YOFANQI [6W] コンピュータースピーカー

This article looks at the YOFANQI [6W] コンピュータースピーカー (YOFANQI [6W] Computer Speaker) through its published specs, its review record, and the one design decision that defines it: a single USB-A cable and nothing else. Short version — it is a sensible first step up from laptop or all-in-one built-in speakers, but the USB-only input is simultaneously its biggest limitation.

Overview

The YOFANQI [6W] コンピュータースピーカー draws both power and audio from one USB-A cable. Published figures are 6W maximum output, a 20Hz–20kHz frequency response, and a surround mode.

No AC adapter, no 3.5mm cable — exactly one cable joins your desk.

It suits people who find their built-in speakers muddy: voices that sound boxed in, video effects that collapse into mush. Note that 6W is small next to a 2.0ch bookshelf pair (typically 20W–40W combined), so this will not fill a room.

For nearfield listening at 50–80cm, however, 6W is rarely short on volume.

The Amazon.co.jp listing shows 4.7 out of 5 — a 94% approval rate — across 43 reviews (captured 7 September 2026).

Forty-three reviews is a thin sample, so do not weigh that 4.7 like a premium product's score.

Budget audio tends to be rated "good for the money," and this figure is best read as price-adjusted satisfaction rather than absolute sound quality.

Compatibility Guide

Input is USB-A only: no 3.5mm analog jack, no Bluetooth.

It presents itself as a USB audio device, so Windows, macOS and Chrome OS recognise it without extra drivers. The flip side is that plugging it in does not automatically produce sound — you must select it as the output device in the OS.

Most "my meeting app has no sound" reports come down to the app's own output setting still pointing at the internal speakers.

Bus-powered hubs deserve the most caution. A standard USB-A port supplies 5V/0.5A (2.5W), and even extended profiles reach only around 5V/0.9A.

The 6W figure is almost certainly an amplifier peak rating, which leaves room for distortion or audible cut-outs at high volume when power is tight. Plug straight into the computer where you can; if you must use a hub, use one with its own AC adapter.

On a thin USB-C-only laptop you will add an adapter, which cancels out roughly half of the "one tidy cable" benefit — worth checking your port layout before ordering. The cable is captive and long enough for normal desktop placement.

Because a broken cable means a new speaker rather than a new cable, route it clear of monitor-arm pinch points.

Product Info

Published specs: 6W maximum output, 20Hz–20kHz frequency response, USB-A connection, surround audio mode. Treat the 20Hz–20kHz claim as marketing shorthand.

A 20Hz floor belongs to large subwoofers; a palm-sized cabinet cannot move meaningful air down there. Budget speakers commonly quote a wide range without stating tolerance (±3dB, for instance), so expect usable bass somewhere above the 100Hz region.

Frame it as "a bit more body than a laptop speaker" and you will not be disappointed.

The surround mode most likely widens the stereo image by emphasising channel differences. That helps atmosphere in films and games, but it can smear vocal placement and push the treble toward harshness.

Rather than leaving it on permanently, try it off for music and on for video.

One important note on price. The automatically collected pricing field contains ￥19,980, which is an implausible order of magnitude for a 6W USB-powered speaker and is very likely a data-collection mismatch. For that reason this article quotes no specific price.

Prices also move frequently, so check the current figure on the product page itself. The box contains the speaker only, and its captive USB cable cannot be replaced.

Competing Alternatives

Even within "small USB-powered PC speakers," design intent varies. The deciding question reduces to one thing: is USB-only input enough for you?

• Want more inputs? Models that add a 3.5mm jack alongside USB power can also serve consoles, phones and older PCs.
• Want better sound? Bluetooth bookshelf or gaming models with larger amplifiers and cabinets have far more low-end headroom.
• Mainly for meetings? A speakerphone with a built-in microphone makes more sense. This unit has no mic.

The YOFANQI wins when the constraints are narrow and clear: you do not want extra cables, you have no plans to connect anything but a PC, and you simply want out of built-in-speaker territory. If you suspect you will want to hook up a phone later, buy something with a 3.5mm input now and skip the second purchase.

What to Expect in Use

At this level the biggest perceptible change is not music — it is speech. Thin laptop cabinets lose the lower midrange, which is exactly where voice intelligibility lives.

Moving to any external speaker sharpens vocal outlines and makes long meetings less tiring. That easily-noticed improvement is probably a large part of why 43 reviewers landed on 4.7.

What you should not expect is imaging or detail. With the drivers sitting close together, stereo width is physically limited.

This is not a tool for judging footstep direction in an FPS or for evaluating a mix; leave that to headphones.

Points to Check Before Buying

1. No 3.5mm, no Bluetooth. Treat it as PC-only.

Console and phone use is not documented by the maker, so look elsewhere if that matters.

2. No built-in microphone. This is the most common misunderstanding among remote-work buyers.

You will still need a mic or headset for calls.

3. Check both volume controls. USB audio devices often have a hardware knob independent of the OS mixer.

If it sounds quiet, check the OS output level and the app level before assuming a fault.

4. The cable is captive. A break ends the product's life, so keep it away from desk edges and drawers.

5. Listing data can disagree with itself. As noted, the price field held a figure (￥19,980) out of step with the product class, and the seller and shipper are listed as "PIXVOR Official Store JP" rather than YOFANQI.

Reseller arrangements like that are normal, but marketplace listings do sometimes carry mismatched metadata. Before buying, confirm that the images, title and spec table on the product page agree with each other, and trust the page's price over any figure in an article.

6. Only 43 reviews so far. A 94% approval rate (captured 7 September 2026) is good, but small samples move easily and give little insight into defect rates.

Check that both drivers produce sound soon after delivery.

Best Use Cases

• Anyone unhappy with laptop built-in speakers — plug in, switch the output device, and voices and video sound clearer. 6W is plenty at desk distance.
• Anyone minimising desk cabling — no AC adapter, one cable, and a cabinet small enough to sit under a monitor.
• Anyone wanting a cheap first upgrade — it does the job, and moving up later costs you little.
• Home-office users watching video and joining calls — with a separate microphone.

Who should skip it is equally clear: bass lovers, gamers who need positional audio, anyone connecting non-PC devices, and anyone judging sound for music or video production. In those cases look at a 20W-plus model with 3.5mm or Bluetooth input, or monitoring headphones.

FAQ

Q. Does it work the moment I plug in the USB cable? A.

It is detected, but you must select it as the output device in the OS sound settings — and separately inside conferencing apps.

Q. Can I connect it with a 3.5mm cable?
A. No. USB-A is the only input; there is no analog jack.

Q. Will it work with a phone or a PS5? A.

Not recommended, since the maker does not state support. Phones expect 3.5mm or Bluetooth, and this unit has neither.

Q. Can I use a USB hub? A.

A self-powered hub with its own AC adapter is generally fine. Bus-powered hubs risk dropouts and low volume, so a direct port on the computer is safest.

Q. Is there a microphone?
A. No. Calls require a separate microphone or headset.

Q. Is 6W loud enough?
A. For nearfield desk listening, yes. For filling a large room or a gathering, no.
