Lenovo ThinkVision MS30 4 W RMS Soundbar
The Lenovo ThinkVision MS30 is a 4 W RMS soundbar designed for ThinkVision P and T Series monitors. It draws power and audio through a single USB-A connection and includes a security lock to deter physical theft. The compact bar suits professionals who need clear front-facing audio for virtual meetings and online classes without extra cables.
USB 2.0 interface limits cable length and power
The speaker requires a USB 2.0 port that can supply 5 V at 1.6 A, so very long or unpowered hub cables may starve the unit. Frequency response spans 140 Hz to 20 kHz with under 3 % distortion, but the 85 dB sensitivity and 64 dB signal-to-noise ratio mean loud, bass-heavy content will not be its strength. It is not for users who need room-filling sound or deep low-frequency extension.
Tool-free mounting on compatible monitors
The soundbar slides onto the monitor via a lift mechanism and locks with the supplied key; no screws or tools are required. Installation normally fails only when the monitor is not a supported P or T Series model, when the USB port cannot deliver 1.6 A, or when the lock key is misplaced. It is not for owners of monitors outside the supported series or for setups that lack a suitable high-current USB port.

Questions about this item
Should I pick the MS30 or a different ThinkVision soundbar?
The MS30 is a single 2×2 W RMS model with USB-A power and a lift mount for P/T-30 monitors; other ThinkVision bars have different power or mounting so match your monitor series.
What does 2×2 W RMS mean at my desk?
Two front-facing drivers rated at 2 W each deliver 4 W total continuous output, measured at <3 % distortion and 85 dB sensitivity from 140 Hz to 20 kHz.
Does the USB-A connection limit volume or quality?
USB 2.0 supplies 5 V/1.6 A, capping the amplifier at its rated 4 W RMS; the 64 dB signal-to-noise ratio and 4 Ω impedance are unchanged by the interface.
