Momentum 5 vs Sony XM6: What Happens When the Battery Wears Out?

Sennheiser Momentum 5 or Sony WH-1000XM6: which pair makes more sense beyond the first week? We compare documented battery replacement routes, manufacturer runtime claims, passive wired listening, pad access, phone compatibility, folding, and the costs worth checking before you buy. A replaceable battery can help, but parts availability matters. A longer runtime rating is not a lifespan guarantee. Here is how to make the comparison practical.

This is an ownership comparison based on published documentation, not an original hands-on ANC or sound test. The 57-hour and 30-hour figures are manufacturer ANC-on maxima under different test conditions. Sony lists lower runtime for some codecs. Sennheiser's BA500 replacement-part availability varies by region; check local supply and service quotes. No repair price, failure rate, or lifespan is predicted. Repair images illustrate construction, not a repair tutorial; use the complete model-specific instructions for any work. Source footage: Sennheiser, Sony, WhatGear; teardown photographs: iFixit.
