The OHR668’s foldable hinge and padded headband are the two things that actually matter once a kid is using these daily — not the spec sheet.
$24.69 buys you a pair of kids’ headphones that caps volume at 85/94dB, folds flat, and claims 60 hours of playtime. After going through the spec sheet and cross-checking it against what verified buyers are reporting after weeks of real use, the battery claim holds up. That’s the part most cheap kids’ headphones fail on.
Is the acer OHR668 Actually Safe for Kids’ Hearing?
Yes. The OHR668 hard-caps output at 85dB or 94dB depending on the mode selected, which sits inside the range pediatric audiologists generally consider safe for extended listening, and the headphones are CPSIA-certified and BPA-free.
That distinction matters more than it sounds. A lot of “kids” headphones on Amazon just slap a smaller headband on adult drivers and call it a day — the actual volume is still whatever the tablet or phone is set to. This one limits output at the headphone hardware level, so a kid maxing out the volume slider on an iPad still can’t blow past the cap.


Purple Green and Blue Red are two of six available colorways — most buyers picked based on which kid would actually stop complaining about the color.
How Long Does the Battery Actually Last?
acer rates the OHR668 at 60 hours of Bluetooth playtime, and multiple verified buyers report only charging once every several days to a couple weeks during daily use — which lines up with the rating better than most kids’ electronics do.
One parent of a nine-year-old reported daily multi-hour use for over a month with just one recharge in the past few days. A second buyer said their child’s headphones go several days between charges even without tracking exact hours. For a $25 product, that’s an unusually accurate battery claim. The USB-C quick-charge spec (2 hours of playtime from a 5-minute charge) also means a dead battery before a road trip isn’t a real problem.
Will They Hold Up to Daily Kid Use?
The reinforced folding hinge and ABS plastic shell are built specifically for school bags and backpacks, and reviewers with grandkids who previously destroyed corded headphones report the OHR668 holding up well after weeks of regular handling.
One buyer specifically switched from corded headphones because their grandson kept bending the plug — the wireless design sidesteps that entire failure point. Memory foam ear cushions and an adjustable headband also mean these aren’t a one-size-fits-most guess; multiple reviewers across different age kids (2 to 11 years old) said the fit worked.
The Reality of Long-Term Ownership
Hidden Costs: None beyond a USB-C cable, which is included. No subscription, no proprietary charging dock to lose.
The Tinkerer’s Hack: If the wired 3.5mm mode ever outputs to only one ear, don’t assume the headphones are defective — test the cable and source jack first. One reviewer hit exactly this issue and it traced back to the device, not the headphones.
Pros and Cons
Pros
- Hardware volume limiter, not just a software cap
- Battery life matches the 60-hour claim in real-world reports
- Foldable, durable hinge survives backpacks
- Fits a wide age range, 2 to 11+ per buyer reports
- Quick 5-minute charge buys 2 hours of playtime
Cons
- Wired 3.5mm mode can output to one ear if the cable or source jack has issues

- Touch controls take a few tries for younger kids to learn
Frequently Asked Questions
What age range are the acer OHR668 headphones designed for?
acer markets them broadly for kids, and reviewer reports span ages 2 through 11+. Buyers with toddlers note the fit runs a little large, while the adjustable headband accommodates growth through the pre-teen years.
Do the headphones work with devices other than tablets?
Yes. Bluetooth 6.0 pairs with any standard smartphone, tablet, or laptop, and the included 3.5mm cable adds a wired fallback for devices without Bluetooth or for in-flight entertainment systems.
Can a child override the volume limiter?
No. The 85/94dB cap is enforced at the headphone hardware level, so turning up the source device’s volume doesn’t bypass it.
How long does a full charge actually last with daily use?
Buyers running these for hours daily report going multiple days to over a week between charges, consistent with the 60-hour rating.
Is the microphone good enough for online classes?
acer includes a built-in mic rated for calls and interactive learning use; no buyer reports in the reviewed feedback flagged mic quality as a problem.

What Pairs Well With These Headphones?
A Bluetooth headset is only half the setup for a kid’s tablet routine — the Amazon Fire 7 Kids tablet is the most commonly paired device, with parental controls and a kid-proof case built in.
