A faint sound behind a wall in your home is hard to make out by ear. This wall listening device carries it to you: press its high-sensitivity base to the wall and listen through the included stereo earphones. Turn the knob until the sound comes through clearly.

• Walls, doors and windows: The base picks up sound through wood and other walls, doors, windows and panels.
• High-sensitivity detector: Voices on the other side come through in full detail.
• One tuning knob: The same knob switches the device on and adjusts the sound until it is clear.
• Recorder-ready jack: Plug a voice recorder into the headphone jack for long recordings.
• Rechargeable: The charging jack sits on top, beside the headphone jack and knob.

What you need: A full charge before first use, and a voice recorder if you want to record.

In the box: Wall listening device, stereo earphones and charging cable. Voice recorder not included.

Good to know: The base must rest against the surface to pick up sound.
