Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Type — ANC Bluetooth headphones (battery)
Bose's standard over-ear ANC headphones (no Immersive Audio — that is the Ultra). Bluetooth, battery-powered; battery/ANC/Bluetooth symptoms apply.
ANC modes
Adjustable noise-cancellation and Aware modes via the buttons or the Bose app. ANC on continuously shortens runtime versus the headline figure.
Battery & charging
Long rated battery; charge by USB-C. Short runtime is usually ANC at high volume; a big long-term drop is battery ageing.
Power path
Internal or removable battery. Every capability that costs current — night vision, higher stream quality, longer recordings, frequent events — is paid for in runtime, so a change in behaviour after a settings change is usually a power consequence rather than a fault. Cold weather reduces usable capacity sharply.

Exact questions

Questions that only have an answer for the Bose QuietComfort Headphones

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

One side of my Bose QuietComfort Headphones is quieter or cuts out.+

First check the audio balance slider in your phone's accessibility settings — it affects everything and is easy to nudge off-centre. Then make sure both earcups are charged and the headphones are fully updated in the Bose app. If one side still cuts out on every source, it points to a hardware fault (an internal connection), which Bose service handles. Bluetooth dropouts affecting both sides are usually range or interference, not a one-side fault.

Structured depth, not empty permutations

Every published record carries a direct answer, scope, ordered fixes, risk notes and sources.

Device and manufacturer hubs share a consistent record system, but each answer carries the relevant controls, fault boundaries, consequences and official support entry point for that platform.
