Quick-20r v2

Wireless Dry EEG Headset
21 Channels EEG + 2 Channels ECG

Completely redesigned.
Increased comfort, signal quality, and ease of use.
With built-in LED impedance measurement

Our most comfortable design now includes built-in LED impedance indicators for real-time contact quality. We introduced the Quick Series headsets 6 years ago to critical acclaim from the research community. And we've been making incremental improvements in signal quality, comfort, and ease-of-use over the years.

The Quick-20r v2 is a complete rethinking of the capabilities of a dry EEG headset. With industry-leading signal quality, active electrodes for unparalleled noise rejection, long-term comfort, enhanced usability, and a unique onboard impedance checking system for instant confirmation.

  • Used the world over in basic research, neurofeedback, and rapid QEEG for guided TMS and other neurodiagnostic research.
  • Quick Series headsets are the best-selling, most popular dry headsets available.


  • Built-in LEDs display real-time impedance contact at each channel
  • Each pod has a built-in adjustment knob to help push aside hair for maximum contact quality
  • 8 hours of battery life from two AA batteries
  • Two variable ExG channels can be used for additional EEG locations, EOG, EMG, or ECG
  • Mechanical design accommodates heads sized 52 to 62 cm in a standard 10-20 configuration — with no positional adjustments needed
  • Lightweight, comfortable design is rated for 60-minute sessions
  • Use with our Wireless StimTrigger for ERP sessions

How Do They Work?

Of course, the two questions we are most often asked are: how do your electrodes work, and how do they compare against conventional wet electrodes?

The answer to the first is simple in theory but complex in practice. CGX dry electrodes work because they are backed by sophisticated mechanics and electronics while most companies focus on a single element, such as the electrode.

The answer to the second is equally nuanced. At CGX, we focus on rigorous internal testing and validation of international standards. This is why researchers around the world use our systems in independent, peer-reviewed publications.

CGX Dry Is A System:

CGX dry electrode headsets are designed holistically:

the electrode, headset mechanics, and electronics are optimized to function as a whole. The end result is the product of thousands of hours of engineering—modelling, prototyping, and optimizing. This results in an advanced mechanical system that's comfortable, secure across a variety of head sizes, and extremely easy to operate.

The Industry’s Best Wireless Amplification:

Our electronics are more than just an amplifier in a box. It's a chain beginning at the tip of the electrode. Each electrode has advanced electrical shielding and pre-amplification which reject extraneous external noise.

From there, the signal travels through a custom-configured wire harness to our sophisticated amplifier.

  • We use the best, low-noise, high-resolution data acquisition electronics on the market. Precise 24-bit A/D converters with >100dB CMRR, microVolt noise floors and active noise cancellation enable robust data collection even under tough, real-world environments.
  • We do no signal filtering or massaging—delivering a research-grade raw EEG signal unmatched in the industry.

Bluetooth Transmission:

And because our systems are so lightweight and power-efficient they can be incorporated into the headset itself and operate for hours with standard batteries. Built-in Bluetooth Low Energy offers up to a 10-meter range for wireless telemetry.
CGX Dry High-Density Systems are also equipped with a custom Bluetooth implementation to transfer higher data rates than what is normally possible with conventional technology.

Real-Time Impedance Checking:

CGX Dry systems contain a variety of advanced circuitry to support researchers. All systems are equipped with a patented real-time impedance monitor to gauge sensor contact quality. For precision timing experiments such as evoked potentials, our systems support an ultra-low latency link to transfer markers with 1-millisecond accuracy without wires.
