SONY Active Speaker SRS-T33 with 2m extension cord and battery for operation check

SONY Active Speaker SRS-T33 with 2m extension cord.
Operation has been confirmed. I was using it connected to the TV until last night, listening by my bedside.

The original cord that came with the unit is about 20cm long, which is quite short, so I'm including a 2m extension cord.
This makes it convenient to connect to TVs that are a bit further away.
Volume adjustment is done on the source device.
The speaker will produce sound even without batteries, though at a low volume. If you turn up the volume too high on the source device, the sound will distort. The sound quality is more towards the treble, with less bass.
There are no signs of battery leakage in the battery compartment.

There are a few small, inconspicuous scuffs on the main unit (please check the images).

What will be sent is the main unit, the 2m extension cable, and batteries for testing.

Measurements are approximate.
Width: Approx. 17cm
Height: Approx. 5cm
Depth: Approx. 3cm
Weight (with 2 AAA batteries): Approx. 170g

Thank you.
