JBL Junior 320 Wired On-Ear Headphones (Blue and Purple U.S. finishes)
Model: Junior 320 (wired)
This is an exact-model identification lookup for Blue item JBLJR320BLUAM and Purple item JBLJR320PURAM, not a positive ANC recommendation. ANC and power-off behavior remain unknown rather than false, and no exact seller, offer 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 Purple U.S. JBL Junior 320 wired on-ear model. JBL documents a 3.5 mm connection, built-in microphone and fold-flat design, but the inspected exact-model sources do not resolve ANC or powered-off playback.

Documented model details
- The Blue and Purple U.S. selected items are JBLJR320BLUAM and JBLJR320PURAM. The current pages identify both as wired Junior 320 products with the same listed model specifications.
- JBL documents a wired Auxiliary connection and a 3.5 mm audio jack, with built-in microphone, hands-free calling and fold-flat design.
- The English sheet lists a 32 mm driver, 116.8 g, 34 ohm impedance, 78 dB sensitivity at 1 kHz and 20 Hz–20 kHz frequency response. These are manufacturer specifications, not independent acoustic tests.
- JBL's page and English sheet list a sticker set; the maker describes a volume-ceiling claim under its Safe Sound name. Neither detail establishes ANC.
Limits to weigh
- Exact-model pages and the sheet do not directly confirm or deny ANC, identify ANC runtime or state passive-only operation. Unknown is not ANC=false.
- The sources do not establish battery requirement or audio while unpowered. A 3.5 mm jack alone does not prove battery-free operation.
- The wired Junior 320 is distinct from Junior 320BT, Jr310 and Jr310BT; none of those models' Bluetooth, package or ANC claims are transferred here.
- The Safe Sound wording is a manufacturer claim, not an independent measurement or safety guarantee. No ownership, fit, sound, durability or safety test is claimed.
Check before ordering
- Check the complete Junior 320 name and exact Blue or Purple U.S. item number; do not substitute the wireless Junior 320BT or the distinct Jr310 family.
- Confirm that the source device supports 3.5 mm audio. If an adapter is required, check microphone compatibility as well as playback; no adapter is established as included.
- Verify the seller's package and return terms rather than generalizing a manufacturer's reference package to all offers.
- If active noise cancellation is essential, use a model with directly documented exact-version ANC instead of treating this reference as a match.
