Bass
Bass-focused over-ear ANC headphones with Sony ULT modes for buyers wanting long battery life and multipoint below the flagship tier.
Trade-off: The ULT tuning is intentionally bass-forward, which is a preference rather than a universal advantage. Compare tuning, comfort and ANC needs instead of battery life alone.

BatteryTravel
Established premium Sennheiser over-ear headphones for buyers prioritising unusually long ANC battery life and broad aptX codec support.
Trade-off: MOMENTUM 5 is now the newer generation. MOMENTUM 4 can still be a valid current product, but compare generation-specific battery, codec, repairability and pricing rather than treating the names as interchangeable.

Deeper Australian Product Guide evidence - still verify the current retailer offer and exact variant before purchase.These products already overlap on anc, value; the deciding difference is more likely to be their distinctive use-case signals, exact specifications, current price and retailer availability.
Australian Product Guide does not currently have comparable maintained reference prices for every option in this shortlist, so price should be verified at the retailer rather than inferred.
None of the maintained options satisfies your non-negotiable deal-breakers, exact Australian model identity is unclear, or the evidence is too shallow for the decision you are making.
Exact model/variant, current retailer availability, current price, warranty/support terms and any specification that materially affects your use case.
