Verdict

The JBL JR300BT is a lightweight (113g) on-ear wireless headphone specifically designed for children, featuring 32mm dynamic drivers and a frequency response of 20Hz–20kHz. Its primary characteristic is the JBL Safe Sound technology, which limits volume levels to 85dB to protect young ears. The device offers up to 12 hours of battery life with a quick-charge feature providing 1 hour of playback from just 10 minutes of charging, and it includes a Bluetooth range of up to 15 metres. Main pros include a highly portable foldable design, soft padded headband and ear cushions for a comfortable 'feathery' fit, and included stickers for personal customization. Some notable cons include a flimsy all-plastic construction that lacks long-term durability, poor passive noise isolation, and the absence of a 3.5mm wired audio jack for passive listening.
