Dyson OnTrac is an over-ear Bluetooth ANC headphone built around long rated battery life, a substantial 451 g chassis, physical customization, joystick controls, and the MyDyson app. This is a specification-based buying guide, not a hands-on sound or comfort test.
Quick answer: OnTrac stands out for up-to-55-hour battery life, eight ANC microphones, replaceable outer caps and cushions, and a 6 Hz–21 kHz manufacturer-stated response range. Its 451 g weight and Bluetooth-first workflow are important tradeoffs to evaluate in person.
The Core OnTrac Specifications
Dyson lists Bluetooth 5.0, a range of up to 9 m, USB-C charging, eight noise-cancelling microphones, one telephony microphone, and 40 mm neodymium drivers. The official OnTrac specification page is the best place to confirm the current hardware details.
| Decision area | What to verify | Why it matters |
|---|---|---|
| Battery and charging | Up to 55 hours; USB-C; quick-charge options documented by Dyson | Useful for long travel or workdays, but compare battery claims under similar feature settings. |
| Fit and mass | 451 g; microfiber cushions; battery distributed through the headband | The design aims to distribute weight, but comfort remains individual and should be tested. |
| ANC and controls | Eight ANC microphones, isolation/transparency modes, joystick plus touch gesture, MyDyson app | Controls are more physical than touch-only systems, while ANC modes depend on Dyson's processing. |
ANC and Transparency Are the Main Listening Modes
Dyson documents Isolation, Transparency, and ANC-off behavior. Double-tapping the outer cap switches between the main noise-control modes, while the app provides additional settings. The manufacturer claims up to 40 dB of total attenuation under its stated conditions; that figure should not be converted into a guarantee for every environment.
The 451 g Weight Is a Real Design Tradeoff
OnTrac is not a minimal lightweight headphone. Dyson uses soft microfiber cushions, gimbal movement, and headband battery placement to distribute the load. That engineering may help, but the only reliable comfort test is wearing the headphones for the length of session you expect.
Customization Is More Than a Color Choice
Users can swap outer caps and ear cushions. That makes OnTrac visually distinctive and can help replace visible wear parts, but the accessories add cost and do not change the underlying Bluetooth, ANC, or acoustic platform.
Separate the Product Review From the Price Question

How heavy is Dyson OnTrac?
Dyson lists a weight of 0.451 kg, about 0.99 lb. Comfort depends on fit and duration, so the weight should be tested rather than judged from the number alone.
Can I customize Dyson OnTrac?
Yes. Dyson sells interchangeable outer caps and ear cushions. Those parts change appearance and replaceable contact surfaces, not the core audio electronics.
