AKG signature sound
- Light weight and soft leather pads
- Thanks to the K490 NCs’ soft leather ear pads, you’ll barely know that you’re wearing headphones. This feature, coupled with the headphones’ extremely light weight, is ideal for extended listening experiences.
- AKG signature sound
- For more than 65 years, musicians and audio engineers have relied on AKG technology within the studio for vocal performances, instrumentation, mixing, mastering and engineering. In the K490 NCs, this sought-after sound is now available for you to experience and enjoy.
- Continuous sound
- Even when the K490 NCs’ built-in battery has run dry, the supplied bypass cable lets you continue to listen to your audio. You can’t do that with most other noise-cancelling headphones.
