Turn theworlddown.
Sonder H2 are over-ear wireless headphones with noise cancelling. One button on the right cup moves between a quiet room and the room you are actually in.
Two modes
Microphones on the outside of each cup hear the room. What the driver does with that sound depends on the mode you pick.
Noise cancelling
The driver plays the same sound turned upside down. The two waves meet at your ear and cancel out.
Outside noise, through the cushion
Inverted wave from the driver
What reaches your ear
Transparency
The driver plays the room back in step with it, so voices and traffic sound as they would without headphones.
Outside sound, through the cushion
The same sound, played back by the driver
What reaches your ear
Inside the ear cup
A cut through the left cup, from the outside shell to the side that rests on your head.
- A
- Shell
- Glass-filled nylon, closed at the back so the sound stays in the cup.
- B
- Microphone ports
- Two small openings on the outside of each cup lead to the microphones that listen to the room.
- C
- Battery and board
- The cell sits at the back of the cup, behind the circuit board and away from the driver.
- D
- Driver
- A 40 mm dynamic driver with a thin film diaphragm, mounted on a baffle with a fine mesh in front.
- E
- Foam
- Slow memory foam that takes the shape of your head and seals out much of the room on its own.
- F
- Cushion cover
- Soft synthetic leather, stitched around the edge and replaceable when it wears.
What it does
- Each cup has two microphones outside and one inside, so the headphones can check how well the cancelling is working and correct it.
- Press the button on the right cup once to switch between noise cancelling and transparency; hold it to turn both off.
- The cushions are deep enough that your ears do not touch the driver, even after a few hours.
- The cups turn flat and fold into the headband, so the headphones fit in a bag without a case.
- Ten minutes on USB-C gives about three hours of listening, and a 3.5 mm socket takes a cable when the battery is empty.
