Somni, a UK-based company, has introduced a wireless earbud that doesn’t need to be charged. The exceptionally small earbuds were specifically designed for sleep. So, how do these interesting earbuds work?

UK-based Somni has developed a unique wireless earbud to provide a better sleep experience. The company describes their earbuds, called SomniBuds, as the world’s smallest sleep headphones that don’t require charging.

How Do SomniBuds Work?

The SomniBuds operate through a thin and soft mat (SomniMat). This mat can be placed under a pillow, on the bed, or behind a headboard, up to a distance of approximately 60-90 cm. The mat connects to a device like a phone or tablet via Bluetooth and transmits sound to the earbuds using a magnetic field.

The earbuds contain no batteries or electronic circuits. According to the company, the earbuds house an extremely sensitive magnetic diaphragm enclosed in an acoustic chamber. This diaphragm is mechanically moved by the SomniMat’s voice coil field, similar to how a speaker cone is moved within a speaker. This system is based on a proprietary, patent-pending technology developed by the company.

Because they have no batteries, the earbuds are exceptionally small, with a flat design that is only 3 mm thick. This ensures they don’t protrude from the ear, making them comfortable to wear while lying on your side. The ear tips are made of foam that provides a snug fit and passively blocks out external noise. The company states that this design can reduce outside noise by up to 37 dB, helping to mask disruptive sounds even at low volume levels.

In addition to the earbuds, the system includes two other components: the aforementioned cloth-like mat and a power adapter that also contains the Bluetooth receiver.

Somni notes that while their earbuds provide high-quality sound within the mat’s range, they deliver mono sound instead of stereo. Therefore, the product is not intended for listening to music or for use outdoors; it is designed specifically for sleep. A single earbud set is priced at $300, but is currently available for $231 as part of a Kickstarter campaign. The DuoMat package, designed for two people to use simultaneously, is being sold for $251 during the campaign. The company says deliveries are expected to begin in December.
