Why consider this model?

  • An earlier-model reference for a shopper comparing the exact U.S. Article No. 508337 who needs around-ear ANC, two active Bluetooth connections, or a documented powered 2.5 mm cable route.

Tradeoffs to weigh

  • Sennheiser marks the PXC 550-II end of life. Its 20-hour Bluetooth-plus-ANC and 30-hour only-ANC figures describe different modes; the analog route requires a charged headset for ANC, and neither rating establishes an older unit's current battery condition.
