HEADPHONES

Noise complaints welcome
Our engineers used a 40 mm titanium-coated diaphragm to deliver expressive highs and deep bass at up to 110 dB. The driver boosts low-end impact, while a next-gen magnet and voice-coil system increase sensitivity.
AI-boosted Dynamic Bass Enhancement locks on to low frequencies and boosts them in real time, adding power to make beats bigger without distortion.

Headphone (a) is Hi-Res Audio certified for wired and wireless listening.
Our engineers used LDAC wireless technology for high-quality 24-bit/96kHz audio without cords. And you can connect with a USB‑C or 3.5 mm jack.

Leave me alone
Stop responding to strangers on the train.
Using AI to power dual feedforward and feedback microphones, three levels of Active Noise Cancellation¹ block distractions. Transparency Mode lets the world in by picking up sounds from your surroundings in real time.

Huh?
Trained on over 28 million real-world scenarios, AI-powered Clear Voice Technology uses the three microphones on Headphone (a) to keep every call crisp and echo-free – in crowds, cafés and windy conditions.

Swap easier
Switching between phones and computers is easy with low latency, dual-device connections on Android, Windows and iOS.

Hot enough to make your ex jealous
Our designers crafted a transparent case to show off the locations of mechanical structures like the battery and flex cables.
New Pink and Yellow colourways join our classic Black and White line-up for a more expressive take on the playful (a) series.

5 days, no sleep
Our engineers fitted two core batteries for up to 5 days² of power – that's over 135 hours of playback. A dual-core chipset keeps AI-powered Active Noise Cancellation in full force for over 75 hours on a single charge.

Charge fast, anywhere
Get 8 hours of playback in 5 minutes. And go from zero to full in 2 hours.
On-the-go charging keeps Headphone (a) powered everywhere.
