Overview

The Buffalo BSSP105UBK is a compact pair of desktop speakers built for people who want better sound without adding clutter. Power comes from a USB port, while audio arrives through a 3.5mm stereo mini plug, so there is no separate AC adapter to find room for. That makes it a natural fit for laptop users and for desks where power outlets are already spoken for.
Each cabinet measures 64 x 72 x 60mm and weighs roughly 210g, so the pair takes up very little desk space. The drivers are 50mm units with a practical maximum output of 3.6W (1.8W plus 1.8W), and the rated frequency range runs from 90Hz to 18000Hz. A wired volume controller sits within reach, letting you adjust levels without leaving whatever is on screen.
At around 1,000 yen, this is an entry-level product rather than a hi-fi statement. It is the kind of purchase you make when the built-in speakers on your machine have started to feel limiting and you want a low-risk upgrade.

Connectivity & Compatibility

The BSSP105UBK is intended for computers and AV equipment that have both a 3.5mm stereo mini jack and a USB Type-A port. Audio travels over the 3.5mm plug, while the USB connection supplies power only. Both cables must be connected for sound to come out, which is the single most important thing to understand before buying.
If the source device has no USB port, you can power the speakers from a USB charger instead. Total cable length is about 1.2m, split into 50cm between the speaker and the controller and 70cm between the controller and the plug. That layout suits placing the speakers on either side of a monitor with the controller pulled toward the keyboard.
Operating voltage is 5V and maximum power consumption is 5.9W. Speaker impedance is 4Ω. There is no Bluetooth or other wireless option here; this is a wired-only design.

Product Info

The BSSP105UBK launched on November 8, 2019 and has remained on sale since, which says something about how well the formula works.Check the retailer's page for the latest price. The warranty period is six months.
Compared with larger powered speakers, output and frequency range are modest. In exchange you get a small footprint and minimal cabling. It is positioned for everyday desk work rather than music production or serious movie watching.

Best Use Cases

  • Laptop owners tired of thin built-in audio: USB power means no outlet hunt, and a single 3.5mm plug gets you sound. Skip it if you want deep bass.
  • Remote workers who need clearer meeting audio: the inline controller makes volume changes quick without touching the screen. Not for filling a room at high volume.
  • Anyone adding minimal sound to a secondary or backup desk: the 64 x 72 x 60mm cabinets fit almost anywhere. Not a fit for surround setups.
