Red I’m curious how easily these would fold into my bag when I switch from a listening session at home to a day out.
Nea I’d like to listen for the transition from piano to orchestra in “Day One,” then compare that build with a soundtrack I know well.
What Hi-Fi? hears tighter bass without losing its weight
What Hi-Fi? praises the XM4C’s musicality, balance, detail and dynamics. Its comparison with the original XM4 describes cleaner bass edges without sacrificing low-end weight or musical cohesion. The reviewers find the default tuning well balanced, even though Sony’s Sound Connect app offers a 10-band equalizer for adjustments.
With “Day One” from the Interstellar soundtrack, What Hi-Fi? singles out the delicate piano opening and the way the headphones follow the orchestral build, bringing out detail as the music swells.
For active noise cancelling (ANC), What Hi-Fi? reports good suppression of café chatter and bus-engine rumble, though it says more expensive models offer more refined performance.

Folding for travel, with a 27-hour battery rating
What Hi-Fi? found the WH-1000XM4C comfortable during both short and long listening sessions. The review highlights its folding design and included carry case as a portability advantage over the WH-1000XM5’s store-flat design.
The review lists rated battery life at 27 hours with ANC on, compared with 30 hours for the original WH-1000XM4. The headphones also have no IP rating for dust or water resistance, worth keeping in mind for outdoor use.
If folding portability appeals to you, try the fit where possible and compare locally offered prices for the WH-1000XM4C and WH-1000XM5 before choosing.
