Why you'll like it

• Gravity sensor — rotate to any of 8 sides to select the corresponding sound
• 8 built-in sounds: ocean waves, piano, jungle birds, rain, stream, cicadas, fan, strong wind
• Timer: 15 / 30 / 60 / 90 minutes + continuous play
• Ambient noise masking — auto-detects room level and plays above it
• 500mAh, 15-day standby, Type-C, 71g — 49mm × 50mm cylindrical

Designed as a compact desktop white noise machine with physical gesture-based sound selection

The T11 uses a gravity sensor to assign one sound to each of its 8 sides — rotating the cylinder to a given side starts that side's corresponding sound. No button press or menu navigation is required to switch sounds. The 40mm full-range speaker delivers 2W output from the 49mm × 50mm cylindrical body. The ambient noise masking feature reads the room's background noise level and sets the playback volume above it automatically. Charging: Type-C at 5V. Standby: approx 15 days on a full charge.

Key features

Gravity sensor — 8 sides, 8 sounds

The T11 uses a gravity sensor to detect which side the cylinder is resting on. Each of the 8 sides corresponds to one of the 8 built-in sounds — place the device on the relevant side to start that sound. Rotating between sides changes the sound without any button interaction. This is a fixed assignment of one sound per side and is not user-configurable based on the source specification.

8 built-in sounds

The eight sounds are: ocean waves, piano, jungle birds, rain, stream, cicadas, fan, and strong wind. Each sound is assigned to one of the eight sides of the cylindrical body and is selected via the gravity sensor.

Timer: 15 / 30 / 60 / 90 minutes, plus continuous play

The timer can be set to 15, 30, 60, or 90 minutes, after which the unit switches off automatically. A continuous play mode is also available for uninterrupted playback without an auto-off timer.

Ambient noise masking — M button detection

A long press of the M button activates the ambient noise detection function. The T11 measures the current ambient noise level in the room and sets its playback volume to a level above the detected ambient noise. This adjusts playback automatically to the room conditions rather than requiring manual volume setting.

500mAh — 15-day standby — Type-C — 40mm speaker

The 500mAh polymer lithium battery provides approximately 15 days of standby. Active playback runtime on a full charge is not specified in the source. Charging: Type-C at 5V input. Speaker: 40mm, 4Ω, 2W, full-range internal magnet. Frequency response: 20Hz-20kHz. Material: metal silver exterior (scratch-resistant, laser-engraved). Dimensions: 49mm diameter × 50mm height. Weight: 71g. Blue LED display. No certifications listed in source.
