If you have difficulty hearing parts of conversations, then you can assume that the DX Series will benefit you. If you cannot hear conversation unless voices are raised significantly, then the likelihood of benefit from the DX Series will be slim.

If you are unsure about your level of hearing loss, it is advisable to book a professional hearing test. Hearing tests are widely available through high-street providers such as Specsavers, Boots Hearingcare, Puretone preferred network, or independent audiologists. They are often free of charge or offered at a low cost (typically £20–£50 if not free).

Your GP may also be able to refer you for a test through the NHS. A hearing test will provide you with an audiogram that clearly shows your hearing thresholds across different frequencies, giving you a reliable basis for deciding whether the CENS DX Series or another solution is right for you.

Regular hearing checks are recommended, especially if you notice changes in your ability to follow conversations, hear high-pitched sounds, or if family and friends comment on your hearing.
