Sumo is a highly powerful hearing aid that fits behind the ear
for both adults and children.

Power where it’s needed
– in the low frequencies

Many people with severe or profound hearing loss can only hear low-frequency sounds, so that’s where Sumo provides more power. And the consistently high output is retained while battery life is preserved.

The advanced digital processing ensures that even with the extra power, voices – including your own – never sound distorted or uncomfortable.

As a Super Power user you require consistently high output, but you also need a battery that lasts. With Sumo, you can have both. Unlike other hearing aids, whose output fades quickly, Sumo’s battery management system minimises the drain on the battery. So you get more consistent output for longer.


More power.
Less space

In the past, the term Super Power was associated with large, rather inelegant hearing aids. But today, Sumo’s unique engineering and design packs more power into less space. Sumo users really appreciate the comfort of a smaller, narrower and lighter design. Contact your hearing care professional to learn more about how Sumo can put more power into your hearing.


Simple to use and reliable

Both the manual volume control and the telecoil switch, which improves sound quality when you are on the phone, are very user friendly. Sumo is also engineered for long-term durability. It’s ideal for active children and is tough enough to withstand the most demanding everyday conditions.
