on it and see whether it syncs there.

That way you can pin down what's wrong.

It could also be a problem with a particular video, so try buying a different one and see whether it syncs.

How to Find and Buy U.F.O. TW Synced VR Videos on Adult Festa

I emailed Adult Festa to confirm that videos listed only as “UFOSA” in the synced-video section also sync with the U.F.O. TW.

Adult Festa support's email reply about UFOSA-synced titles and the U.F.O. TW — Screenshot of Adult Festa support's email (in Japanese), June 2022: titles marked "UFOSA" also sync with the U.F.O. TW when played in 4DMediaPlayer or on the DPVR-4D Pro / DPVR-4D.

There's “Adult Festa TV” and “Adult Festa VR.”

When I wrote this, the synced titles were on “Adult Festa VR,” so watch out for that. (As of September 2026, Adult Festa also sells U.F.O. TW sets that come with a 2D video.)

Note: there were no titles that sync with both the U.F.O. TW and the A10 Cyclone SA at the same time (as of March 2023).

Finding synced videos on a PC

Click “UFOSA” under “Find synced videos,” and the U.F.O. TW synced titles are listed.

The Adult Festa TV top page with the link to Adult Festa VR highlighted — Screenshot of Adult Festa TV (in Japanese), March 2023.

Just to be safe, check that the synced-goods field says “UFOSA” before you buy. ↓↓

Some titles have reviews saying “it wouldn't sync,” so those are worth checking too.

Then again, whether it syncs depends on each person's device and setup, so it's hard to say for sure.

Finding synced videos on a phone

Tap the search button.

If you don't want to use a credit card, you could also pay with PayPay (a Japanese mobile payment app) through BitCash (prepaid e-money).
I explain how in the second half of this article:

How to Sync the U.F.O. TW with DLsite Audio

Personally, I like syncing it with audio works even more than with VR videos.

There are more audio works than VR videos to choose from.

If you haven't tried it, you're missing out…

Here's my article on syncing it with audio, using files made by fans:

[Insanely Cute] Recommended Adult Festa Videos That Sync with the U.F.O. TW

A still from the recommended VR video: a smiling young woman

For nipple-play synced titles, by far the cutest is the amateur-looking girl in this video.
It was the first title I bought for the U.F.O. TW.

If you like natural, amateur-looking girls, you can't go wrong with this one.

I can't tell whether she's really an amateur, but she's not a face you often see among AV actresses.

“So you like having your nipples licked, huh?”
“You're getting hard. But you have to stroke it yourself, okay?”

She talks like that, slow and sticky, and it hit the spot perfectly.
She doesn't strip, but you catch glimpses of her nipples, which is irresistible.

It was pricey at over ¥1,000 for 10 minutes (March 2023), but it's worth every yen ↓↓

Mikako Abe and Noa Eikawa

I bought this U.F.O. TW synced title for ¥780 (March 2023).

They're both petite and super cute.

Obviously, their skin is gorgeous…

It's an SOD (Soft On Demand) title, an hour and a half long, and they tease you with dirty talk and make sure you finish.

At first they roll your nipples around and make you come with a handjob.

Since it's a nipple-sync title, one of them is always playing with your nipples.

It doesn't sync with the A10 Piston SA, so I ran that one with its buttons.

Here's the video ↓↓
