Direct answer
For the Bose Smart Soundbar 600, pairings, app account, EQ, groups and stored settings may be removed. First, confirm exact model and record current connections/settings.
What this covers
- Bose Smart Soundbar 600 (873973)
- Bose product; Bluetooth multipoint, app generation, wired input and spatial/ANC features vary.
- The specific fault this record addresses: needs a safe reset or will not reset
What it does not cover
- ×The same symptom on a different Bose product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
A power cycle is sufficient
What separates it General unresponsiveness with no specific fault.
How to confirm Powering off and on, or returning earbuds to the case and closing it, resolves a large share of transient problems with no loss of settings.
- 2
The pairing needs clearing rather than the device resetting
What separates it Connection problems specific to one source device.
How to confirm Forgetting the device on that source and pairing again is far less disruptive than a factory reset and fixes most connection problems.
- 3
The reset sequence being used is for a different model
What separates it Repeated attempts do nothing.
How to confirm Reset sequences differ between models and even generations. Use the manual for this exact model rather than a sequence found for a similar one.
- 4
A factory reset is genuinely needed
What separates it Persistent problems that survive power cycling and re-pairing.
How to confirm Expect to lose every pairing and setting, and to re-pair with every device afterwards.
- 5
The device is being sold or given away
What separates it A reset wanted to remove personal data rather than fix a fault.
How to confirm Also remove the device from the account in the companion app, since a factory reset alone does not always release cloud ownership.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether the problem affects one source device or all of them — one source needs re-pairing, not a reset.
- Whether a power cycle has been tried.
- The exact model, since reset sequences differ between generations.
- What will be lost: pairings, EQ settings, room calibration, group configuration.
Power cycle first
ReversibleOff and on, or both earbuds back in the case with the lid closed, resolves many transient problems and loses nothing.
Forget the device on the source and pair again
ReversibleThis fixes most connection problems and is far less disruptive than a factory reset.
Use the exact reset sequence from this model's manual
ReversibleSequences differ between models and generations, and the wrong one simply does nothing.
Note what a factory reset will erase before running one
Reset / data riskPairings, EQ, room calibration and group configuration all go, and everything must be re-paired afterwards.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- 873973. Bose product; Bluetooth multipoint, app generation, wired input and spatial/ANC features vary.
- Type — compact Atmos soundbar (WiFi + eARC)
- A compact Dolby Atmos soundbar with up-firing drivers, connecting by HDMI eARC and WiFi. 'No TV sound' is the eARC/HDMI-CEC link; streaming/app is WiFi. Smaller than the Smart Ultra but with real Atmos height drivers.
- Voice & app
- Built-in voice assistants and Bose Music app setup; pairs with Bose surrounds and the Bass Module wirelessly for fuller sound.
- eARC + CEC
- Use the eARC/ARC port and enable HDMI-CEC; power-cycle both to fix a lost handshake.
- Symptom boundary
- This record covers Bose Smart Soundbar 600 when it needs a safe reset or will not reset. A different symptom on the same hardware, or this symptom on a different Bose product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Remove the device from your account in the companion app before selling or giving it away — a factory reset alone does not always release cloud ownership, and the next owner may be unable to claim it.

Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Bose Support publishes this as "Product support". Official Bose product support; this key exists so smart-soundbar-600 cites its OWN articles — Bose publishes one per symptom per product. What that article does not carry is the model boundary — it is written for a product line, and 873973 is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
Should I add a subwoofer to my Bose Smart Soundbar 600?+
The 600 is a compact Atmos bar, so its deep bass is limited by size — if you want more low end, it pairs wirelessly with the Bose Bass Module (such as the Bass Module 700), which is the intended way to add bass. That is a design characteristic, not a fault. For dialogue clarity without a sub, the soundbar's dialogue mode helps. Add Bose surrounds and a bass module through the Bose Music app for a fuller system.
Should I factory reset to fix a connection problem?+
Almost never as a first step. Try a power cycle, then forget the device on that particular source and pair it again — that fixes most connection problems and costs you nothing. A factory reset erases every pairing, your EQ settings and any room calibration, and you have to set the device up again from scratch on every device you use it with.
Does this answer apply to every Bose model?+
No. It is scoped to 873973. Bose product; Bluetooth multipoint, app generation, wired input and spatial/ANC features vary.
What should I record before troubleshooting reset or factory reset?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing reset, factory reset. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Do not reset the only accessible communication device without an alternative.
