JBL JR300BT Wireless On-Ear Headphones for Kids (Rocker Blue)
Model: JR300BT
This is an identification lookup for Rocker Blue item JBLJR300BTUNOAM, not a positive ANC recommendation. JBL's U.S. page labels one runtime field 'with ANC off' while listing 12-hour maximum playtime; the exact-model guides do not resolve this wording or establish an ANC mode.
This model lookup is separate from the questionnaire shortlist. It does not certify that this model meets your selected requirements.
Reference lookup for the exact Rocker Blue U.S. JBL JR300BT item. Its Bluetooth 4.0 identity and generic runtime sources are documented, but ANC remains unresolved.

Documented model details
- The U.S. page identifies Rocker Blue item JBLJR300BTUNOAM, a wireless on-ear JR300BT with Bluetooth 4.0, 32 mm driver, built-in microphone, ear-cup controls and foldable construction.
- The exact U.S. page and model-specific quick-start guide list 110 g; a global English specification sheet lists 113 g, which is not transferred to the U.S. item.
- The exact-model QSG lists a 170 mAh, 3.7 V battery and generic 12-hour music playback. The U.S. page separately shows a 10-hour 'with ANC off' field and 12-hour maximum playtime.
Limits to weigh
- The 10-hour label is preserved but does not by itself confirm that active ANC exists; no ANC-on or independently verified ANC-off runtime is asserted.
- The runtime fields are not reconciled by the inspected source material, and ANC remains unknown rather than false.
- The global sheet's 113 g figure differs from the U.S. page and exact-model QSG; it is kept separate from this U.S. item.
- No analog audio input, powered-off playback behavior, current availability, price, seller status, or hands-on test is established here.
Check before ordering
- Check the complete JR300BT name, Rocker Blue finish and U.S. item JBLJR300BTUNOAM; do not confuse it with wired JR300 or later Jr310BT.
- Confirm the seller's package, condition and return terms, especially if you require an audio cable or another operating path beyond Bluetooth.
- Ask for a model-specific explanation of the 10-hour and 12-hour runtime fields if a mode-specific runtime is important; do not treat either as a verified ANC rating.
- If documented ANC is a hard requirement, use an exact-model source that directly establishes the mode instead of relying on the table label.
