Before you buy
- Open-back: sound escapes the earcups and room noise comes in, so it does not suit shared spaces, offices, or travel.
- Wired only: there is no Bluetooth, so it needs a source with a headphone output.
- Rated at 300 Ω. High-impedance headphones need more voltage than many phones and laptops provide, so a dedicated headphone amplifier is common.
Who it suits
Made for how you listen
- Listening at home in a quiet room
Listening experience
The open-back design lets sound pass through the grilles, so it is not sealed in around your ears and you stay aware of the room.
A dynamic driver moves a cone or dome from a voice coil, the most common headphone design.
Sennheiser lists a frequency response of 4 Hz – 51,000 Hz.
