    1. Product Description

      EM140 SensaVox is the ultimate in electrosex play for couples. Dual channels with individual controls allow you to use up to 4 uni-polar or 2 bi-polar sex toys. The unit can even be controlled by music or your voice and operates via mains or battery power.

      The ElectraStim SensaVox delivers incredible stimulation by sending electronic pulses through any electrosex toy you connect to the unit. Designed with absolute safety in mind and utilising years of research into electro therapy, this expandable kit offers a varied platform for couples electro-play.

      The beauty of this unit is that it has two channels instead of one, each capable of operating either a single bi-polar toy or two uni-polar toys. This allows you and your partner to enjoy different toys, at different intensities, using the same power unit. If you prefer a high-powered buzz and your partner likes a gentle tingle, both of your tastes are catered for.

      Each channel has its own separate control dial, allowing you to adjust the output intensity from level '0' to level '99' one step at a time. This offers incredible control over the intensity of the electric waves and pulses you feel, assuring the sensation is never too much... or not enough. Take it from an incredibly gentle nudge to a vibration-like tingle and onto a sensational shock one step at a time.

      Utilising digital encoder technology means that over four full rotations are required to increase the intensity to the maximum level, ensuring a smooth comfortable climb - although few, if any, can go all the way with this powerful unit.

      If you want some extra oomph during play, press the boost button. This escalates the power for a couple of seconds, tipping you over the climactic edge.

      Choose from either a continuous stimulation or from 9 other patterned programs which behave in the same way as vibrator modes. Each of the patterns is also fully adjustable in intensity for shock-free shocks!

      If you want to spice up play further, try the audio input. This allows you to connect an MP3 player or stereo to the SensaVox unit, making your electronic waves pulse in time with your favourite music. Choose something slow and sexy for long waves or something upbeat for a shorter pulse.

      For extra raunchy play, try the microphone input. This allows you to control stimulation with your voice. Sweet talk, dirty talk or moan and groan to activate the tingling sensations.

      Fitted with the very best in safety technology, the unit will always operate at '0' intensity when you first switch it on. Likewise, when changing patterns, the intensity will always start at '0' to ensure you never experience too much too soon.

      You may power this unit either by using the included 9v battery or via the worldwide mains adaptor, depending on your preference. When operating via battery the unit will power save by dimming the LED display and switching off the display lights after a few seconds. The unit will continue to operate when the display is dimmed, saving power and extending your play.

      Please Note: There are no electrode attachments included with this set. These must be purchased separately. This unit is compatible with any uni-polar or bi-polar toy that accepts 2mm pin connectors.

      Kit includes: An EM140 Power Unit with dual channel control, 2 x connecting wires with 4 x 2mm pin connectors in total, 1 x 9v battery, mains power supply with multiple country adaptors for worldwide play, a microphone, a 3.5mm jack audio lead for MP3 and stereo input, CD, detailed instruction booklet, hard case with removable product sticker.

    1. Best E-stim box I have owned

      Reviewed: June 28, 2014 by smokey4smokey, a Straight Going Steady Male

      I took the leap on this as I have owned many variations of E-stim box over the years, two sets of standard tens machines, one digital and a Zeus 6 channel machine.

      Of all of these the only ones that really did the job were the small tens machines with the manual dials - the first digital one - a Mystim was useless it went from 0 to extreme in one unit. The Zeus 6 channel was the same, you would just go to extreme pain in one go.

      But this unit is amazing. The units are 1 - 100 and they are staggered out properly you don't get to 50 and scream at 51, the dial for intensity has the same fine tuning.

      The box it comes in is excellent and all the bits and pieces complement this device. I have to say, I haven't used the sound input, nor do I feel comfortable when on the programs.

      I have had huge usage out of this without messing with batteries or breaking something. This is the power box for all E-stim users as I can assure you the investment is worth it.

    1. The best sex toy ever

      Reviewed: September 29, 2013 by normchurch, a Straight Married Male

      About a month ago I purchased The Electrastim Sensavox Em 140. This was to replace a P.E.S. powerbox I'd been using for 8 or 9 years. I am, therefore, in a position to make a few constructive comparisons of the 2 devices.

      My faithful PES electrosex box and accessories have served me very well indeed and I've enjoyed innumerable hours of stimulating pleasure. Really the only niggle I had was the fact that there is only one power adjustment (okay there is also a knob for very fine adjustments) which means that if you turn the power up or down on one channel it does precisely the same for the second channel. This means that one channel may be providing just the right stimulation from one accessory but the stimulation from the second accessory is likely to be too weak or too strong. Very difficult to get the right balance.

      Perhaps it is my lack of skill.

      However with the Sensavox each channel can be adjusted separately and consequently the level of stimulation from each channel can be set at pleasurable levels.

      The preset programmes in the device are all extremely good and, I guess, each user will have a particular favourite.

      The microphone works perfectly - with the level of stimulation directly related to the volume and 'type' of the sound.

      What I find to be an absolutely amazing feature is the line in for live music/speech from radio and the line in for signals from the CDrom supplied with the Sensavox. This means that the user has no idea what type of stimulation will be delivered - it will vary in intensity and frequency. I think it's comparable to being stimulated by a partner when you're blindfold. You've no idea what will happen next. FANTASTIC.

      The best toy I've ever bought! Well worth the cost and it's made in England - with a 3 year warranty.

      Very highly recommend.

    1. A toy that gives very intense and prolonged pleasure

      Reviewed: September 15, 2010 by Happy!

      This is the first time I have ever experienced electro stimulation. I have to say it is really fantastic.

      When I got the box it took a little while to figure out how to use it even though it is very simple and intuitive to use. I couldn’t imagine how anyone could be stimulated without being touched especially up to orgasm. After five minutes with the very clear instruction manual I felt ready to give it a try.

      I first tried the self-adhesive pads one at the base of my penis and one near the end. The one problem I encountered with the pads was the fact that my pubic hair got tangled in with them. With a bit of careful repositioning I was good to go.

      When I first switch the box on it automatically resets everything to zero so there are no unexpected jolts. There are 9 programs and 99 intensity levels. On program 1 which gives a constant stimulation I went up to level 10. I don’t know how anyone could handle level 99! I found this was really delightful. My cock throbbed and ached with pleasure.

      I tried different programs and found program 7 to be my favourite up to now. This alternates between the two channels, the controller can handle two toys or two people. With just one channel being used it gives some intense stimulation and then a few moments respite. I found I could vary the length of the stimulation and the pause between. This meant I was able to stay near orgasm without coming for quite while.

      I then switched back to continuous mode and upped the intensity level. This resulted in a very long and very intense orgasm. Unlike an orgasm from a manual or vibratory stimulation there does not come a point where continued stimulation feels uncomfortable. I therefore was able to go on for as long as I wanted. The amount of semen I ejaculated was much more than normal.

      It is also a great pleasure to have the machine do the stimulation and not have to do it yourself. I definitely think it is one of the best ways of enjoying a quiet night in. Hands free is good.

      I am planning to try other toys and to make use of both channels to explore some of the other effects. I have found the manufacturers to be very helpful and speedy in their response to my queries and orders. I am also looking forward to introducing my wife to electro stimulation.

      I totally recommend it despite the price. It is worth every penny.

      Hands free, variable intensities, levels and toys.
      The self adhesive pads are a little difficult to position.
      Bottom line
      Well worth the expense one of the best sex toys around.
