What Buyers Say
EarFun K1
Overall, these kids' headphones receive mostly positive feedback for their comfort, sound quality, and child-friendly features like volume limiting. However, a few verified reviews report early breakage within months, which lowers the overall score. The product seems well-suited for school use and younger children, though some older kids may find them tight after extended wear.
Pros
- Comfortable for children
- Good sound quality
- Volume limiting for ear protection
- Braided cord for durability
- Lightweight design
Cons
- Breaks within months
- Tight for older children
- Not extremely robust
- Slightly loud for sensitive ears
Sony ULT WEAR WHULT900N/B
The Sony ULT WEAR headphones deliver impressive noise cancellation and powerful bass via the ULT button, with many users praising the long battery life and comfortable fit. Sound quality improves significantly after using the companion app to customize the EQ, though some find the default sound muddy and the ULT bass boost overwhelming. A few long-term users report scratchy audio after two years, and the headphones are noted as bulky for some.

Cons
- Default sound is muddy without EQ
