Each option is a separate wired configuration. The listing does not establish that one pair includes all three connectors. Although the original title said “Wireless,” the supplier specifications and selectable options describe wired headphones; wireless or Bluetooth operation is not promised.

The impedance entry appears as “32?” and the sensitivity entry as “-44�3dB.” Their original symbols, units and meaning require supplier confirmation rather than being silently corrected.

Noise reduction and compatibility

The supplier describes noise reduction but does not identify whether it is passive isolation, active noise cancellation or microphone noise reduction. Active noise cancellation and specific performance benefits are not confirmed. A microphone's presence and specifications also need confirmation.

Check connector type, device audio support and any adapter requirements before ordering. A matching connector alone does not guarantee full device compatibility.

• One pair of headphones.
• One velvet bag.
• One 1-to-2 adapter; confirm connector types and inclusion for the selected version.
