Just bought the EarFun K2 in pink? These wireless kids headphones combine Bluetooth 5.4, dual safe volume limits and up to 40 hours of playtime. A clean first setup — pairing, volume mode and fit — is what keeps them on your child’s head instead of in a drawer. Here is how to set them up in five steps.

What you need
- EarFun K2 kids headphones (Pink)
- A smartphone, tablet or laptop with Bluetooth
- The USB-C charging cable from the box
- Two minutes with your child to check the fit
Step 1: Pair over Bluetooth 5.4
Hold the power button until you hear the pairing prompt, then select EarFun K2 in the Bluetooth list on the phone or tablet. Bluetooth 5.4 keeps the link stable for music, lessons and calls without a cable.
Step 2: Pick a safe volume
The K2 limits volume to 85 dB for study and everyday use, or 94 dB for travel and noisy places. Set the quieter limit before you hand the headphones over — it matches WHO-style guidance for protecting young ears.
Step 3: Adjust the soft fit
The memory foam headband and earpads are designed for kids. Extend both sides evenly until the cushions sit fully over the ears, not on top of them. A snug, even fit sounds clearer at lower volume and stays comfortable longer.
Step 4: Use the built-in mic
The K2 has a built-in microphone for hands-free calls and online lessons. Once paired, your child can answer short calls or join a class without swapping to another headset.
Step 5: Charge with USB-C
A full USB-C charge of about 2.5 hours delivers up to 40 hours of playtime, according to EarFun. Top up overnight before a school week or a long trip so the battery is not the reason they go unused.
Pro tip
Agree a simple house rule: 85 dB at home and at school, 94 dB only in the car, train or plane. Kids follow a rule they understand better than a setting they never see.
Keep them in good shape: fold the K2 after use, wipe the ear cushions with a dry or slightly damp cloth, and store the USB-C cable loosely coiled rather than wrapped tightly around the headband.
