Model: Jr310 (wired)
This is an exact-model identification lookup for Blue item JBLJR310BLUAM and Red item JBLJR310REDAM, not a positive ANC recommendation. ANC and power-off behavior remain unknown rather than false, and no exact listing or stock state is asserted.
This model lookup is separate from the questionnaire shortlist. It does not certify that this model meets your selected requirements.
Reference lookup for the Blue and Red U.S. JBL Jr310 wired on-ear model. JBL documents a 3.5 mm connection and inline microphone/remote, but the inspected exact-model sources do not resolve ANC or powered-off playback.

Documented model details
- The separate U.S. selected items are Jr310 Blue JBLJR310BLUAM and Jr310 Red JBLJR310REDAM; the observed pages list the same wired Jr310 model specifications.
- JBL documents a 3.5 mm audio jack, a flat cable with combined inline microphone/remote, foldable on-ear design, 32 mm driver, one microphone and 105 g listed weight.
- The English sheet lists 32 ohm impedance, 80 dB SPL sensitivity at 1 kHz/1 mW and 20 Hz–20 kHz frequency response. These are manufacturer specifications, not independent acoustic measurements.
- JBL promotes an 85 dB Safe Sound volume claim. It is not an ANC feature or an independent safety measurement.
Limits to weigh
- The exact-model pages and sheet do not directly confirm or deny ANC or establish an ANC runtime; unknown is not ANC=false.
- The same sources do not establish a battery requirement or audio while unpowered. A 3.5 mm cable is not proof of passive, battery-free operation.
- Feature copy says a reusable sticker set is included, while the explicit box list and sheet do not list it. Check the package if stickers matter.
- The Safe Sound wording is a manufacturer claim, not independent measurement or a guarantee of safety. No ownership, fit, sound, durability or safety test is claimed.
Check before ordering
- Check the exact Jr310 name, selected finish and U.S. item code; do not substitute Jr310BT, Junior 320 or Junior 320BT.
- Confirm the source device supports 3.5 mm audio. If an adapter is needed, check microphone compatibility as well as playback; no adapter is established as included.
- Verify the exact package if the sticker set is important and review the seller's return terms before relying on marketing fit descriptions.
- If active noise cancellation is essential, choose an exact model with directly documented ANC rather than treating this reference as a match.
