USB-powered stereo speakers for business desktops

The HP USB Business Speakers v2 connect through a single USB port and draw power from the host device. They deliver 2.0-channel stereo output with a maximum power rating of 5 watts. The compact tower design suits office desks where a simple plug-and-play audio upgrade is needed.

Touch controls and single-cable simplicity

Volume and mute are handled by touch-sensitive controls on the speaker body, removing the need for a separate knob or remote. Because audio and power share the same USB connection, there is no external power brick and no battery to manage. The package contains one speaker unit weighing 550 grams.

5-watt maximum output power

The single specification that determines suitability is the 5-watt peak output. This level is adequate for conference calls, system alerts and background music at typical desk distances. It will not fill a meeting room or provide high-SPL playback for media editing or entertainment.

Questions about this item

Will the USB cable or the touch controls on the N3R89AA need replacing after heavy daily use?

The speaker draws power and audio over a single USB connection and uses touch controls; no user-serviceable parts are listed, so cable or control wear would require full unit replacement.

What limits output first during long sessions — the 5-watt peak rating or the 2-watt continuous rating?

The 2-watt continuous rating is the sustained ceiling; the 5-watt peak is only momentary, so thermal protection will throttle output back to 2 watts during extended playback.

How much heat or fan noise does the N3R89AA produce when running all day from a laptop USB port?

The unit has no fan and draws at most 2 watts continuously, so it stays barely warm and completely silent even after hours of operation.
