Before you buy
- Wired only: there is no Bluetooth, so it needs a source with a headphone output.
Who it suits
Made for how you listen
- Travel, where outside noise needs to stay out
- Commuting and everyday listening
Listening experience
In-ear monitors seal in the ear canal, which blocks outside sound without any electronics.
A dynamic driver moves a cone or dome from a voice coil, the most common headphone design.
Sennheiser lists a frequency response of 5 Hz – 48,000 Hz.
