Design and materials
The SensaVox is housed in a compact unit with a sleek, high-end finish typical of ElectraStim's build quality. The device features a responsive twist dial for intensity control, clearly laid out with an LED display so you can see your settings at a glance. Dual-channel output means the left and right channels can be controlled independently, letting you fine-tune sensations to different electrodes. The unit arrives in a hard carry case with all accessories included, making storage and transport straightforward.
Control options and customisation
The SensaVox offers three distinct ways to shape your stimulation. The tactile twist dial gives you direct control with 99 intensity levels, plus a boost button that instantly increases intensity by 25% for short bursts—useful for reactive control during play. Nine pre-programmed stimulation patterns provide a starting point, which you can then modulate to suit your mood. Beyond manual control, the included microphone enables voice modulation: the louder you speak or the louder ambient sound becomes, the stronger the stimulation. Similarly, you can connect a music player via the supplied line-in cable, and the SensaVox will sync stimulation intensity to the beat and volume of your music.
Power and battery life
The unit is rechargeable and can also run on mains power via the included worldwide plug adapter. A 9V battery is supplied in the box for backup or travel use. The device includes a power-saving mode to help preserve charge during extended use sessions.
Electrode compatibility
The SensaVox connects to electro-sex toys via 2mm pin connectors and includes two connecting wires in the box. The dual-channel design allows you to use up to four uni-polar electrodes or two bi-polar electrodes simultaneously, giving you flexibility in how you combine toys and sensations.

Cleaning and care

Buy it if
You're experienced with electro-stimulation and want a powerful, feature-rich unit that responds to your voice and music. If you enjoy customisation and want to experiment with different stimulation patterns, or if you like the idea of syncing sensations to audio, the SensaVox delivers multiple control methods in one device. It's also ideal if you want independent channel control to tailor intensity separately for different electrodes.
Skip it if
You're new to electro-play and want something simpler to start with. The SensaVox's 99 settings and voice and music controls offer a lot of flexibility, which can feel overwhelming if you're just exploring the category. If you prefer a more compact, pocket-sized device, this is a substantial unit designed to stay in one place during use.
The bottom line
The ElectraStim SensaVox is a serious, well-built e-stim power box for users who want creative control and responsive feedback. Whether you're using the dial, voice, or music sync, you get precise intensity modulation across two independent channels. It's an investment piece that rewards exploration and experimentation, backed by ElectraStim's reputation for quality manufacturing.
