The 2ners were a direct outgrowth of my involvement in the bicycle industry and addressed the issue of people riding with ear buds or head phones. There were numerous consumer requests for something that allow rider to experience their music that was safe and comfortable. In the case of cycling this has a serious drawback in that you were isolated from the environment and could not hear approaching autos or safety vehicles. The other problem was that all of the existing units used wires to a remote player/radio making for a problem when removing a helmet or during spirited activity. The few existing head phone type radios were far too bulky to be used in active sports even though some were used in running and jogging but there size and mass made them uncomfortable for use as well as isolating.
The 2ners development as all headphone type radio systems do hinged on the question of power requirements and there for the battery size. Providing enough power to give good volume and sound quality over a reasonable amount of time between battery charges or replacements is the key issue. Other systems use AA or AAA batteries and full coverage head phones to achieve the goal but that was obviously not acceptable for this application as they were far larger than desired. The state of micro electronics and speakers however did show that it might be possible. And the solution turned out by utilizing all the available energy both mechanical as well as electronic I could keep the size down.
The 2ner used a couple of innovative methods to provide excellent sound quality with minimal energy requirements and these ultimately lead to the ability to package the system small enough for active sports. The product and was a total ground up design entailing electronics, acoustics, packaging, biomechanics and aesthetics. The primary method was utilizing the body of the unit and its circuit board to make a tuned cavity to enhance bass response with bone conductance to further enhance bass. This was achieved by turning the speaker around so the voice coil enclosure rested on the persons cheek allowed for a much smaller speaker size to be used lowering the amplifier size and limiting the systems power consumption. The other key element was the use of directed speaker ports that aimed the high frequency parts of the sound into a zone of the ear that naturally funnels these frequencies into the inner ear. The shape of the unit provides a wind shield effect reducing the effect of wind noise as well as fitting well with bicycle helmets. The elimination of extraneous features such as a display for station and time was integral to keeping the unit’s size compact.
The full feature FM 88-108 MHz with PLL tuning allowed for its use with available small FM transmitters providing a wireless link from a Discman or MP3 player so the user could listen to their own music not just broadcast radio.
I had planned on an evolution of the product with a built in MP3 flash memory chip contained in the right battery box area. This would have given us a lead on many of the majors for ultra small MP3 players and eliminated the need for the transmitter. This follow on product was keyed to be in place after 9 months of sales of the first unit and followed normal product evolutionary product pathways.
The unit received good marks from its testers including Wired magazine whom said in their august 2001 issue “The pod’s combination of light weight and clean sound quality-a mere 1.5 oz and a range of 40-20,000 Hz made up for its defects. Revolutionary? Not quite. But 2ners provide an inexpensive wireless alternative to the usual ear buds and clamshell.-Tiffany Lee Brown”.
Vann Schaffner had this to say about his 2ners “I’ve been using the 2ners for about two weeks now. I use them most often bicycling, but also around the house while reading. I can’t wait to get a transmitter so I can have wireless CD, sometimes the radio get boring.
They are very comfortable and fit nicely under a helmet. They do not affect the helmet fit at all. My commuting ride is 1 ½ long and I have not noticed any discomfort wearing them that long. Not only are they comfortable, but they also fit nicely under my balaclava that I wear for cold weather. The fit is very stable and should work nicely for running or other sports with more up and down motion.
The sound is exceptional, very high quality. The sound is equal or superior to a quality pair of headphones. However, with the 2ners, I am able to set the volume so that I can hear the ambient noise, which is very important on a bicycle. I can hear traffic very easily, and I don’t have that sensation of being in a different world. I am connected by sound to the world around me, but still able to enjoy great music.
The controls are very easy to use, and with a little practice I can easily change the frequency or volume. I can even do it with heavy winter gloves, under the balaclava. The digital reception also ensures that if I get a weak signal there is none of that maddening static. No signal, no noise.
The unit is very light, as are the batteries. I get about 4 round trips to and from work on a charge. The recharge unit is light enough that I have no qualms about taking it along in my backpack. The batteries are conveniently stored in the recharge case, making a handy unit to carry along. I think that with a little practice, I can also change the batteries without removing the unit or my helmet. I’d like to get another battery set, for longer trips.
What else can I say? I love them, and use them all the time. After all, what better way to get into a rhythm that some great tunes!”

The original business model was to sell or license the technology to an operating firm and after doing show and tell to the likes of Nike, Schwinn, and Vetta. In general, selling new products to existing companies revolved around the ability to show consumer acceptance and was the core of the sales resistance from the large firms. We did not expose the product to the large consumer products companies as we were disruptive technology and access to the C level management had always been a challenge.
I’ve had some experience with consumer direct response sales via TV (infomercial companies) and knew that they sometimes were willing to do joint ventures on products where they would assist in the startup production of a new item, as well as handling the marketing of the product. We decided to pursue this matter and over the course of 5 meetings, a very lucrative contract was entered into with the infomercial giant Guthy-Renker for joint venture and exclusive distribution.
The contact negotiations took months and were a mine field of details concerning minimum annual royalty payments, territories, internet sales, price, cost, and delivery.
During this time I contacted two manufacturing companies in Hong Kong for the production of the product and worked with their engineers to bring it into a mass producible state. Also during that time, questions of packaging, instruction manuals, graphics and logo were also addressed by me.
During the normal startup process time of eight months some key decisions at Guthy-Renker had been made and they had decided to stick exclusively with consumable products. This change presented me with two options– I could force them into court to “cure” us as per the contract or proceed to market myself and leave the relationship intact.
I then decided that sales via online web site and viral marketing would work. I generated a website for the marketing and sales of the product, and it was selling quite well until the majority partner in the project decided that he would prefer to transfer the technology to a major company.
In 2004 (three years after the 2ner introduction), Oakley introduced a sunglass system with a built in MP3 player approximating the size of the 2ner but at a much higher price point. Koss audio and Panasonic both produced a line of headphones using aimed tuned ports to enhance audio experience as was pioneered in the 2ner.
