Benefits of your FreeWavz:
- Audible heart rate and other fitness biofeedback without visual distraction-no need for other fitness devices
- Hear music and approaching cars-set the mix independently for each ear
- No annoying wires to catch on your clothes or hair and pull out your earphones
- Won't slip-designed by an ear, nose & throat doctor for natural fit
- Sleek and lightweight-hugs your ears
- Superior quality sound delivered naturally-no jamming or twisting into your ear.
Example: Heart Rate (bpm):
On demand capability allows you to spontaneously tap a button to get heart rate, distance, current time, calories, duration, O2 saturation, etc.
"I’m Adrian Menendez-Maceiras. Training for the ATP Tour is rigorous. FreeWavz keeps me mentally focused and inspired to work through long sets of training on and off the court. No wires to limit my range of motion, they fit perfectly and I get the biofeedback I need to maximize my physical efficiency. I can just focus on preparing for the next tournament with an intensity that makes me feel Unstoppable."
Safety Through Awareness of Your Surroundings
A 2nd set of microphones are positioned just above the earbud, allowing you to set the mix of music and listen-through of your surroundings
- 100% music, 0% listen-through
- 75% music, 25% listen-through
- 50% music, 50% listen-through
- 25% music, 75% listen-through
- 0% music, 100% listen-through
- And since both the left and the right Freewavz are independent, you can separately set the mix for each
FreeWavz App & Compatibility
Gymnast-tested under the most rigorous exercises, FreeWavz don’t move, so you can.
- Approximately 1/2 ounce, or 16 grams, each
- With 6-8 hour battery life, compared to 3-4 hours with other “earplug-like” designs
- FreeWavz will feel like sunglasses resting on the ear--you will forget you have them on

Estimated Battery Life
The 100 mAh batteries in each device are expected to last 6-8 hours between charges, depending on the settings for frequency of fitness testing, and recharge in approximately 1 hour. This compares to 3-4 hours reported by other ear wearable fitness devices. Using normal charging practices, your 100 mAh battery should last over 3 years.
Risks and challenges
FreeWavz uses Commercial Off-the-Shelf (“COTS”) Bluetooth technology with normal range and connectivity limitations. Our design maximizes antenna placement to optimize signal performance and customer satisfaction, but Bluetooth is subject to interference from other devices that operate in the same radio frequency.
The team has extensive experience in hardware and embedded software integration, and extensive medical expertise in the operation of a pulse oximeter; however, we may encounter results that require additional calibration and refinement to produce the desired degree of accuracy.
FreeWavz uses certain key components that are only available from limited manufacturers. If those manufacturers were to discontinue production of these components, it would potentially cause some redesign and a delay in our launch.
Not a Medical Device: FreeWavz fitness results are for informational purposes only. It is not a medical device, nor is it intended to replace your physician or other medical devices that are used for monitoring your health, wellbeing, or the effect of exercise on your physical condition. It will not detect irregularities in an individual’s health. You should always consult a physician before starting a fitness program or if you have any questions regarding a medical condition. We are not responsible for any health issues, including injuries or damages, that may result from exercise, use of our product, or participation in events promoted by FreeWavz. Erroneous readings can be caused by hypoperfusion of the ear (being very cold), wearing of the device in a manner that causes misalignment of the transmitter and receptor so they do not make proper connection, and periodicity of readings that would not detect variations between readings and other variable factors.Learn about accountability on Kickstarter
We have a working prototype in the final go-to-market form factor. We have produced final boards with all electronics to deliver the functionality in this Kickstarter project description.The pictures in the rewards section show the current form, which only needs production machining for finishing the design.
Our founder and inventor, Ear, Nose & Throat Dr. Eric Hensen, gets that question quite frequently in the office with patients naturally concerned about the wear of glasses with other hearing devices, so we kept that in mind when we designed FreeWavz. The thin, flexible neck around the top of the ear allows adjustment for a tighter or looser fit around the ear and the ability to comfortably accommodate eyeglasses or sunglasses.
Several reasons. First, as our medical experts, ENT Dr. Eric Hensen and Au.D. & Board Certified Audiologist, Dr. Leslie K. Rosegger, have advised, the “earbud” area of the ear is highly variable in size and shape and will not provide a secure fit. Second, we have packed each device with electronics and 100 mAh batteries for longer life, which are more efficiently spread around the ear, providing a naturally comfortable weight balance (like sunglasses resting on the ear). Third, the antenna, which provides wirefree connectivity between the two devices, is optimized if located behind the ear. Fourth, it allows positioning of the voice microphone below the ear, closest to the mouth, but shielded from wind by the ear compared to other devices that use bone conduction. As noted by a senior researcher for a speech recognition company, “We’ve been testing bone and throat microphones for years and unfortunately they do not work well for speech recognition…”
Despite suggestions by other wireless products that you can use their devices in the water, water heavily attenuates the signal in certain frequency ranges and will likely result in poor performance. Thus, FreeWavz are not designed for swimming; however, they are sealed with a rubber overmold and are sweat and water resistant.
The Bluetooth Core Specification range for class 2 Bluetooth devices is 10 meters or 32 feet; however, there are several variable in the range of Bluetooth reception that could extend or disrupt the range of signal. In general, your controlling FreeWavz device would need to be within this range to connect to your source device and the other FreeWavz device would need to be within this range if you are sharing with others.
Yes, subject to the Bluetooth range limits referenced above.
Yes. And you can choose whether to pair to the left or right (and as noted above, you can share the other with a friend).
Can I use one FreeWavz and listen to my player while someone else uses the other FreeWavz and listens to their player?
Yes. Another benefit of FreeWavz is that they can be used independently. Each user would need to elect to pair to their respective device (left or right ear) when pairing from their source device. In that case, both users will be able to utilize the fitness monitoring features of the FreeWavz.
Based on calls made with our pre-production prototype, the voice reception is so clear, listeners can't tell we are on FreeWavz Bluetooth headsets.
We will be continuing to release new features that you can upload into your FreeWavz. We will not charge for features that enhance existing capabilities as a fitness wearable device. We would only charge for substantial new capabilities. For instance, if we developed the capability to do two-way language translation (each party wears one and it translates into your/their native language) using your existing hardware, that would be considered a substantial new capability.
Backers at the $179 and $199 reward levels do indeed get a set of the blue FreeWavz, not any kind of discount coupon. We apologize for any confusion in the wording.
Yes, FreeWavz incorporates a 3-axis accelerometer that is already incorporated into the electronic board assembly (which is done and machine-assembled). It is used for steps and distance calculations and can also be used in the future for acceleration, cadence, drop rate, and time at rest and in motion.
FreeWavz are manufactured in Melbourne, Florida, USA, across the street from our offices and close to our engineers to ensure the highest quality production. Virtually all the components are sourced in the USA.
