Quick Take
Overall Score: 8.4/10
Onanoff BuddyPhones Cosmos+ takes a unique approach with three switchable volume settings: 75dB for toddlers, 85dB for kids, and 94dB for travel mode where ambient noise is louder. Combined with ANC, this flexibility covers more use cases than fixed-limit headphones.
The Verdict: Best mid-range ANC kids headphones. The flexible volume limits are useful, though Puro PuroQuiet has better audio quality and stricter protection.
Safety Analysis
Switchable Volume Limits
- ToddlerMode (75dB): Strictest limit for youngest users
- KidsMode (85dB): WHO-recommended level for typical use
- TravelMode (94dB): Higher limit to overcome airplane/transit noise
Parents can lock the mode selection to prevent kids from overriding.
Active Noise Cancellation
ANC reduces ambient noise, allowing lower listening volumes. Less aggressive than Puro but effective for typical noisy environments.
