  4. Should I buy one or two LifeEar devices?

The brain processes hearing signals from both ears for improved clarity and a more balanced sound. You will be able to hear much better with two hearing devices; your satisfaction with the devices will be much higher. If you use only one hearing device but have hearing difficulty in both ears, the brain has to process two different sound and clarity levels, which makes it more difficult to obtain a clear understanding of the sound signal.
