Concha Labs has Making acoustic appliances from the counter since 2017, marketing only a product: the concha sol.

Acoustic appliances have a family design, a classic configuration behind the ears with a simple rocker control on the back of each one. Concha, in particular, tells its customization: the Sol is available in your choice of four colors and can be configured with lead threads in four different sizes, although it should be noted that many competing acoustic devices have lead wires that can be regulated on the fly and replaced with larger or smaller ones.

At the time of your order, Concha works to convert the acoustic appliances to the size of the ears, the tone of the skin and the color of your hair (if you are lucky enough to have some left), maximizing the probability in which it merges and will adapt correctly. I received the gray model with the longest leads available and measured the weight of these devices at 2.03 grams, which is very light for the hearing aids behind the ears.

Replaceable batteries

The main reason behind such a light weight is the largest negative aspect of the Sol: replaceable batteries. It is a bit not started in the world of today’s hearing aids, and it is surprising that Concha Labs is still clinging to a faded power model that requires the user to fool with a slide in a new pair of small batteries every 5-7 days. While the replaceable batteries offer a much longer duration than the best rechargeable cells (as well as the lightest weight above), they are still a hauling of which few enjoy. (The last research I have seen, since 2021, showed it 70 percent of users of hearing aids prefers rechargeable hearing systems.

Assuming that you are well with a replaceable battery system, the concha Sol has a lot to do for them. Start with the development. Concha does not use preset sound profiles like most OTC aid. Preset profiles are prandous frequency wave forms based on thousands of historical hearing tests that people have carried out over the years. These audiograms are mediated and a handful of representative audiograms are loaded on hardware. When performing an in-app hearing test, the app understands which of these audiograms is closer to yours and loads the appropriate corrections in the hardware of hearing aids. It is not perfect, but for most users it is quite good.

Concha has an integrated hearing test in its app, but is completely different from the typical hearing test, in which you listen to pings at different frequencies and volumes until a complete picture of the hearing loss develops. After a few initial levels, the conchas system, called Soundscope, asks you to listen (with every ear) to repeated led and repeated language snappets, then identify whether the sample A or the B sample sounds better. It is like an eye exam, only for your ears.
