The Sennheiser PXC 480 is a wired over-ear travel headset designed for long journeys and everyday listening. It uses a closed circumaural construction with a detachable 1.4 m audio cable and a built-in inline microphone for calls. This model is wired only: it has no Bluetooth connection, so audio is delivered through the 3.5 mm cable rather than a wireless link.Sennheiser equips the PXC 480 with NoiseGard hybrid active noise cancellation to reduce steady background noise while travelling. TalkThrough can be used with ANC switched on when you need to hear and speak with people nearby without removing the headphones. The headset also works passively when the battery is depleted, allowing normal wired listening without active noise cancellation.The headphone section covers a 17 Hz to 23 kHz frequency range, with a rated impedance of 18 ohms, sound pressure level of 109 dB at 1 kHz/1 Vrms and total harmonic distortion below 0.5% at 1 kHz/100 dB. A smart inline remote and microphone support phone calls and basic playback control from compatible source devices.The rechargeable battery powers the active noise-cancellation system for up to 50 hours and takes about three hours for a full charge. Charging is carried out by USB, while the main audio connection remains the detachable 3.5 mm cable. The foldable earcups and padded headband are intended for travel and compact storage between journeys.The PXC 480 weighs approximately 225 g and is supplied in black. Sennheiser article number 506518 identifies this model. Documented accessories include the detachable audio cable, USB charging cable, in-flight entertainment adapter and travel case.
