Marshall Stanmore III Bluetooth Speaker, 80 W, Black

What to know before buying

Listing details to confirm

The listing's power details are contradictory: it calls the speaker battery powered and gives 20 Hours of battery life, but also lists a power cord in the package. It also describes Bluetooth and 3.5 mm input in feature text while the connection field lists Bluetooth and RCA. Confirm the actual power arrangement and available wired inputs for the selected listing before purchase. The stated 42 Centimeters speaker size also matches the 42H centimetres height in its dimensions, so treat that separate size field cautiously.

Who is it for?

A good fit for

Home listeners wanting a tabletop Bluetooth speaker with the option of a wired connection.
Buyers who value physical on-unit music controls and a speaker presented as a home audio model.

Less suited to

Anyone needing water-resistant audio equipment.
Buyers seeking a clearly confirmed battery-powered portable speaker, until the listing's power details are clarified.
