BuddyPhones Cosmos+
$70 under your budget
The pick for an older kid who won't wear 'kiddy' cans — grown-up styling, a 94 dB step-up, ANC and a boom mic, vetted across 7 independent tests.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
Its battery is the shortest here — 24 hours. Against the JBL's 50 and the EarFun's 120, it's a nightly-charge headphone, and it's frequently out of stock on Amazon, so you buy direct from Onanoff. You're paying for style and the mic, not endurance.
Dealbreaker? Runner-up — EarFun K4NC gives 120h and ANC for less ↓

Traps — this verdict avoids
Why the BuddyPhones Cosmos+ is right for you
It avoids every trap below — and for family of 4, under $150, it is the pick because it delivers:
The label is a claim, not a measurement
One in three kids headphones exceed their own rated cap in independent lab tests. A box that says 85 dB is not proof — we weight picks by tested limiter accuracy, not marketing.
85 dB isn't a free pass
85 dB assumes limited daily exposure. For a child under 4, or any session past 2 hours, drop to a 75 dB mode — extended listening at 85 dB still risks hearing damage.
Wired mode can void the limiter
Plug the cable in wrong on some models and unlimited volume pipes straight through — a limiter that only works over Bluetooth protects nothing on a school Chromebook. Confirm it caps in both modes.
