Head-to-head
Choose Kilburn III for physical bass and treble controls and direct AUX, with a suitable wall charger added and connected Bluetooth sources paused for AUX. A separately configured Heddon can extend its home role. Choose Move 2 to join existing Sonos rooms and return to its included powered base. Move 2 line-in needs a separate adapter and an ongoing home-network connection. Neither IP54 Kilburn nor IP56 Move 2 has an immersion rating.
Before you choose
When one person’s phone starts the music and another wants to change the bass, Kilburn’s physical knobs remove the need to locate that phone or open an app. Move 2 puts manual bass and treble settings in the Sonos app and can adjust itself through auto Trueplay when its microphones are enabled. That automatic function does not replace a listener’s preference. If microphones must be physically off, auto Trueplay is off too. If only voice commands are unwanted, the separate voice-services control can leave tuning available. Choose Kilburn for direct shared access, or Move 2 when the configured home system and that microphone preference fit. No quieter-neighbor or health outcome follows from either control.
What this is based on
Different household members control music at different times, while a microphone preference changes which automatic function remains available. This is access and setup reasoning, not an acoustic performance measurement.
Main trade-off
The wall supply is separate. Heddon grouping needs a separately configured hub and current firmware. The optional Listen to Broadcast app-beta route repeats setup each session. IP54 covers splashes rather than immersion.
Main trade-off
Initial app and Wi-Fi setup is required before Bluetooth. Line-in adds a Sonos adapter and an ongoing home-network connection over Wi-Fi or Combo Adapter Ethernet. Tone settings are adjusted through the app.
Marshall Kilburn III vs Sonos Move 2 for a shared living room, an older player and patio use. Compare physical tone controls, line-in hardware and charging kits.
Both are substantial battery speakers often used at home and occasionally carried outside. Actual buyers cross-shop them when one household wants easy controls and another already uses a Sonos system.
Winner by situation
Kilburn supplies physical bass and treble controls. Move 2’s manual EQ is in the app, and auto tuning depends on enabled microphones.
Kilburn provides direct AUX after connected Bluetooth sources are paused. Move 2 adds an adapter and ongoing home-network connection. Both need the correct source level and cable.
Move 2 supplies that configured-system role and included charging kit. Kilburn’s Heddon route uses a separate configured hub and does not join the Sonos group.
Kilburn III is listed for the button-press route with current firmware. Add its suitable wall supply. A Sonos badge does not establish Heddon compatibility.

Different household members control music at different times, while a microphone preference changes which automatic function remains available. This is access and setup reasoning, not an acoustic performance measurement.
A suitable analog player can connect to Kilburn’s AUX through the correct cable. When someone has been playing phone music, pause every connected Bluetooth source before using AUX. Move 2 adds a separate Sonos adapter and needs the configured home network throughout playback, using Wi-Fi or Combo Adapter Ethernet. That extra kit earns its place when records are part of the Sonos listening routine. When player and speaker simply share one shelf, Kilburn avoids the adapter, though the phone-to-AUX handoff remains. Raw cartridge output can need a phono preamp in either case, and neither input proves zero delay for a live instrument. Disconnect the source lead before carrying either speaker outside.
A fixed analog source, shared phone playback and patio use share one speaker. The adapter, network and source-handoff duties matter differently when records stay on one shelf or join the home system.
If Sonos already plays in several rooms, Move 2 joins that arrangement after setup and brings its powered charging base. Kilburn can also join a prepared home setup through a separately purchased Heddon hub. With current firmware, its documented button-press route joins the configured hub, which the listener selects in a supported streaming app. The separate Listen to Broadcast app beta repeats its setup each session, so agree which route the next person will use. An owned Heddon makes Kilburn a sensible addition. An owned Sonos system favors Move 2 over buying and configuring another hub. Count Kilburn’s wall charger too. Ordinary single-speaker Bluetooth does not need Heddon.
Existing household equipment and the next person’s playback routine determine whether the purchase extends a prepared system or adds another hub, app setup and charging supply. The beta route is kept separate from button-press Heddon support.

Meaningful differences
| What changes | Marshall Kilburn III | Sonos Move 2 | Why it matters |
|---|---|---|---|
| Someone else wants less bass | Physical bass and treble controls. Ordinary playback works without the app. | Bass and treble adjusted in the Sonos app. Auto Trueplay depends on enabled microphones. | Kilburn gives the person at the speaker direct adjustment. Automatic tuning and manual preference are separate decisions. |
| Connect the player already owned | Direct 3.5 mm AUX. Pause all connected Bluetooth audio sources for AUX playback. | Separate Sonos Line-In or Combo Adapter plus an ongoing home-network connection. Combo supports Ethernet and analog input together. | Count source level, the complete cable path and the handoff from phone music. Move 2’s adapter makes sense when its networked role is used. |
| Leave a charging spot ready | USB-C cable in the listed box. Three-hour recharge reference uses a separate 30 W USB-C PD supply. | Indoor charging base and 45 W USB-C PD supply included. | An owned matching supply can complete Kilburn. Move 2 already includes the powered base arrangement. |
| Share music beyond this one speaker | Configured Heddon hub supports a button-press connection with current firmware. The separate app-beta route repeats its setup each session. | Home Wi-Fi grouping, plus supported Play/Move 2 offline groups after same-household setup. Stereo still needs Wi-Fi. | An existing Heddon or Sonos system changes what must be bought and prepared. Neither creates universal group compatibility. |
| Use outside and bring it back | IP54 resistance, not an immersion rating. | IP56 resistance. Charging base must remain dry indoors. | Choose a suitable dry charging location and do not transfer IP67 assumptions from another portable. |
What you give up
Recommendation switch
Choose Marshall Kilburn III. Kilburn provides both on the unit. Pause connected Bluetooth sources for AUX, add a suitable wall supply and retain IP54 limits.
Choose Sonos Move 2. Move 2 fits that routine after setup. Line-in adds its adapter and ongoing home-network connection. Retain the microphone preference when counting automatic tuning.
What matters in practice
Kilburn gives whoever is in the room direct tone controls and AUX. Move 2 adds a home-system role, with app setup and different privacy and adapter decisions.
