Head-to-head
Sony ULT FIELD 1 vs UE WONDERBOOM 4: Calls or physical podcast control?
The short answer
Choose ULT FIELD 1 when occasional speakerphone calls or matching an existing FIELD 1 for stereo is the priority. Choose WONDERBOOM 4 for physical Podcast Mode or a compatible WONDERBOOM 3/4 partner. It has no microphone, and Podcast Mode applies only to the 4 in a mixed pair. Sony’s supplied cable supports 1.5 A, so its higher-current charging route needs another suitable cable. Neither USB port plays music, and both need a clean dry connection before charging.
Before you choose
The reasoning and the trade-offs
The next phone call can settle a podcast-speaker choice
WONDERBOOM’s physical Podcast Mode is useful when the phone is put away, but it does not add a microphone. If the same room routine includes answering occasional calls through the speaker, FIELD 1 has the documented controls for that job. Keep Sony’s phone and application limitations in view, and move a private call back to the handset when appropriate. Choose WONDERBOOM when calls are already handled elsewhere and local listening-mode selection is the repeated task. Neither the microphone nor a podcast preset establishes clearer voices or certified conferencing performance.
What this is based on
A podcast session interrupted by a call crossed with explicit microphone support and physical mode control.

About this comparison
Sony ULT FIELD 1 vs Ultimate Ears WONDERBOOM 4 for podcasts, calls and trips. Compare direct controls, exact stereo partners and charging-cable limits.

What matters in practice
The differences that matter
The next phone call can settle a podcast-speaker choice
WONDERBOOM’s physical Podcast Mode is useful when the phone is put away, but it does not add a microphone. If the same room routine includes answering occasional calls through the speaker, FIELD 1 has the documented controls for that job. Keep Sony’s phone and application limitations in view, and move a private call back to the handset when appropriate. Choose WONDERBOOM when calls are already handled elsewhere and local listening-mode selection is the repeated task. Neither the microphone nor a podcast preset establishes clearer voices or certified conferencing performance.
How we reached this conclusion
A podcast session interrupted by a call crossed with explicit microphone support and physical mode control.
A stereo purchase also needs a plan for using one speaker tomorrow
A second FIELD 1 creates the documented Sony stereo pair, and powering the speakers off does not clear that setting. End the pair in the app when the next day calls for separate rooms. WONDERBOOM 4 can instead join a 3 or 4, with a physical exit procedure, but a 3 retains its normal sound mode when the 4 enters Podcast Mode. Choose according to the speaker already owned and the way the pair will be split afterward. Shared music is not evidence that every control or special mode behaves identically across the two units.
How we reached this conclusion
An owned partner followed by separate-room reuse crossed with persistent stereo state and mixed-generation mode behavior.
A faster-looking charger still needs the right cable
FIELD 1’s supplied USB cable supports 1.5 A, the current used for its approximately five-hour full-charge reference while off. Sony also supports a 3 A route, but that requires an appropriate cable rather than merely replacing the wall plug. WONDERBOOM’s roughly three-hour reference assumes a source of at least 10 W. For two outings on the same day, compare the actual supply and cable already available before choosing around those times. With overnight charging, this distinction may matter less than calls or the owned partner. After outdoor use, clean and dry the connection before either refill.
How we reached this conclusion
Limited turnaround time crossed with cable current rating, power-supply requirement and post-use drying. No universal charge-speed winner.

Meaningful differences
What changes the fit
| What changes | Sony ULT FIELD 1 | Ultimate Ears WONDERBOOM 4 | Why it matters |
|---|---|---|---|
| Take an incoming call | Documented speakerphone controls, with device/app limits. | Explicitly no microphone. | Sony provides the call route. UE keeps that task with the phone. |
| Select a listening mode | Physical ULT button, with app EQ. | Physical standard, Outdoor Boost and Podcast mode cycle. | A named local podcast mode is a control difference, not proof of better speech. |
| Add to an owned speaker | Two FIELD 1 units for stereo, retained across power-off. | Double Up with WONDERBOOM 3 or 4. Podcast Mode only changes the 4. | Verify both partner identity and the behavior retained for the next session. |
| Refill before another outing | About five hours at 1.5 A while off. Supplied cable supports 1.5 A. | About three hours with at least 10 W. USB cable is charging-only. | The charger and cable conditions must accompany the reference times. |
What you give up
Every choice has a cost
If you choose Sony ULT FIELD 1
- Five-hour charging reference at 1.5 A while off. The supplied cable does not support the documented higher 3 A current route.
If you choose Ultimate Ears WONDERBOOM 4
- The three-hour reference refill needs at least 10 W. A mode change for one listener should be reset for the next if necessary.
Recommendation switch
The decision flips if...
Calls or matching an owned FIELD 1 is the deciding task
Choose Sony ULT FIELD 1. Choose Sony with phone/app limitations and the retained stereo setting understood.
Physical podcast control or a compatible WONDERBOOM partner matters more
Choose Ultimate Ears WONDERBOOM 4. Choose WONDERBOOM with no microphone and the mixed-generation EQ limit retained.
What matters in practice
Before you choose
A speaker used for podcasts may also need to handle a call, and a suitable stereo partner can matter more than the shared portable label.
What this comparison cannot tell you
- No speech-clarity, call-quality or matched-volume battery comparison.
- Neither USB port provides music playback.
- Selected packages are Off White Sony and Black UE single speakers.
