Main trade-off
Sony ULT FIELD 3
USB cannot play music. Stereo Pair and Party Connect remove multipoint, and multipoint itself has no disable switch.
Head-to-head
Choose Charge 6 for compatible USB laptop audio, with current software and a separate data cable. Choose ULT FIELD 3 for its documented two-phone and calling routine, accepting that stereo and Party Connect remove multipoint. Sony Bluetooth standby needs suitable mains USB-PD power and prior setup. Its phone output also needs the speaker on with enough reserve.
Before you choose
For a desk where the laptop should remain the music source while the phone goes elsewhere, Charge 6 provides the documented USB-audio connection. Sony explicitly says its USB connection cannot play music, so an otherwise suitable charging cable will not solve that desk job. JBL still needs current software, a data cable and USB-mode entry. Unplugging for an outing returns it to Bluetooth, and reconnecting next morning requires that mode step again. Choose Sony when Bluetooth fits the desk and its separate call or standby features solve a more frequent problem.
What this is based on
A room-to-trip routine crossed with the exact purpose of the USB port and the next cable session. No advantage in audio quality or delay is inferred.
Main trade-off
USB cannot play music. Stereo Pair and Party Connect remove multipoint, and multipoint itself has no disable switch.
Main trade-off
USB thumb drives are unsupported. A cable reconnection requires entering USB playback again, and no USB cable is included.
Sony ULT FIELD 3 vs JBL Charge 6 for a kitchen, laptop and day trips. Check USB audio, two-phone limits, group mode and mains-powered standby.
Both fit a room-to-outing routine that may also need phone power. Sony documents a detailed two-phone and call workflow, while JBL supplies a USB-computer route that Sony explicitly excludes. Adding a second speaker or moving away from an outlet changes the Sony setup.
Winner by situation
Sony expressly excludes USB audio. JBL documents a compatible computer route.
Sony documents the workflow and its limits. Equivalent JBL interruption behavior is not established.
Sony expressly removes it. Do not assume JBL supplies the combined requirement either.
Sony provides it after setup, only on suitable mains USB-PD power.

A couple taking turns from two phones can use ULT FIELD 3’s documented multipoint connection on one speaker. Stop the first source if the second does not take over, and remember that incoming calls can involve either connected phone. Adding stereo or Party Connect removes multipoint, so the expanded setup needs a different sharing routine. Sony also provides no global multipoint disable switch, although individual connections can be managed. Charge 6 is the alternative for the wired-laptop job, but its reviewed material does not justify promising a better two-phone interruption policy.
Two household source phones crossed with the change from one speaker to a linked system. The limitation is manufacturer-stated, not inferred from forum reports.
ULT FIELD 3 can suit a shelf where reaching the speaker each morning is inconvenient, provided Bluetooth standby is configured and it stays connected to a suitable mains USB-PD adapter. That convenience disappears on battery alone. Its separate phone-power role also needs the speaker switched on and enough charge left, so turning everything off before leaving does not keep topping up the phone. Both models can help phone power, making the Sony standby arrangement the more specific reason to choose it. Do not buy JBL expecting an equivalent remote-wake policy from its powerbank claim alone.
An always-ready home location crossed with unplugged travel and phone charging after playback. No unverified JBL standby absence or equal output rate is claimed.

Meaningful differences
| What changes | Sony ULT FIELD 3 | JBL Charge 6 | Why it matters |
|---|---|---|---|
| Connect the laptop by cable | USB music playback is explicitly unsupported. | Compatible laptop/tablet USB audio with current software and mode-entry steps. | A laptop USB requirement can settle the choice before battery or grouping features. |
| Share between two phones | Two connected sources, one playing. Calls and handoff have documented conditions. | The reviewed sources establish USB playback, not equivalent two-phone interruption behavior. | Choose Sony for the positively verified workflow, after checking that its restrictions fit. |
| Add a second speaker | Stereo Pair and Party Connect remove two-source multipoint. | Two Charge 6 units for stereo, compatible JBL Auracast units for grouping. | Expansion can change the controls a household uses every day. |
| Leave the kitchen speaker ready | Configured Bluetooth standby requires mains USB-PD power. Phone output needs the speaker on. | Phone powerbank output is documented, with a separate suitable recharge kit needed. | Sony’s documented remote-wake arrangement belongs to the powered home setup, not an unplugged bag. |
What you give up
Recommendation switch
Choose Sony ULT FIELD 3. Choose Sony after accepting its group-mode and mains-power restrictions.
Choose JBL Charge 6. Choose Charge 6, supply the data cable and follow the USB reconnection procedure.
What matters in practice
A speaker shared by two phones can lose that convenience when it becomes part of a stereo or party group.
