WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

Samsung Sound Tower ST40F

What it brings

Mains operation and a replaceable rechargeable battery provide two power options, with their different maximum output ratings kept explicit.
Manufacturer source Manufacturer source
Bluetooth, USB music, analogue inputs and two microphone jacks support several source and performance setups.
Manufacturer source Manufacturer source
Two matching units can form a wireless stereo pair, while wireless Group Play supports up to ten supported Sound Towers.
Manufacturer source

What to check

The 160 W headline is a maximum amplifier claim on mains. Battery output is listed as 80 W, and neither figure is an independent loudness measurement.
Manufacturer source Manufacturer source
The 12-hour battery claim was tested with lights off at volume 12–13; actual use can differ.
Manufacturer source Manufacturer source
Samsung’s documents disagree about the number of lighting modes and the app’s minimum Android/iOS versions, so those details remain unresolved.
Manufacturer source Manufacturer source

Logitech Z313

What it brings

A separate subwoofer rated down to 40 Hz handles bass that small satellites alone would not reach.
Manufacturer source Manufacturer source
Power, volume and a headphone jack are on the wired control pod.
Manufacturer source Manufacturer source

What to check

A single analogue 3.5 mm connection is the only input: there is no Bluetooth, USB or optical option.
Manufacturer source Manufacturer source
The 150 × 220 mm subwoofer footprint needs floor or desk space in addition to the two satellites.
