Which is more comfortable?
Comfort is personal, but the A30 and ONE-X are both designed for extended wear. Bose emphasizes reduced clamping force and ergonomic earcup geometry, while the ONE-X uses plush leatherette ear seals, a vented head pad and an adjustable alloy suspension.
Our pick for premium around-ear comfort: Bose A30. The ONE-X remains an excellent alternative, especially if its fit and headband feel better on your head.
Which has better noise reduction?
The two systems use different approaches. Bose uses active noise reduction with selectable modes, while David Clark’s ONE-X uses hybrid electronic noise cancellation with external and internal microphones working together to generate an anti-noise signal.
Do not choose solely from a single attenuation number. Headset fit, ear-seal condition and the actual noise profile of your aircraft all affect the result.
Best for adjustability: Bose A30. Strong alternative: David Clark ONE-X.
Which has better battery life?
On the published figures, the ONE-X has the advantage: up to 50 hours from two AA batteries compared with up to 45 hours for the A30. Actual runtime varies with usage, Bluetooth and operating conditions.
Bose A30 vs David Clark PRO-X2
The Bose A30 vs David Clark PRO-X2 comparison is different because the two headsets use different ear-coupling designs. The A30 is around-ear; the PRO-X2 is supra-aural.
| Feature | Bose A30 | David Clark PRO-X2 |
|---|---|---|
| Design | Around-ear | Supra-aural |
| Weight | Approx. 12 oz | About 7.5 oz without cable |
| Noise reduction | Active noise reduction | Hybrid electronic noise cancellation |
| Bluetooth | Yes | Available on applicable configurations |
| Battery | 2 × AA; up to 45 hours published | 2 × AA; up to 50 hours published |
| Microphone | Noise-cancelling electret | Noise-cancelling electret |
| Warranty | 5 years | 5 years |
| Best advantage | Comfort and versatility | Low weight |
When should you choose the PRO-X2?
The PRO-X2 deserves serious consideration if headset weight is a major priority. Its supra-aural design and low published headset weight make it attractive to pilots who do not want a large circumaural headset.
If you prefer the feeling of your ears being fully enclosed, however, the A30 is the more natural choice.
Comfort, weight and long flights
If you regularly fly two, three or four hours at a time, comfort should be treated as a primary buying criterion rather than a cosmetic feature.
For long GA and IFR flights: start with the A30 and ONE-X if you prefer an around-ear headset. Consider the PRO-X2 if minimizing weight is your overriding concern.
Noise reduction: which headset is right for your cockpit?
There is no universal winner based on a single noise-reduction number. The best headset is the one whose acoustic design matches the aircraft you actually fly.
Favor around-ear designs
The A30 and ONE-X provide full around-ear coverage. Proper ear-seal fit is especially important in a high-noise cockpit.
Favor flexibility
The A30’s selectable noise-reduction modes and connector options make it a strong all-round choice.
Consider PRO-X2
If the lightest possible headset matters more than a circumaural design, the PRO-X2 deserves a closer look.
Noise reduction is also affected by ear-seal condition, glasses, fit, microphone placement and aircraft noise. Replace worn seals and windscreens when necessary rather than judging a headset with degraded accessories.
Bluetooth and connector options
Connector compatibility is one of the easiest details to overlook when buying an aviation headset. A premium headset is still the wrong purchase if it does not match your aircraft’s audio system.

- Dual GA configurations are available for common general-aviation applications.
- U174 configurations are available for helicopter applications.
- 6-pin configurations are available for applicable panel-powered aircraft.

For helicopter pilots
Connector selection is critical. The Bose A30 is available in a U174 helicopter configuration. Confirm the exact audio-panel connection required by your aircraft before ordering.
For pilots who fly multiple aircraft
The A30 is particularly attractive when connector flexibility is important. If you fly several aircraft, compare the available cable configuration with the headset jack in each aircraft before purchasing.
