  1. Q2 202673/1004.6★5 reviews

    Buyers praised fit, comfort, volume control, and battery life for kids. One reported durability issue with ear cushion on a toddler.

    • Fits well and comfortable for children aged 5-9.
    • Volume control feature appreciated for hearing safety.
    • Good battery life and comes pre-charged.
    • Ear cushion not durable for toddlers, hard to reattach.
  2. Q1 202587/1004.6★8 reviews

    Kids love these headphones for their comfort, ease of use, and JBL sound. Parental volume control, long battery life, and flexibility for travel are praised, though some note the build feels fragile.

    • Comfortable fit for kids, with plush pads and correct clamp force.
    • Parental control app allows volume limiting and screen time management.
    • Sound quality is good but not exceptional; JBL bass is present but can be underwhelming.
    • Headphones feel a little cheap and fragile, raising durability concerns.
