A USB plug attached to a speaker does not make every USB socket an audio source. With Creative Pebble V3, model MF1700, draw the power and audio routes separately before deciding how it will work at your desk.
Creative’s technical specifications identify USB audio, Bluetooth and a 3.5mm analogue input. Its parts guide describes the attached Type-C cable and identifies the 3.5mm socket as AUX In, not a headphone output.
| Intended route | Question to resolve |
|---|---|
| USB audio from a computer | Does that computer support the documented USB-audio route? |
| Bluetooth playback | What device sends audio, and what separately powers the speakers? |
| 3.5mm AUX playback | Does the source have an analogue output, and is speaker power still provided? |
A charger is not the missing music source
A wall power adapter can supply power without supplying an audio programme. If you use that arrangement, identify the Bluetooth or analogue source as well. Conversely, a computer connection intended to carry audio still needs to meet the product’s power requirements.
The V3 FAQ explains that output and gain behaviour depend on the power arrangement, including its documented 5V 2A case. Follow that model-specific guidance rather than assuming a high-wattage charger makes every setting appropriate. This article does not propose alternate voltage or wiring arrangements.
Check the complete desk layout
Identify the source, the chosen input, the power supply and where the two speakers will sit. Include cable reach and access to the source control in that sketch. A switchable monitor USB port or a hub in the intended route should be understood from its own documentation rather than assumed to behave like a direct computer connection.
Our preference would be to resolve the two paths before buying adapters. It prevents the common mistake of adding a cable that physically fits while leaving either the audio source or the power requirement unresolved.
