The Creative Muvo Flex delivers audio through a single driver with an output power of 10W, covering a frequency range of 115 Hz to 20,000 Hz. A passive radiator is present to help reinforce low-end output, though the speaker does not include a dedicated subwoofer or stereo speaker configuration. It features one built-in microphone, which does not have noise-canceling capability, and the unit lacks magnetic shielding.
The Creative Muvo Flex is equipped with a built-in rechargeable battery offering up to 10 hours of playback, and a battery level indicator is included to help track remaining charge. The battery is not removable, and the speaker does not support wireless charging, so recharging is handled through a wired connection.

It includes one USB Type-C port but does not offer a 3.5 mm audio jack socket, AUX input, 3.5 mm male connector, or external memory slot. On the audio codec side, aptX, aptX HD, aptX Adaptive, aptX Lossless, aptX Low Latency, AAC, LDAC, and Bluetooth LE Audio are all absent. NFC pairing, Wi-Fi, AirPlay, Chromecast, DLNA, Ethernet, and a microphone input are likewise not supported.
The Creative Muvo Flex can be used wirelessly and supports smartphone remote control, allowing playback to be managed from a connected device. It includes voice prompts for audio feedback and a sleep timer for scheduled shutoff. Fast pairing, voice commands, a mute function, built-in radio, and power bank functionality are not available on this speaker.
