Contixo KB 300 Kids Bluetooth Wireless Headphones | 85db Volume Limiting, Microphone, MicroSD Card Player, Wired 3.5mm AUX Cable, Music Streaming, Colorful LED Lights (Blue + Yellow)

The Contixo KB-300 is an over-ear wireless headphone for children, with an 85dB volume limit, Bluetooth 3.0, a microphone, and a 3.5mm wired option—suited to kids who need flexible listening across compatible devices.

Recommended For

• Children whose caregivers want a built-in 85 dB volume limit for everyday listening to music, videos, or games.
• Families packing headphones for tablet or phone use on trips, who want Bluetooth listening with a 3.5 mm wired option as an alternative.
• Children who need music without carrying a phone or tablet, since the headphones support MicroSD-card playback and FM radio.
• Kids who enjoy colorful, light-up headphones for casual listening; a Best Buy purchaser specifically noted that their child liked the lights.

Real-World Use Scenarios

• During tablet or phone listening at home, a child can use Bluetooth for music and videos without a headphone cable running to the device; the listed 85 dB volume limit is intended to cap listening volume.
• On a car trip, a child can listen to videos or music from a paired device without keeping it beside them; the headphones’ volume limit is a stated feature, not an independent measurement of the sound level in every setup.
• For a compatible laptop, tablet, or other device with a 3.5 mm headphone jack, a child can use the included wired connection instead of Bluetooth; this is useful when the source device does not support Bluetooth.
• For music away from a phone or tablet, a child can play supported audio files from a MicroSD card inserted in the headphones, without streaming from a paired device.
• When a child uses a paired phone, the built-in microphone and call-acceptance function can be used for calls without holding the phone at the headphones.
