Overview
Plugging into a standard headphone jack, these Acer kids headphones add a volume limiter, passive noise isolation and a tangle free cord for school and travel. The foldable ABS frame has an adjustable band and volume buttons.
A wired link, a mic and a hearing limiter suit classroom tablets, laptops and game systems, and the foldable frame travels well. The limitation is that the ear placement entries conflict between on ear and over ear.
Who it's for
Parents buying for children who study on tablets, laptops or consoles with a headphone jack are the target. Families with devices that only offer a USB C port, or who want wireless freedom, should pick another style.
Pros and cons
- Volume limiter for young ears
- Built in mic
- Foldable and adjustable
- Tangle free cable
- Ear placement entries conflict
- Adapter needed for jackless devices
Performance notes
A dynamic driver in each ear cup produces the sound, and the limiter caps the output level within the stated range. Passive isolation blocks some room noise by cup fit rather than electronics. A push button controls the volume at the cup.
