「JBL Quantum」シリーズから待望の完全ワイヤレスイヤホン!欲しい機能全部乗せの「JBL Quantum TWS」発表!

Let's open the package!

The packaging emphasizes the completely wireless nature of the product.
Saiga NAK

The packaging is a cyber-inspired purple color, characteristic of the "JBL Quantum" series.
The two earphones protruding from the charging case emphasize the fact that they are completely wireless.

At the top is the "SOUND IS SURVIVAL" copy, which was also displayed on the JBL Quantum 50.
The JBL Quantum series is designed to outperform the competition.

"JBL Quantum TWS"充電ケース
JBL Quantum TWS charging case
Saiga NAK

The charging case fits in the palm of a woman's hand.
It holds the left and right earbuds and the USB Type-C wireless dongle for 2.4GHz connection.
The earbuds can play wirelessly for up to 24 hours (*depends on usage environment), and if placed in the charging case, charging is completed in about 2 hours from no remaining charge!
Charging to the charging case is possible through the USB Type-C port on the back.

Let's try it for now!

I plugged it in for the time being.
Saiga NAK

I want to use it anyway! Yes!

Unable to suppress my eagerness, I plugged the dongle for 2.4GHz connection into the USB Type-C port of the PS5.
How can I use it just by plugging it in without any initial setup...

Setup screen
Saiga NAK

It works!
The PS5's settings screen clearly shows the words " USB headset (JBL Quantum TWS) "!
Now I can use it as much as I want!

Exit from the setup screen and go to the battlefield!
Saiga NAK

When connected to 2.4GHz, the mode can be changed by tapping the touch area on either the left or right earpiece.
One tap turns on the active noise canceling function, AMBIENT AWARE function on or off, and two taps toggles the TalkThru function on or off, which picks up the voices of those around you.
With the Active Noise Cancellation feature turned on, the sound around you is unnaturally eliminated, forcing you to focus on the footsteps and gunshots in the game!

Applications that extend the sound experience

JBL Quantum TWS is compatible with the JBL QuantumENGINE PC software and the JBL Headphones smartphone app!
Let's try it right away!

JBL QuantumENGINE" PC software

Download "JBL QuantumENGINE" from the JBL Quantum support page, install it, and you are ready to go!
The interface responded when I connected the 2.4GHz dongle to the PC.
From the software screen...

  • Volume
  • Microphone on/off
  • Audio source
  • Battery for earphones and charging case
  • Battery for earphones and charging case

In addition, you can check and change the equalizer and other settings.

JBL QuantumSURROUND" function
Saiga NAK

The " more expansive sound " is the most eye-catching of the available tabs.
Clicking on it brings up the " JBL Quant umSURROUND" function.
The world's first 7.1ch surround sound "JBL QuantumSURROUND", developed by JBL, creates an overwhelming sense of immersion by reproducing space in three dimensions.
The ability to express not only the direction of sound, but also the location of sound, will surely contribute to high performance in game play.
The fact that there is a size setting for head circumference also shows how serious they are...!

Finding the earphones
Saiga NAK

The "System Software" tab allows you to check the "JBL QuantumENGINE" language settings and earphone version, as well as the " Find Earphones " function.
It is sometimes difficult to find the fully wireless earphones if they are dropped in a room.
When you press the play button, the earphones will emit a high-pitched beep to tell you where your lost earphones are.
As noted in the warning, the earphones emit a very loud beep, so please do not use the device with the earphones in place.

The "JBL Headphones" smartphone app can be installed from the App Store andApp Store.
However, Bluetooth connection requires a pairing ritual.
I am sure I am not the only one who has experienced that pairing takes a long time with cheap wireless earphones, and that I have had to repeatedly press the reset button with a toothpick.
But with "JBL Quantum TWS," you don't have to worry about that!
Simply open the charging case and the pairing mode is activated, then select "JBL Quantum TWS" from the smartphone screen for easy pairing!

Test the ear canal! The test of the ear canal takes only about 40 seconds!
Saiga NAK

Easy Setup is activated for the first time!
You can check for the best fit, test your ear canal, and set up the voice assistant to personalize it for you.

In just a few minutes, the entire setup was complete and we were on our way to the settings screen.
"JBL Headphones" allows you to check the battery status of the earphones and charging case, control the ambient sound and equalizer, change modes, and change the language of voice prompts.
The voice prompts can be selected from 11 languages, including Japanese.
I selected Japanese, but due to the polite Japanese, I got the impression that it lacked speed compared to English.
The English prompts are not difficult to understand either, so it seems to be a choice for the user.

Abundant setting options
Saiga NAK

The " Smart Audio & Game " section allows switching between audio mode and game mode.
Audio mode is the highest sound quality setting, while game mode reduces latency to a minimum.
I tried it out and it was obvious (or was it just my ears?) that the latency was reduced in game mode compared to audio mode. It was!
When playing mobile games via Bluetooth, be sure to select game mode!

And one of the best features of the "JBL Quantum TWS" is the simultaneous Bluetooth and 2.4GHz connection!
To switch between Bluetooth and 2.4GHz, just three taps on the touch area of the left earpiece.
Once you get used to it, you can use it very comfortably!
Note that the 2.4GHz side of the Bluetooth connection remains silent while the output device remains connected, and the Bluetooth side of the 2.4GHz connection does not recognize the output device.

All-in-one "JBL Quantum TWS

All-in-one sound system!
Saiga NAK

The sound quality is, of course, perfect! Customizable with dedicated software and apps! Audio output and connection strength are excellent!
The " JBL Quantum TWS " has everything you need!
As of this writing, the JBL Quantum TWS is priced at 18,000 yen (including tax) on Amazon.co.jp. It's not cheap, but that's why we recommend this product to beginners of fully wireless earphones.
Please check the "JBL Quantum TWS" product page for detailed specifications!
