Pioneer will release the TQ-PG400, a portable gaming speaker that attaches directly to a Nintendo Switch 2 or a smartphone, in mid-September. It is the newest addition to Pioneer's SOUND TECTOR gaming speaker series and comes in two versions: the black TQ-PG400K and the white TQ-PG400WB. Pricing is open, with an expected street price of around 12,000 yen. The speaker deliberately skips an internal battery and draws power from the console instead.
A battery-free design that finishes setup in one step
The TQ-PG400 clamps onto the bottom of a handheld console or a smartphone. Plugging the USB Type-C connector on its front face into the device is the entire setup process.
The absence of a battery is the interesting part. Because the speaker draws power directly from the connected console or phone, there is nothing to recharge on the speaker side and no risk of finding it dead when you want to play. There is no pairing step either. In an era where wireless speakers are the default, choosing a wired, battery-free approach reflects a plain reading of how handheld consoles are actually used.
The trade-off is that the speaker shares the host device's power, which affects console runtime. Pioneer's answer is a dedicated charging USB Type-C port on the side of the unit. Connect a cable there and you can charge the console or phone while playing. The same setup works as a charging stand for watching video.
Dirac signal processing and the WIDE mode
The sound comes from a combination of Pioneer's own acoustic engineering, built up over decades of speaker development, and audio signal processing technology from Sweden's Dirac Research AB. The Dirac processing is aimed at improving vocal clarity and intelligibility, allowing a small dynamic driver to deliver sound with defined edges.
The other pillar is the WIDE mode. This is crosstalk cancellation processing that suppresses sound from each speaker reaching the opposite ear, maximizing the stereo effect and widening the soundstage. With a body only 120mm wide, there is no physical room to separate the drivers, so the width has to be created through signal processing. For players who care about locating footsteps and ambient cues in a game, this is likely the feature that decides how useful the product feels.
The driver is a 13mm by 34mm rectangular unit, a shape that fits a tall opening into the limited front panel area.
160g, usable handheld or on a desk
The unit weighs 160g. That figure is set for holding the console with the speaker attached, keeping the combined weight with a Switch 2 from becoming unwieldy.
A stand on the back offers two angle positions, so the speaker also works for desktop viewing. Being able to switch between handheld and desktop styles is a basic requirement for a handheld console accessory.
External dimensions are 120mm wide, 143mm tall and 37mm deep. Two each of terminal guides A and B are included, parts that stabilize the mounting position across devices with different connector surroundings.
Compatible with Switch 2 and USB Type-C phones
Supported devices are the Nintendo Switch, the Nintendo Switch 2, and smartphones with a USB Type-C port. Pioneer states explicitly that the Switch Lite and Pimax Portal are not supported, so it is worth checking your device before buying.

Summary
The TQ-PG400 is a 160g portable gaming speaker that clips onto a Switch 2 or a smartphone. Its battery-free design removes both pairing and charging from the equation, and a dedicated charging port on the side lets you power the console while you play. Sound relies on Dirac Research AB signal processing and the crosstalk-cancelling WIDE mode to create a wide soundstage from a small enclosure. It ships in mid-September at an expected street price of around 12,000 yen, making it a genuinely interesting option for anyone who wants handheld game audio without wearing earphones.
